Product Facts
We make all of our gemstones!
We Do It All!


Starting with the raw chemicals, all the way through the crystallization and continuing on through the cutting, faceting, final polishing, and finally placing the gem in a piece of jewelry, we really do it ALL!!

We think there is no other company on Earth that does the complete process as we do!

We make only SOLID GOLD JEWELRY - NO GOLD PLATE OR GOLD FILLED.
GOLD FILLED DOES NOT MEAN FILLED WITH GOLD.
It is a deceptive term meaning very much the same as heavy gold plate.

We make more varieties of Man-Made Gemstones than any other company on Earth.

WE MAKE MAN-MADE RUBIES AND SAPPHIRES.

Man-Made means chemically and physically identical to something that nature made, i.e., our Shelby "RUBIES and SAPPHIRES" are chemically & physically the same as those dug from the ground, with this exception: since we made them, most are nearly flawless, because we control the ingredients and cooking temperature.
It is rare to find a flawless natural Ruby.
We also make the very rare (in nature) fancy colored sapphires such as: Golden, Pink Champagne, Aqua Blue and Yellow, besides the extremely popular traditional Dark Blue Sapphire.

We make simulated DIAMOND, ALEXANDRITE, AMETHYST, EMERALD, BLUE TOPAZ, AQUAMARINE, GARNET, BLUE ZIRCON, ROSE SAPPHIRE.


Shelby “Diamond Encores™”, while being chemically different, are visually indistinguishable from genuine diamonds. There is no possible way for an unaided eye to visually tell the difference between an "Encore" and a fine quality genuine Diamond! The only natural substance able to scratch one of our “diamonds” is a genuine diamond or sapphire.

Shelby “EMERALDS” are chemically different from genuine emeralds.  Shelby “EMERALDS” look like natural emeralds, but are about 1.4 times harder and considerably tougher than fragile natural emeralds.

We think they are much better than natural emeralds.

Diamond Encores™ are guaranteed (to the original recipient) against scratching and permanent discoloration under normal wear in their original mounting. If a stone gets scratched or permanently discolored, we will replace it with one of similar weight and color, free of charge.

(In 42+ years we have never had a stone discolor.)

We have a money-back guarantee. After you receive your jewelry, examine it at no risk. If you are not satisfied, return it undamaged within 15 days, and we will immediately refund your money ...... with no questions asked.

Shelby Gemstones™ are much less expensive than their natural counterparts. Shelby imitation Emeralds are $190 per carat and Shelby Man-Made Rubies and Sapphires are $185 per carat.

In most cases, the price of a Shelby Gemstone™
is about 1- 2% of the price of a natural stone.

For instance: A one carat "Shelby Diamond Encore" sells for $175, while a one carat "flawless", D color natural diamond sells at wholesale for over $29,000!
