Excelsior Diamonds began in the early 1980's as a Rough Diamond Importer and Diamond Manufacturer as well as a Wholesaler to the trade. Several years after his Father started the company, Greg was fortunate enough to work with Ostalkiewicz Diamond Importers; one of the largest Independant Diamond Importers and Manufacturing Jewelers in the US at that time, with wholesale and retail outlets in New England and the Southeast. Along this journey, Greg also became a Graduate Gemologist through the Gemological Institute of America, the worlds foremost authority on Diamonds/Gemstones and the Laboratory that invented diamond grading. Now, over 31yrs later, Excelsior Diamonds continues to fill Diamond and Jewelry requests at close to wholesale prices for friends, family and retail consumers. As Gold & Diamond prices have continued to rise to near record price levels, a new service has emerged at Excelsior Diamonds - Due to growing demand from consumers looking to sell their old and unwanted diamond jewelry and receive a fair value, Excelsior Diamonds now pays top dollar for Gold, Platinum & Diamonds in any condition, even if it's broken! Excelsior Diamonds is now the best place to both Buy & Sell Diamond Jewelry. Thank you to all our customers!
