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.

Gemselect is o.k the prices are pretty good, but the shipping prices really suck, one time I order from them and order got lost or never came, but they were good about fixing the problem and rectifying the situation, the stones and good, and the ones that come in the mail, look just as pictured on the website, or all it's not bad and its were I go to get my stones.

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
