Gold & Diamond Buyer
We are round Gold & Diamond Buyers because a round round cut diamond is the most brilliant of all the diamond shapes. Brilliance (sparkle) is dependent on the proportions calculated by Tolkowsky way back in 1909. These ideal proportions have been proven to reflect and disperse light in the most effective way and that is why the round shaped diamond enjoys the most demand.

Large Pear Diamond Buyer
Pear shaped diamonds may not be the most brilliant of all the shapes but the teardrop outline lends itself to many designs where a round will just not flow. As a pear shaped Gold & Diamond Buyer I am pleased that the market price has gone up significantly over the past decade.

Large Square Diamond Buyer
Whether you have a radiant cut, princess cut, Asscher cut, emerald cut or other square/rectangular shaped diamond fine examples have hit very high prices. Some consider these shapes the most elegant of all the shapes. Historically these shapes have not enjoyed high market value compared to rounds. Thankfully, many retail buyers have embraced these shapes and therefore market values have increased.
