A Leading New York City bank

To appraise such a wide variety of precious and semi-precious mounted and loose stones would have been very difficult without your help. Specifically, your suggestion on how to segregate the inventory in order to maximize perceived value had a substantial impact on the final sell price.


Christopher G. Ellis, President: Consensus Advisors LLC

SimplexDiam Inc. played a number of significant roles during the valuation phase and eventual auction of the $70 million of LID inventory. Their efforts contributed to a greater than expected recovery from the sale of the inventory. We value SimplexDiam Inc's input and would readily work again with such an industrious team.


Bill Boyajian, Former President of GIA

We have been working with SimplexDiam Inc. and the Madhvani family for some time, and are impressed with their industry knowledge and ability to work on many different creative projects. They are true pioneers and we regard their contributions highly.

Jim Rodriguez, Owner: Diamond Exchange

We have been customers of SimplexDiam Inc. for many years and have always been impressed by the value of their jewelry. There is no doubt that they are a rare find.
