Imitation stones

A quality ruby is extremely valuable. Many different materials are used to create imitations of this truly precious stone. A few examples include: red glass, red tourmaline, almandine garnet, red spinel, etc. Of course traders of imitation rubies will not want to tell you what material they are really made of and just sell you the imitation for a real price. To make sure we only offer quality rubies we buy our stones at authorized traders. This way we are able to sell you only the quality stones you are looking for.
One may recognize a quality ruby by its intense colour and lack of impurities. The quality stone is a dove’s blood red and has a lively shimmer.

Cut

Rubies may appear in any number of cuts. The most common cut for rubies is the faceted cut. In addition to this cut, however, there are many more options ranging from oval facetted cuts to cabochons with a star-like effect in the stone.
