This sapphire weighs 8.07 carats, which is approximately 1.61 grams. The elongated cut stone is just over one centimeter long, just under one centimeter wide, and nearly 8 millimeters deep. This makes it ideal for use in rings or bracelets. It is also suitable for a simple necklace.
This sapphire shines as a single stone in a piece of jewelry, but its beauty is also enhanced when combined with other sapphires, crystals, or small diamonds. With special design, your jeweler can further increase its value.
Origin: Madagascar – Home to High-Quality Gemstones
The stone originates from Madagascar, one of the richest sources of gemstones in the world. Since the 1990s, gemstones have been mined here, including sapphires, rubies, and spinels in the highest quality. Sapphires in all colors of the rainbow are found in Madagascar and are mined in numerous small and large areas – mostly by hand, with pickaxe and shovel.
Treatment
The certificate notes “Signs of a thermal treatment,” which suggests that the stone has been heat-treated. This treatment is very common and standard for sapphires. The heating process, also known as “firing,” is a specialized science. The artisans who perform the treatments keep their "recipes" strictly secret. The purpose of heating is to permanently enhance the color and clarity of the stone.
