【Available 9/6 at 10 PM】 Tanzanian Windsor Sapphire (Purple Sapphire) 0.277ct Loose Gemstone

Sapphire is a world-famous gemstone that needs no introduction. Mineralogically, it is the same as ruby—corundum—but all corundum that is not red is called sapphire. It is known for its diverse color variations, including blue, pink, yellow, and green. This is a sapphire from Windsor, Tanzania. Windsor sapphires are not widely circulated in the market and are known among gem collectors as a specific locality. Tanzania is recognized as one of the world's leading gemstone-producing regions, yielding many beautiful stones such as spinel and tanzanite, and it also produces attractive sapphire crystals.
