About Us

Christina Termine, jewelry designer and owner of Diamonds On The Key loves sharing her 35 years of experience and knowledge in the international fine jewelry arena with each and every client with the goal of providing both an education in diamonds and gemstones, while offering the very best price. Christina aims to make every customer feel confident and informed in their jewelry purchase, while receiving the highest level of personalized service.

Christina received her Graduate Diamonds Diploma from the Gemological Institute of America (GIA), which is regarded as the world’s foremost authority in gemology and she insists on buying and selling only GIA certified diamonds. When meeting with Christina in her private jewelry salon, located in Miami, or conversing with her by phone, each client is professionally guided through the diamond selection process, in order to choose with confidence the perfect diamond or piece of jewelry they desire.

“Forming a reliable and trusting bond with your jeweler is just as significant as the trust and service provided by your doctor, real estate agent, lawyer or financial advisor” states Christina “and that bond is what I aim to build with each customer for a lifetime”.
