What Makes a Birthstone Expensive
The price of a birthstone depends on more than just beauty. Factors like rarity, color, and demand determine which gemstones become the most expensive birthstones in the world.
- Rarity – Stones found in only one geographic region, such as tanzanite from Tanzania, are naturally more valuable.
- Color and clarity – The more vivid and pure the color, the higher its worth.
- Carat size – Larger gems with flawless transparency fetch exponentially higher prices.
- Treatment and origin – Untreated stones from legendary mines like Burma (rubies) or Kashmir (sapphires) often achieve premium value.
- Market demand – Diamonds, emeralds, and sapphires remain timeless due to centuries of global admiration.
- Durability – Harder stones, such as sapphire and diamond, retain brilliance for decades.
Each of these elements determines whether a gem remains an accessory — or becomes a treasure.

January – Garnet
Known for its deep red glow, garnet symbolizes protection and vitality.
While common red garnet is affordable, rare varieties like demantoid garnet are highly coveted for their fiery brilliance and scarcity.
Collectors value demantoid’s green hue and diamond-like sparkle, making it one of the most valuable January gemstones.
This makes garnet not just January’s birthstone, but one of the most collectible gems for connoisseurs of color and brilliance.
February – Amethyst
The rich, royal purple of amethyst has long been linked with luxury and clarity of mind.
Deep-toned, untreated amethysts from Siberia or Brazil are especially valuable, and antique cuts further enhance their worth.
Though once considered as precious as sapphire or ruby, amethyst remains a timeless, elegant gemstone.
March – Aquamarine
Aquamarine captures the serene beauty of the sea.
Its value increases with color depth—stones showing a strong “Santa Maria Blue” hue command premium prices.
High-quality aquamarine is often left untreated, appreciated for its natural clarity and calming blue tone.

April – Diamond
The diamond stands as the ultimate symbol of strength, purity, and eternal love.
It’s not only the most expensive birthstone overall, but also the hardest natural material on Earth.
Exceptional clarity, colorless grade, and flawless cuts make diamonds the top-tier gem in both emotional and financial value.
May – Emerald
Vivid and full of life, emerald represents renewal and love.
Fine Colombian emeralds with intense green color and minimal inclusions can exceed even diamonds in value per carat.
Their rarity and unmistakable color make emeralds one of the world’s most desirable gemstones.
June – Alexandrite / Pearl
Alexandrite is one of nature’s greatest miracles—a gemstone that changes color under different light sources.
It shifts from green in daylight to red under incandescent light, making it extraordinarily rare.
Natural pearls also hold prestige as timeless symbols of purity and grace, especially in high-end jewelry collections.
Its extraordinary rarity makes Alexandrite one of the most expensive and fascinating birthstones ever discovered.
July – Ruby
Few gems rival the passion of ruby.
The finest examples—known as pigeon blood rubies from Myanmar—are among the world’s most valuable stones, often surpassing diamonds in price per carat.
Their deep red brilliance and rarity make ruby the ultimate birthstone of power and devotion.
August – Spinel / Peridot
Spinel, once mistaken for ruby, is now recognized as a gemstone of remarkable brilliance and rarity.
Red spinels are particularly prized, while peridot adds a softer, golden-green charm.
Both gems symbolize warmth and positivity, perfect for late-summer elegance.
September – Sapphire
The sapphire, especially from Kashmir, reigns as one of the most sought-after gems.
Its velvety royal blue hue and high durability make it both luxurious and lasting.
The rare Padparadscha sapphire, with its pink-orange glow, is considered one of the rarest birthstones on Earth.
October – Black Opal / Tourmaline
Black opal from Lightning Ridge, Australia, displays a mesmerizing “play-of-color” — vivid flashes of blue, green, and red within a dark body tone.
Similarly, tourmaline offers a rainbow of colors, with the neon-bright Paraiba tourmaline ranking among the most expensive gemstones of modern times.
November – Imperial Topaz
The golden to pinkish-orange tones of Imperial Topaz make it November’s luxury gem.
Sourced mainly from Brazil’s Ouro Preto mines, it shines with warm sophistication.
Collectors cherish it for its rarity and natural brilliance that evokes sunlight in crystal form.
December – Tanzanite / Blue Topaz
Tanzanite is one of the world’s rarest gemstones, found only in a single region near Mount Kilimanjaro in Tanzania.
Its vivid violet-blue hue and limited availability make it highly collectible.
Blue topaz, meanwhile, is an elegant and affordable December birthstone known for its radiant cool tone.
Final Thoughts
From diamond’s eternal sparkle to ruby’s fiery brilliance, every birthstone holds its own kind of luxury.
Some—like alexandrite, emerald, and sapphire—are among the rarest gemstones in the world, while others such as amethyst and peridot offer beauty that’s more accessible yet equally meaningful.
Together, they reveal how nature turns time, pressure, and light into art — the true magic behind every gemstone.
