A Tradition Worth Keeping
The custom of associating gemstones with months of the year stretches back to antiquity and was formalised into the modern birthstone list in the early twentieth century. Whether chosen for sentiment, symbolism, or simply colour, a birthstone is one of the most personal gifts in the gem world. Here is our month-by-month guide.
The Twelve Months
- January — Garnet: Far more than deep red, garnets range from vivid green tsavorite to orange spessartine. A durable, brilliant, and underrated family of stones.
- February — Amethyst: The royal purple variety of quartz, prized since antiquity. Affordable in fine quality and available in spectacular specimen clusters.
- March — Aquamarine: The serene sea-blue beryl, cousin to emerald. Clean, bright, and beautifully suited to large, eye-clean cuts.
- April — Diamond: The hardest natural material and the classic symbol of enduring brilliance. Increasingly chosen with attention to ethical sourcing.
- May — Emerald: The lush green beryl of Colombia and Zambia. Its inclusions, called the "jardin," are part of its identity and charm.
- June — Pearl & Alexandrite: Pearls offer organic elegance, while rare colour-change alexandrite shifts from green in daylight to red under incandescent light.
- July — Ruby: The "king of gems." The finest, from Burma and Mozambique, glow with a saturated red the trade calls Pigeon's Blood.
- August — Peridot: A bright, lively olive-green, formed in the earth's mantle and even found in meteorites.
- September — Sapphire: Beyond classic blue, sapphire comes in every colour but red, including the prized pink-orange padparadscha.
- October — Opal & Tourmaline: Opal flashes a play-of-colour found in no other gem, while tourmaline spans the widest colour range of any mineral, including electric Paraíba.
- November — Topaz & Citrine: Warm, golden, and abundant in larger sizes — generous, sunny stones for the season.
- December — Tanzanite, Zircon & Turquoise: Tanzanite's violet-blue, found only in Tanzania, has become a modern favourite alongside fiery blue zircon.
Choosing a Fine Birthstone
Whatever the month, the same principles of quality apply: look for pleasing colour first, then clarity, cut and carat weight. Insist on disclosure of any treatment, and favour certified stones for higher-value purchases. A birthstone chosen with care becomes a keepsake that carries meaning for a lifetime.
