About Us

International Diamond Inc has been serving residents in the greater St. Louis area from it's location in Clayton, Missouri since 1994. We understand that the jewelry industry is a loyalty retail business, and that is why customer satisfaction is our number one goal. At International Diamond we feel that word-of-mouth is still the best form of advertising available.


Owner Shyam Katta is known throughout the St. Louis area for his skills in grading diamonds as well as his available stone selection. That is why we know that if you come in to International Diamond Inc you will answer the question that comes with every purchase, "Are you Happy?" with a resounding, "Yes."
