Natural sapphires in blue, pink, yellow and fancy colours — at auction and for sale.
Sapphire is gem-quality corundum in every colour except red. Blue sapphires from Sri Lanka, Madagascar, Burma and Kashmir are among the most sought-after gemstones in the world, while fancy sapphires offer an extraordinary spectrum of pinks, yellows, purples and greens. Every sapphire on Gem Lot Auction lists its origin, weight and a structured treatment disclosure — including whether the stone shows indications of heating — so you can bid with confidence.
