After 12 years Karen left KRDiamonds and created K. Rosengart where her focus continues to be catering to designers and manufacturers.

Hear from our Clients

K. Rosengart has phenomenal, ideal-cut diamond melee that they sell both to the trade AND to the hobbyists and consumers without onerous minimum order requirements. The melee I have gotten from K. Rosengart has been top quality and better priced than what I could get even from manufacturers in China.
