About Gendiat


  Who are we?

    Gendiat (General Diamond Trading Co.) diamond manufacturer was founded in 1969 in the city of Antwerp (Belgium) - the largest diamond trading center in the World. 

   Gendiat started as a diamond trading company, and has since evolved rapidly into a major manufacturing business, producing the finest diamonds from rough stones and supplying them to jewelry stores and auction houses across the world.  Our headquarters are located in the prestigious Diamond Club building, where the famous diamond exchange, founded in 1893, can be found.

  Our specialty lies in producing the finest cut diamonds, ranging from 0.50 carat to 7 carats, with the lowest price. The quality and the value of each diamond is guaranteed by a Belgian HRD (Hoge Raad voor Diamant - Diamond High Council) or American GIA (Gemological Institute of America) diamond certificate.

   HRD and GIA are both non-profit institutions which establishes standards for diamonds to be compared. For further safety, HRD seals each certified diamond in a plastic holder together with a microfilm of the certificate to prevent tampering.

  Our philosophy is to continue to provide the highest quality diamonds from our own factory located in Antwerp, Belgium, at the lowest wholesale prices you've ever seen.

We understand that purchasing a diamond is not a small endeavor.  We therefore commit ourselves to educate you about diamonds and provide you with the best service available through mail-order.

  We hope to be of service to you in the near future.


Why purchase a Gendiat diamond?

Unlike the current world of multi-national corporations, Gendiat is still a small family-owned business.  Each rough stone we get has been meticulously analyzed by myself, before being carefully crafted into a beautiful diamond by our experienced diamond cutters.  Our philosophy is that we rather sacrifice the size of the diamond for better proportions to ensure maximal brilliancy.   A slightly smaller diamond with excellent proportions will sparkle a lot more than a larger diamond with poor proportions.  

Hence, most of our diamonds have dimensions that are rated "Very good" or even "excellent" according to 3rd party graders such as GIA and HRD.  Furthermore, since we are manufacturers, you will get the lowest price possible.  Most big diamond sellers, whether they are retail or online stores, buy from people like us to sell it to you.

Our advice to our customers is always to educate yourself as much as possible regarding diamonds.  We encourage you to shop around and compare our prices with anyone else.

We also pride ourselves to assure your complete satisfaction.  That means not only will we provide you with first class customer service prior your purchase, but we will also ensure that the whole delivery process from Belgium to the US occurs smoothly.  Your package will be tracked by us as it is shipped to you by FedEx.

And if upon receipt of your diamond, you are not 100% satisfied with the diamond, you have a 7-day money back guarantee less shipping charges with no questions asked.

If you have any questions at all, please do not hesitate to call, fax, or email me directly.
