About Us

UMA ENTERPRISES is a group of the companies 6 years since 2011. Our 2 branches, first those I present, UMA ENTERPRISES and the second is GR GEMS & JEWELRY INC; Twenty-four years ago, since 1993, in the USA, Los Angeles (CALIFORNIA). We are dealing with all kinds of gemstones, diamond jewelry, silver jewelry in India and any type of precious and semi-precious stones, diamond jewelry, and silver jewelry in the United States. We are dealing in following world famous precious stones and Jewellery:


Emerald is the most famous member of the beryl family. Legends have endowed the wearer with the ability to predict the future when the emerald has been placed under the tongue, as well as revealing the truth and being protected from evil spells. On the other hand, Emerald was believed to cure diseases such as cholera and malaria. It was believed that the wearing of an emerald revealed the truth or falsehood of a lover's oath and made an eloquent orator.

We differ on the degree of green that makes one stone an emerald and another stone a less-expensive green beryl. Most gemologists, gemological laboratories, and colored stone dealers call a stone green beryl when its color is “too light” for it to be classified as emerald. Even among that group, however, there’s a difference of opinion about what’s considered “too light.”


Rubies can command the highest price on each colored stone. This makes ruby one of the most important gemstones of the colorful stone market. In its purest form, mineral corundum is colorless. The trace elements that form part of the crystal structure of the mineral cause variations in its color. Chromium is the trace element that causes the red color of ruby.


Sapphire is one of the Big 3 of jewelry colored gemstones—the other two are ruby and emerald. A durable stone that’s designated as a birthstone for September, it captures jewelry buyers with its practicality and aura of romance.
