About us

The Diamond Connoisseur Company was created by Perry Chen whose family has been in the Diamond cutting and Jewelry manufacturing industry for generations.

TDC’s vision is to create the highest quality handmade jewelry, using age old techniques Mr Chen acquired over the years.

Mr Chen personally works with each client and supervises the production of every piece from design to quality control after completion.

TDC has satisfied clients in over 15 countries and throughout the US. We are experienced in working long distance using HD videos and photos to showcase our diamond and gemstone selection to clients.

TDC is located in the heart of NYC and the center of the Diamond district on Fifth Ave and 47th street. TDC is a proud member of the DDC (Diamond Dealers Club) in NYC.
