Ruby is red corundum, all other varieties of corundum being referred to as sapphire. Corundum is the second hardest substance on the Mohs scale, with a rating of 9. It is this combination of excellent hardness and the rich color and silky shine that make fine ruby gems so valuable.
Rubies range in color from pinkish to orangey and purplish and brownish red, depending on the chromium and iron content of the stone. Most experts expect a medium to medium-dark color tone in a very good ruby gemstone.
The traditional sources for fine rubies are Burma and Thailand. Today we also find many affordable rubies coming from Africa and Madagascar.
A gemstone cabochon is cut with a highly polished rounded top with no faceting and a flat or slightly domed base. A cabochon may be cut into any shape, though oval is the most frequent. The term, "cabochon" comes from the French "caboche", meaning small dome. Cabochon is often shortened to "cab" by gem enthusiasts.
Ruby cabochons include star ruby. They are inexpensive and attractive, and available in large sizes. Ruby cabs make stunning necklace pendants, rings, bracelets, earrings and more.

It was easy to find the kind of stone I was looking for in the price range I preferred.
The site it's self looks fairly plain and simple but the wide variety of stones with high quality photos and price ranges made finding a beautiful stone in my price range was extremely easy.
I love collecting Gems and Gemselect is my go to place to get them. I have never been dissatisfied with any of my orders. I also love the information that they give for each gem.
I was looking for gemstones to use for making jewelry for birthday gifts. It was east to find what i needed with the birthstone information and quick and easy to locate gems. Ive never bought gems from anywhere else. This is a good site
I fell in love with my beautiful blue turquoise stone. When I received the stone it is more beautiful than the picture showed. I can hardly wait to design my pendant!)
I was looking for a gemstone called Sphene/Titanite and found it on GemSelect. They had many gems to choose from and had good prices. I received my order a little later than expected but given that it's coming from overseas I wasn't too worried. The 2 gems I received are beautiful. I have to say that I have no gem knowledge- I am a novice and I ordered the Sphene for healing purposes, so I am hoping they are real. I have no way of confirming if that is true. But they are beautiful!
I have ordered many many gems over the years from them and I am always VERY happy!! And if I wasn't they do accept returns which is a great peace of mind.
