Blue Star Sapphires
Blue gemstones never go out of fashion and one of the most popular blue gem types is sapphire. Blue 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. Blue star sapphire is an excellent men's jewelry gemstone. 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". Sapphire is seen as the guardian of love. When given as a gift it enhances love and tunes your psyches to one another. Also, it has been used to banish envy and jealousy as well as promote fidelity in marriage. Shop for natural blue star sapphire gemstones from a range of sizes. The blue sapphire gemstones in stock include large blue star sapphires and small blue sapphire gems.

finally bought the last rock to complete my ring idea; needed another white one after giving the big diamond to my daughter. a diamond that size is out of my retired-school-teacher budget, so i bought a white zircon. went back to the same place that i got my loose sapphire-- great selection, good prices, good delivery!

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
