this kind of all-over mosaic of M. O. P. shell pieces securely stuck onto a shaped backing of darker shell or plastic and beautifully polished is very characteristic of the jewellery components produced in the Philippines from natural materials in around 70/80s onwards and the value doesn't depend on the age -its a craft they mastered well, and some of the design ideas may have been adapted subsequently by the chinese costume jewellery industry.
Thankyou Stephany for the info. The prices are super well made and are mop all the way round and really shimmery.
Thanks again
