At the previous HK Sept Jewelry Show, I saw a variety Chocolate Pearls displayed at PARAS PEARLS, a company based in Kobe, Japan.
The color and quality was surprisingly nice, and they said the technique used by them was a mixture of radiation and heat treatment.
I bought some Chocolate pearls from PARAS PEARLS (Mr. Nirmam) at a reasonably justified price.
I believe Chocolate pearls are in fashion right now, and they will remain in trend for sometime due to its limited supply.
I wanted to share this information with all of you.
I think all of you who are interested in such pearls should contact this company :
nirmam@sanynet.ne.jp or 81-78-2316170
