About Us

R.K. Kalati company is a second generation family business passed on from father to son. The integrity practiced in their business is so strong that they put their family name and stamp on it.

Our principle owner and traveling salesmen travel around the United States buying estate diamonds and jewelry. One of our essential business policies are keeping our stores happy, and helping them seal deals. After all, we rely primarily on repeat customers and word of mouth.  As a second generation jeweler, the company owner has been born and raised in the industry. He started working in the business when he was only 18. The journeys he has been on have left him most of all with two things: a strong eye for pricing diamonds & estate jewelry; and the strong belief that only a good clean hand shake will take the business to the next generation. We hopes to pass on the name which has become synonymous with honesty, trust and fairness. Out motto is “Able, willing and ready to beat any legitimate offer by 10%”.

We know that in the diamond industry paying the highest prices is not enough. A customer selling a diamond needs to feel safe. To ensure this, we help your store offers several alternatives to shipping valuables. We offer phone consultations and price quotes based on an existing GIA Certificate for diamonds.  For estates in excess of $35,000 we can make personal visits to your location, to help meet with your clients and seal the deal. And of course, those located in NY can call for an appointment.

Some of our specialties include buying loose diamonds and engagement rings featuring old mine cuts, large off color diamonds, Marquise, Pear shapes and round diamonds over 2 carats. We also buy signed estate jewelry as well as platinum and French diamond jewelry.

Our owner is a GIA Diamond Graduate & a member of the New York Diamond Dealers Club. The company is member to the Jewelers Board of Trade, Rapaport trading group, International Watch and Jewelry Guild, and the National Association of Jewelry Appraisers.

Please see our testimonials, we think they speak for themselves. We look forward to adding your comments and testimony to our long list of happy clients. Price quotes are free and confidential. Upload your diamond information now and we will give you a call!
