October Birthstones
Opal and tourmaline are the birthstones for October, providing choices in every possible color. More than any other gem, each opal is distinctly an individual. No other stone has as rich and varied a folklore. Opals are also the most delicate gems commonly worn. They require special care to ensure their health and longevity.

Tourmaline derives from the Sinhalese term "turamali", which translates as "stone of mixed colors". The very name refers to the unique spectrum of colors displayed by this gemstone, which is second to none in the realm of precious stones. One of the most versatile of gemstones, tourmaline is available in every color, from colorless to black. It can show every tone from pastel to dark, and can exhibit various colors in the same stone.

The astrological stone for Scorpio is beryl. Beryl is one of the most important mineral groups and also one of the biggest gemstone groups. Although the mineral is abundant, it rarely occurs in transparent gem-quality material. Transparent gem-quality beryl is referred to as 'precious beryl'. The most famous beryl gemstone is green emerald, followed by blue aquamarine. Golden beryl is not very well-known by the general public. Other popular beryl gems include pink 'morganite' and white, or colorless, 'goshenite'. Red beryl is the rarest variety of beryl and it is known in the trade as 'bixbite'.

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!

I'm always real pleased with this website, I don't think there is much you could do to make it any better. I wish the shipping charges were lower, but it is understandable.

This is a site that sources valuable and genuine stones forms around the world, with and honest and descriptive sections, as well as specs, and the option to have the gemstone collection one might purchased—certified! Price ranges vary, but are always affordable and always worth it, whether it’s a gift, or for a personal business.

I recently found a site on-line where you can purchase faceted gems. I made one purchase, and the day the gems arrived, I was so happy with them, that I immediately went back on-line and purchased four more gems! They look better "in person" than they do on the computer screen. I am making purchases for gifts.

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
