Heated Sapphire 1.84CT
Origin Madagascar
Certification : Available
Madagascar sapphires are known for their high quality and size, and for the variety of colors they come in. Here are some features of Madagascar sapphires:
Color
Madagascar sapphires can be found in a variety of colors, including blue, pink, yellow, green, white, and orange. The orange variety, known as Padparadscha, is the rarest and most expensive.
Growth zoning
Madagascar sapphires are known for their complex angular growth zoning, which can create sharp angular structures or an iridescent effect.
Color zoning
Madagascar sapphires can have striking color zoning, with thin, deep blue zones surrounded by lighter colored clouds.
Growth tubes
Madagascar sapphires often contain growth tubes, which can be small and single or clustered together.
Deposit
Madagascar sapphires are found in altered marble and limestone silicates, known as "skarn". A large sapphire deposit was discovered in Madagascar in 1998, which led to a rush of people to the island in search of gemstones.
Heat treatment from lower to higher temperatures can have a significant impact on the color of metamorphic blue sapphires from Madagascar. In our study, temperatures between 800 and 1100°C in air lightened the blue color, while higher temperatures, which can dissolve rutile, created deeper, more saturated blues
