The Mervis name has thrived in the diamond industry for almost a century. Today, generations later, the Mervis family still owns the business Morris Mervis founded, now called Mervis Diamond Importers. Unlike other internet shopping services where you are on your own in cyberspace, Mervis Diamond Importers and e-diamonds.com have personal shoppers to assist you intellegently and compassionately through every aspect of your purchase.
