Black Star Sapphires
Black gemstones never go out of fashion and one of the most popular black gem types is sapphire. Black star sapphire is cut as cabochons to bring out the asterism (star effect). Star sapphires are best viewed under focused light, such as a flashlight. Black star sapphire is an excellent men's jewelry gemstone. The black star sapphires from Thailand are special in that they have golden stars. Sapphire has a hardness level of 9 on the Mohs scale, which makes it one of the most durable gems of all time. Sapphire is a form of corundum that occurs in almost every color. Red corundum is known as ruby. The name corundum comes from the ancient Sanskrit "kuruvindam", while the name "sapphire" comes from the Persian word "safir". Sapphires are seen as the guardians of love. When given as a gift they enhance love and tune your psyches to one another. Also, sapphires have been used to banish envy and jealousy as well as promote fidelity in marriage. Shop for natural black star sapphire gemstones from a range of sizes. The black sapphire gemstones in stock include huge black star sapphires and small black sapphire gems.

Size and Weight

Gems are always measured in Millimeter (mm)

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
