Gem Stone King

Gem Stone King Gem Stone King is a leading online jewelry company. Everything we sell is of the highest quality and mainly manufactured in the United States.

With a family legacy exceeding a century in the diamond industry, we offer fine jewelry directly to consumers. 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, Israel, and Thailand. Nir 's father, Charlie Hollander, moved to Israel in 1966 from where he exported Diamonds all over the world selling to jewelry stores. Fifteen years ago he started the Charles Hollander Collection producing prestigious objects made out of gold and diamonds. The Internet changed all that. 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 began selling our jewelry on E-bay where we earned a customer satisfaction rating of 99.5% over more than 186,000 transactions. Today we are expanding our services on our own website. 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. 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. To all of you, from all of us at Gem Stone King - Thank you and Happy Shopping! Nir Hollander
