Rubies are indeed lovable but most of the people are not aware of the fact that rubies as well as sapphires are the member of corundum gem family. There are many factors which provide the reason to call a ruby technically as red sapphire. Isn’t it interesting that outside the color red every other sapphire like pink, red or green sapphire is referred as sapphire.
There are different ranges of color available in rubies and they are from pale pinkish red to dark reddish-brown and most of them can be mistaken for garnet. Their prices depend mostly on their color, cutting, transparency, and settings.
Ruby that I have is medium pinkish-red that has very good clarity and transparency. It was tensely set in the ring to view the stone from all the angles. If you view that from top, it would appear redder in color and bit silky as well and when you will view it from the side, it appears pinkish and feels entirely transparent.

A wide range of gemstones is consisted of minerals with a crystal like structure but we must keep in mind that all gems are not gemstones as they have an organic origin. They take their shape because of biological processes that can be animals or plants as well.
These organic gems are not found in a wide range but they include some usual varieties that are considered very important in the gem business. Amber, coral, jet, ivory and pearl are some member of this organic gem family.
Amber is considered as the fossilized toughen organic substance of the pine tree that came into being almost 50 million years back. The use of amber in jewelry, religious objects and amulets is as old as hills; it has been used in these things since prehistoric times. There is addition of insects, plants or pyrites in the pieces of amber which are considered the most prized. Kaliningrad in Russia is the place where the largest deposits of amber are found in the world. There are also large reserves of the amber in the seabed of the Baltic.
