HANADAMA Japanese Akoya Pearl Necklace
The Pearl Science Laboratory's certifications are graded to the strictest standards, using x-rays, magnification, and optical fibers. In order for a pearl necklace to be graded as a Hanadama necklace it must have a strong cultivation, high luster, clean surface, round shape, and have at least .6mm nacre thickness. American Pearl's Hanadama strands exceed minimum nacre standards on average and offer the best prices for these gems. Each certificate that will accompany your Hanadama necklace is an authentic numbered report from the Pearl Science Laboratory.
