Clarity Report

Nature is rarely perfect, so it is very rare to find a diamond that is completely pure and free of inclusions. Inclusions are minerals or crystals trapped within the stone at the time of its formation. Without ten-power magnification, you may never see these tiny inclusions, but they are the fingerprint that makes each diamond unique.

This is Jackie D. I just worked with Jeff on a pendant and earrings for a policyholder of mine and they turned out amazing! The stones were so vibrant and my policyholder just loves them! I always call Jeff for anything opals!

I took my wedding ring to have a stone replaced. The owner gave me a receipt with the price. When I returned he added $50 to the price before returning my ring. Three days later the stone fell out of the ring. The owner became very defensive and belligerent when I returned with the ring. Not a reputable business, don't waste your time here.

I can always count on Shyam to come through. He was able to recall my wedding band specs and replace it after I had not talked to him in over 10 years. We've never been disappointed. He's my lifetime jeweler, even when I am no longer in Missouri.

Their services are very reasonably priced and the turnaround was very fast. He charged me $25 to have my ring sized vs $40 at a place down the street. He also had it done within a few hours.

My wife and I have been here multiple times and have always found the service, quality, and price to be excellent. The owner is extremely knowledgeable and fair. After several attempts to correct an engagement ring issue (that was made elsewhere) these guys were able to fix it, when several others could not.

I needed to get my necklace fixed since the chain broke, and so I took it to International Diamond. Shyam and his wife (the owners) looked at the necklace and provided me with several options. I decided to get rid of the old chain and have them use a new chain link and clasp. Shyam said to come back in two days, and voil! I was extremely pleased for a number of reasons: 1. Shyam and his wife are incredibly benevolent and were very helpful in finding a solution for fixing my necklace. 2.

In addition to being helpful and knowledgeable, Shyam and his wife were also very honest. They told me the prices upfront and gave their honest suggestions for what to do with my necklace. Not once during the entire process did I feel like they were trying to take advantage. 3. Price wise, it was very justified and more than fair. You won't find a better jeweler in St. Louis.

In conclusion, Shyam and his wife are the best. Lifesavers, if you will. I'm recommending them to all of my friends and definitely plan on coming back in the future. Give them a try. You won't be disappointed.
