📅
⏱️ 18 min read
👤 By Mr. Adam [Aqeel Abbas]

Birthstones have fascinated humanity for centuries, connecting us to the earth's treasures through the month we were born. The modern birthstone list, officially established by the American National Retail Jewelers Association in 1912 (and updated by the Jewelry Industry Council), offers a standardized guide that jewelers and gem enthusiasts follow today.

Whether you're discovering your own birthstone or searching for a meaningful gift, this comprehensive guide explores each month's modern birthstone, revealing their unique properties, symbolism, and timeless beauty.

Modern Birthstones

The modern birthstone list prioritizes availability and commercial appeal, making these beautiful gems accessible to everyone while maintaining high quality standards and symbolic meaning.

January

Garnet - The Stone of Protection and New Beginnings

January's birthstone welcomes the new year with the rich, warm hues of garnet. While most people associate garnets with deep red, these versatile gems surprise us with an incredible color range spanning orange, green, pink, and even rare purple varieties. Only blue remains absent from garnet's color palette.

The pyrope garnet, with its wine-red brilliance, remains the most beloved variety. Ancient warriors carried garnets into battle, believing these stones offered protection and courage. Today, garnets symbolize friendship, trust, and loyalty.

Properties

  • Color range: Deep red, orange, green, pink, purple
  • Hardness: 6.5-7.5 on the Mohs scale
  • Durability: Excellent for everyday wear
  • Symbolism: Safe travels, peaceful dreams, enduring friendship
  • Perfect for: Rings, necklaces, earrings, and statement pieces

February

Amethyst - The Royal Purple Gem

February brings the enchanting purple amethyst, a gemstone treasured by royalty for millennia. The name derives from the Greek word "amethystos," meaning "not drunk," reflecting ancient beliefs that this stone could prevent intoxication.

From light lilac to deep royal purple, amethyst's majestic color range has adorned the crowns and jewelry of European monarchs throughout history. The deepest, most prized purple specimens come from Uruguay and Zambia, though beautiful amethysts are found worldwide.

This stone represents clarity of mind, inner strength, and spiritual awareness. Many practitioners use amethyst during meditation, drawn to its calming energy and connection to higher consciousness.

Properties

  • Color range: Light lilac to deep royal purple
  • Hardness: 7 on the Mohs scale
  • Durability: Suitable for all jewelry types
  • Symbolism: Mental clarity, spiritual growth, peace

Affordability Note

Compared to other precious gems, amethyst offers remarkable beauty at accessible prices, allowing you to own substantial, stunning pieces.

March

Aquamarine - The Breath of the Sea

March babies claim one of the most serene gemstones: aquamarine. Its name literally translates to "water of the sea" in Latin, perfectly capturing the gem's essence. Sailors once carried aquamarine as a protective talisman, believing it ensured safe passage across treacherous waters.

The soft blue-green hues evoke tropical waters and cloudless skies. As a member of the beryl family, aquamarine shares its lineage with emeralds, though their personalities differ dramatically. What distinguishes aquamarine is its exceptional clarity—most specimens contain minimal inclusions, creating crystal-clear transparency that mesmerizes when light passes through.

Properties

  • Color range: Pale blue to deep blue-green
  • Hardness: 7.5-8 on the Mohs scale
  • Durability: Excellent for engagement rings and daily wear
  • Symbolism: Youth, hope, health, fidelity

Why It's Special

The remarkable clarity and tranquil color make aquamarine perfect for statement jewelry and engagement rings.

April

Diamond - The Timeless Classic

April claims the crown jewel of gemstones: the diamond. These extraordinary stones have captivated humanity for centuries with their unmatched brilliance and fire. A well-cut diamond captures and reflects light like no other substance on Earth.

Formed deep within the earth under extreme pressure and heat over billions of years, diamonds represent nature's most impressive feat of transformation. As the hardest natural substance known to humans, diamonds symbolize eternal love, strength, and invincibility.

While colorless diamonds remain traditional favorites, diamonds actually occur in fascinating colors including yellow, pink, blue, green, and even exceptionally rare red. Each diamond is unique, bearing its own distinctive fingerprint of inclusions and characteristics.

Properties

  • Color range: Colorless to fancy colors (yellow, pink, blue, red, etc.)
  • Hardness: 10 on the Mohs scale (the hardest natural substance)
  • Durability: Virtually indestructible for everyday wear
  • Symbolism: Love, commitment, strength, eternity

Investment Value

Diamonds retain value exceptionally well, making them both emotionally and financially significant.

May

Emerald - The Green Treasure

May introduces the lush, verdant emerald. Cleopatra famously adored these gems, and ancient Egyptians mined emeralds as early as 1500 BCE. Despite diamonds receiving more attention, emeralds are actually rarer, commanding impressive values in the gem market.

Like aquamarine, emeralds belong to the beryl family. Traces of chromium and sometimes vanadium create their gorgeous green color. Most emeralds display visible inclusions that jewelers poetically call "jardin" (French for garden) because they resemble tiny vines and foliage within the stone.

This gemstone represents rebirth, fertility, and love. Each emerald possesses unique character—no two are exactly alike, making every piece distinctly personal.

Properties

  • Color range: Yellowish-green to bluish-green
  • Hardness: 7.5-8 on the Mohs scale
  • Durability: Good, but requires gentle care
  • Symbolism: Rebirth, fertility, love, wisdom

Care Note

Avoid ultrasonic cleaners with emeralds; gentle soap and lukewarm water work best.

June

Pearl, Alexandrite & Moonstone - A Triple Choice

June celebrates abundance with three distinct birthstone options, each offering unique beauty and symbolism.

Pearl: Nature's Organic Gem

Unlike gemstones mined from the earth, pearls form inside living oysters and mussels. This organic origin makes them extraordinarily special. Pearls symbolize purity, innocence, and wisdom gained through experience.

Cultured pearls have made these elegant gems accessible to everyone, allowing more people to enjoy their lustrous beauty. From classic white to cream, pink, and even black Tahitian pearls, the variety is stunning.

Pearl Properties

  • Colors: White, cream, pink, gold, black
  • Hardness: 2.5-4.5 on the Mohs scale
  • Care: Very delicate; avoid chemicals and prolonged water exposure
  • Symbolism: Purity, innocence, wisdom

Alexandrite: The Color-Changing Marvel

Alexandrite performs magic before your eyes. This rare stone appears green in daylight but transforms to purplish-red under incandescent light. Discovered in Russia's Ural Mountains in the 1830s, alexandrite was named after Czar Alexander II.

This extraordinary color-change phenomenon makes alexandrite one of the most valuable gemstones. It represents balance, joy, and good fortune.

Alexandrite Properties

  • Color change: Green (daylight) to purplish-red (incandescent light)
  • Hardness: 8.5 on the Mohs scale
  • Rarity: Extremely rare and valuable
  • Symbolism: Balance, joy, luck

Moonstone: The Mystical Glow

Moonstone displays a captivating phenomenon called adularescence—a milky, bluish glow that appears to float across the stone's surface as you move it. Ancient Romans believed moonstone formed from frozen moonlight.

This ethereal gem brings mystery and romance to June, perfect for those drawn to understated elegance with a touch of magic.

Moonstone Properties

  • Color: White, cream, peach with blue sheen
  • Hardness: 6-6.5 on the Mohs scale
  • Special effect: Adularescence (billowy glow)
  • Symbolism: Intuition, femininity, new beginnings

July

Ruby - The King of Gems

Ruby's intense red color has made it one of history's most coveted gemstones. In Sanskrit, ruby is called "ratnaraj," meaning "king of precious stones"—a title that perfectly captures its regal status.

Rubies are red corundum, sharing the same mineral family with sapphires. Chromium creates their vivid red color. The finest rubies, known as "pigeon's blood," originate from Myanmar and display pure red with a subtle hint of blue.

This passionate stone represents love, energy, courage, and vitality. Ancient warriors wore rubies believing they granted invincibility in battle. Today, rubies remain powerful symbols of romance and life force.

Properties

  • Color range: Pinkish-red to deep blood red
  • Hardness: 9 on the Mohs scale
  • Durability: Excellent for all jewelry types
  • Symbolism: Love, passion, courage, protection

Value Note

Large, fine-quality rubies often command higher prices per carat than diamonds.

August

Peridot & Spinel - Green Fire and Rainbow Brilliance

August offers two spectacular birthstones, each with distinctive character.

Peridot: The Gem of the Sun

Peridot brings fresh, lime-green sparkle to summer's height. This unique gemstone stands apart as one of the few that occurs in only one color, though shades range from yellow-green to olive to brownish-green. Ancient Egyptians called peridot the "gem of the sun."

Remarkably, peridot has been found in meteorites, making it literally extraterrestrial! The stone symbolizes strength, vitality, and healing energy.

Peridot Properties

  • Color: Yellow-green to olive to brownish-green
  • Hardness: 6.5-7 on the Mohs scale
  • Origin: Earth and outer space (meteorites)
  • Symbolism: Strength, healing, vitality

Spinel: The Misunderstood Beauty

For centuries, spinels were confused with rubies—even famous "rubies" in royal crown jewels turned out to be spinels! The British Imperial State Crown's "Black Prince's Ruby" is actually a magnificent red spinel.

Modern gemology has given spinel its rightful recognition. Available in brilliant reds, pinks, oranges, purples, and blues, spinel offers exceptional beauty and durability.

Spinel Properties

  • Color range: Red, pink, orange, purple, blue
  • Hardness: 8 on the Mohs scale
  • Durability: Excellent for daily wear
  • Symbolism: Energy, passion, devotion

September

Sapphire - Beyond Blue

When people think "sapphire," deep blue immediately comes to mind. While blue sapphires reign as the most famous variety, sapphires actually exist in nearly every color: pink, yellow, orange, purple, green, and even color-changing varieties.

Here's the fascinating distinction: sapphires and rubies are both corundum. The only difference is color. Red corundum is ruby; every other color of corundum is sapphire. The most prized blue sapphires originate from Kashmir, Burma, and Sri Lanka.

Sapphires represent wisdom, loyalty, nobility, and sincerity. Their durability and stunning beauty make them increasingly popular for engagement rings. Princess Diana's iconic blue sapphire ring (now worn by Catherine, Princess of Wales) sparked renewed interest in sapphire engagement rings.

Properties

  • Color range: Blue, pink, yellow, orange, purple, green, white
  • Hardness: 9 on the Mohs scale
  • Durability: Exceptional for all jewelry types
  • Symbolism: Wisdom, loyalty, nobility, truth

Special Variety

Padparadscha sapphire, displaying a rare salmon-pink-orange color, is among the most valuable sapphires.

October

Opal & Tourmaline - A Rainbow Celebration

October celebrates diversity with two gemstones that showcase nature's full color spectrum.

Opal: Nature's Kaleidoscope

Opal is pure magic. This gemstone displays "play-of-color," where flashes of rainbow colors dance across its surface as you move it. No two opals are identical—each represents a unique work of natural art.

Ancient Romans considered opal the most precious gem because it contained all colors. Australia produces approximately 95% of the world's opals, though beautiful specimens come from Ethiopia, Mexico, and other locations.

Opal Properties

  • Color: White, black, boulder, fire opal with rainbow play-of-color
  • Hardness: 5.5-6.5 on the Mohs scale
  • Care: Delicate; avoid harsh chemicals and extreme temperature changes
  • Symbolism: Hope, creativity, innocence, inspiration

Tourmaline: The Rainbow Gem

Tourmaline offers more color variety than any other gemstone. Pink tourmaline, green tourmaline, blue indicolite, watermelon tourmaline (pink center with green edges), and even rainbow tourmalines with multiple colors in a single crystal—the options seem endless.

This versatile stone provides something for every taste and personality.

Tourmaline Properties

  • Color range: Pink, red, green, blue, yellow, purple, multicolored
  • Hardness: 7-7.5 on the Mohs scale
  • Durability: Good for most jewelry applications
  • Symbolism: Healing, protection, creativity

November

Topaz & Citrine - Golden Warmth

November brings warmth to autumn's chill with two golden gemstones.

Topaz: Imperial Elegance

Topaz achieves fame in its golden orange-brown variety, called imperial topaz. However, topaz naturally occurs in many colors, with blue topaz particularly popular today. Pure topaz is actually colorless—colors result from impurities or treatment.

This stone represents love, affection, and strength. Ancient civilizations believed topaz could dispel enchantments and improve eyesight.

Topaz Properties

  • Color range: Colorless, blue, yellow, orange, pink, red
  • Hardness: 8 on the Mohs scale
  • Durability: Good, but avoid sharp blows (has perfect cleavage)
  • Symbolism: Love, affection, strength, intelligence

Citrine: Sunshine in a Stone

Citrine brings sunshine to November with warm yellow to orange-brown hues. Natural citrine is quite rare; most citrine available today is heat-treated amethyst or smoky quartz. This transformation doesn't diminish its beauty or value—it simply makes citrine more accessible.

This affordable gemstone symbolizes success, prosperity, and joy. Many consider citrine a merchant's stone, believed to attract abundance.

Citrine Properties

  • Color range: Light yellow to deep orange-brown
  • Hardness: 7 on the Mohs scale
  • Durability: Excellent for all jewelry types
  • Symbolism: Success, prosperity, joy, abundance

December

Turquoise, Tanzanite & Zircon - Winter Blues

December closes the year with three stunning blue options, each bringing unique beauty to winter.

Turquoise: Ancient Treasure

Turquoise ranks among humanity's oldest gemstones, treasured for thousands of years across cultures. Native Americans consider it sacred, believing it connects the earth and sky. Persian turquoise was particularly prized along ancient trade routes.

Its distinctive robin's egg blue color, often with brown or black matrix veining, is instantly recognizable. Turquoise represents good fortune, protection, and success.

Turquoise Properties

  • Color: Sky blue to blue-green, often with matrix
  • Hardness: 5-6 on the Mohs scale
  • Care: Porous; avoid chemicals, lotions, and prolonged water exposure
  • Symbolism: Protection, good fortune, friendship

Tanzanite: The Modern Discovery

Tanzanite is a relative newcomer, discovered in Tanzania in 1967. This violet-blue stone exists in only one place on Earth, making it geographically rarer than diamonds. The Maasai legend tells of lightning striking the hills, transforming brown zoisite crystals into beautiful blue tanzanite.

The stone's color shifts from blue to violet depending on viewing angle, creating captivating depth. Tanzanite has quickly become one of the most desired colored gemstones.

Tanzanite Properties

  • Color: Violet-blue with pleochroism (color shift)
  • Hardness: 6-7 on the Mohs scale
  • Care: Avoid ultrasonic cleaners and sudden temperature changes
  • Symbolism: Transformation, spiritual awareness, enlightenment

Zircon: The Brilliant Alternative

Zircon (not cubic zirconia—they're completely different) comes in various colors, but blue zircon is December's traditional choice. This brilliant natural gemstone displays exceptional fire and luster, rivaling diamonds in sparkle.

Zircon is one of the oldest minerals on Earth, with some crystals dating back 4.4 billion years. Blue zircon's color typically results from heat treatment of brown zircon.

Zircon Properties

  • Color range: Blue, colorless, yellow, brown, green, red
  • Hardness: 6-7.5 on the Mohs scale
  • Special quality: Exceptional brilliance and fire
  • Symbolism: Prosperity, honor, wisdom
