This page is exclusively for winners of the lottery sale.
Sapphire is a well-known and renowned gemstone. Although its mineral is corundum, like ruby, all corundums that are not red are called sapphires. With a hardness of 9, sapphire is the second hardest gemstone after diamond, and its high toughness and stability make it an easy gem to care for.
