Emeralds have captivated humanity for over 4,000 years. Cleopatra was famously obsessed with emeralds, and the ancient Egyptians associated the stone with fertility and rebirth. The finest emeralds have been sourced from Colombia for centuries.
Unlike most gemstones, inclusions are expected and accepted in emeralds — the trade calls them "jardin" (garden). A completely flawless emerald is extraordinarily rare and would be viewed with suspicion. The most valued emeralds display a vivid, saturated green with a slightly bluish undertone.
Emeralds are a variety of beryl, like aquamarine, with a hardness of 7.5-8 Mohs. However, their characteristic inclusions can make them more susceptible to chipping, so protective settings (bezel or halo) are recommended for rings.
Emeralds pair magnificently with yellow gold — a classic combination seen in jewellery throughout history. For a modern look, platinum or white gold creates a striking contrast. Emerald cut diamonds complement emerald gemstones beautifully in multi-stone designs.
The May birthstone is the emerald — the most prized green gemstone, belonging to the beryl mineral family. Emeralds symbolise rebirth, love, and wisdom, and have been treasured for over 4,000 years.
Fine emeralds are rarer than diamonds. The combination of vivid green colour, good clarity (for an emerald), and size above 1 carat is exceptionally uncommon. Colombian emeralds with the most sought-after bluish-green hue command the highest prices.
Emeralds have a hardness of 7.5-8 Mohs but their natural inclusions can make them more vulnerable to impact than their hardness suggests. A bezel or halo setting provides excellent protection for daily wear.
