★★★★★★★


This masterpiece features sapphire, the birthstone for September, and fully captures the charm of unheated sapphire.
Vietnamese sapphires shine beautifully with their unique silky pink, subtle purple and orange sparkles.
This sapphire, which has achieved beautiful color despite not being heated, is a symbol of exquisite balance and harmony with the mysteries of nature.
Please enjoy its beauty and rarity in your hands.

Sapphires are made from the same mineral corundum as rubies, and are the same except for the important element of color; any corundum other than red is called sapphire.
Corundum, a crystalline aluminum oxide, is mined primarily from placer deposits and, more rarely, from bedrock deposits just below the earth's surface.
It is also an "arochromatic" gemstone, meaning its color is determined by trace elements such as iron and titanium.
