【9/12 22:00 Release】 Tanzanian Windsor Sapphire (Color Change Sapphire) 0.261ct Loose Gemstone

Sapphire, a gemstone that needs no introduction. Mineralogically, it is the same as ruby, belonging to the corundum family, but any 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 distributed in the market and are known among gemstone collectors as a notable origin. Tanzania is known as one of the world's leading gemstone-producing regions, yielding many beautiful gems such as spinel and tanzanite, and it also produces charming sapphire crystals. This piece is a color-change variety.
