Sapphire heating is a natural-inspired process used to improve a gemstone's color and clarity.In the earth, sapphires are formed under intense heat and pressure; heating labs simply replicate these conditions in a controlled environment.

By precisely warming the stones to specific temperatures, trapped microscopic inclusions dissolve, making the sapphire appear clearer.It also intensifies the vividness of the color.Because it mimics nature without adding chemicals or dyes, it is a globally accepted industry standard that ensures a beautiful, stable, and durable luxury gemstone.

Unheated sapphires are exactly as nature created them. Mined, cut, and polished without any extra heat, they represent less than 1% of all gemstones. Collectors prize them for their purity and rarity.

Heated sapphires are gently heated to reveal their full potential. This industry-standard process dissolves microscopic inclusions toimprove clarity and deepen color. The result is a vibrant, stable, and more accessible gemstone that showcases the brilliant "classic" look preferred for luxury jewelry.
