100% of what you see is natural nacre. The polymer is optically clear and nothing else has been added. The nacre has been crushed and separated by granual size. The impurities removed and reassembled in the M3 matrix with a small percentage of an advanced precious polymer; made in the USA.
The result is not just beautiful:
Strong, no ring core needed
Finished products will be almost unbreakable and will not chip or break if dropped from a reasonable height or normal use
Heat safe to over 300° f.
Available in Natural White Mother of Pearl or Natural Green Abalone.
