The story of Gem Stone King is the story that proves the saying that "the more things change, the more they remain the same". Today, Gem Stone King is a leading online jewelry company with over 300,000 Internet sales. While Internet technology is relatively new, the family that owns Gem Stone King has been in the diamond business for over 100 years.

Our president, Nir Hollander is a fourth generation diamond merchant. Nir’s great grandfather, Elyahu Holzer, started the business in 1903 in Antwerp, Belgium.

From these humble beginnings the family grew the diamond business with locations in New York, Belgium, Thailand and the USA. Nir 's father, Charlie Hollander exported Diamonds all over the world selling to jewelry stores. Fifteen years ago he started the Charles Hollander Collection.

The amazing power of the Internet made it possible for us to offer our fine merchandise directly to consumers. And because we buy gems direct from the source, we are able to offer low prices to match our high quality.

We are proud to offer our clientele a wide range of products including: beautiful polished diamonds, colored diamonds in a range of exciting colors (pink, rainbow-red, orange, yellow, blue and green), loose gemstones and fine designer jewelry. Our quality is unsurpassed and all of our collections cater to the latest fashion trends.

We have rings, earrings, bracelets and pendants with diamonds and semi-precious stones. Everything we sell is of the highest quality and every piece is brand new and mainly manufactured in the United States.
All diamonds sold by Gem Stone King are conflict free. We are only buying rough diamonds from authorized sources with a Kimberley certificate.

Our customers benefit because we are diamond wholesalers who can sell to them directly. Because we control the entire process from source to final product we control the costs and are able to maintain the highest quality and to pass savings to our customers.

With our old world values and traditions and our mastery of the most advanced Internet technologies, we truly offer our customers the best of both worlds.
