Effy's Precious Gems collection brings together the three most revered gemstones in fine jewelry: the ruby, the emerald and the blue sapphire. Known as the king of precious stones, ruby is the rarest and most valuable member of the corundum family, prized for its vivid red color and rich history dating back over 4,500 years. As the official July birthstone and traditional 40th anniversary gift, ruby jewelry remains one of the most sought-after gemstone gifts, such as a fine ruby ring, ruby earrings or statement ruby necklace. Emerald, the most celebrated member of the beryl family, offers a deep, verdant green prized for millennia, with fine emerald jewelry often featuring natural inclusions, known in the trade as the emerald's "Jardin," that add to its individual character and value. The emerald cut, named for this iconic gemstone, remains one of the most requested cuts in fine jewelry. And blue sapphire, the classic corundum gemstone beloved for its royal blue color and exceptional durability, is a brilliant choice for a sapphire engagement ring, sapphire pendant or sapphire tennis bracelet, rated among the hardest of all colored gemstones for lasting everyday wear. Each gemstone in our precious gems collection is available across every fine jewelry category, from rings and earrings to bracelets, necklaces and pendants, and is beautifully set in 14K yellow gold, white gold or rose gold. Whether you're searching for a ruby and diamond ring, an emerald cut emerald necklace, a blue sapphire bracelet or a meaningful fine jewelry gift featuring precious gemstones, Effy's Precious Gems collection offers the rarity, color and craftsmanship of the world's most iconic gemstones.
