We are always looking forward to providing you with exceptional guidance and design assistance in making any beautiful piece of jewelry and especially in designing your custom Ultimate Engagement Ring, making it truly that special symbol of your lifelong bond.Ultimate Diamond was first started by the late Mr. Kung Sr. when he brought his family and burgeoning pearl business over to America from Taiwan in 1959. Mr. Kung Sr. established himself in the industry by keeping to his principles of quality, service, and expedience in everything Ultimate Diamond does. Through this practice he grew the business steadily over the decades until Mr. Kung (Son of Mr. Kung Sr.) took over the business in the 1980's. Mr. Kung, building on everything his father bestowed upon and taught him, redefined the diamond market for consumers by being one of the first to exclusively offer and sell G.I.A. Verified Diamonds. G.I.A. Verified Diamonds are those diamonds that have been submitted to the Gemological Institute of America for verification. The Gemological Institute of America (G.I.A.) is the foremost trusted authority for diamond grading in the world and stands alone in their expertise.
