coloured gemstone
At GIOIA Fine Jewellery, we offer some of the world’s rarest and most exquisite coloured gemstones, carefully selected from renowned global mines. From the vibrant Paraiba tourmalines to lilac spinels, our collection features unique stones like Colombian emeralds, Sri Lankan sapphires, and Mozambique rubies, all chosen for their brilliance, rarity, and exceptional quality.
The value of coloured gemstones depends on factors such as colour intensity, origin, clarity, cut, and carat weight. Stones like neon Paraiba tourmalines and unheated Burma sapphires to Sri Lanka are highly prized due to their rarity and natural beauty. Colour remains the most important feature, with stones from specific regions, such as Burma for ruby and Colombia for emeralds, often being more sought after.
At GIOIA, we focus on natural, unheated gemstones, ensuring each stone’s authenticity and origin. We also provide independent certification to verify the quality and value of every gem. Our collection also includes rising gemstones like tanzanite, allowing for bespoke designs that range from classic to contemporary.
