Keepsake Diamonds Corp., located at the Commack Jewelry Exchange, is the first booth on the left when you walk in. This premier jewelry store provides customized engagement rings, tennis bracelets, necklaces, gold jewelry, silver jewelry, and jewelry for special occasions. They also buy gold, silver, and diamonds. Customers describe wonderful experiences with the jeweler, John, who greets everyone with a smile and a friendly welcome. He is incredibly helpful, honest, very knowledgeable, and personable. He is a straight shooter with quality items. One customer went in for two wedding rings and found beautiful ones to choose from, noting the price was half of what the big chains wanted to charge. The rings came in fast with no stress. Another customer had sentimental items, including a rope chain and cross, repaired. John knew exactly what to fix, took great care, and the items looked brand new. The prices are amazing, and customers were very happy with their purchases without feeling pressured. Many highly recommend this jeweler and will return for all future jewelry needs.
We were referred to John,we bought our wedding bands from him and Emmanuel were very helpful in finding me the perfect band,he is honest and caring…Best decision going to Keepsake! Thank you Penny & Bob

I went to 3 different other jewelers to sell a piece of silver and they gave me the highest offer…. A former jeweler friend weighed my piece and told me what a reasonable offer was…. they provided that exact $$$ figure…Highly recommend this place for selling.
