Proof of Our Pearl Quality

Pearl Oasis offers the largest size selection of Hanadama Grade pearl necklaces of any on-line store. Each of our Hanadama pearl necklaces has been tested and certified by the Japan Pearl Science Laboratory (JPSL), Tokyo, Japan. They are the top two percent in quality of all Japanese pearls. Japan Pearl Science Laboratory is a world-recognized authority of pearl quality. Each Hanadama pearl necklace comes with the JPSL certificate at no extra cost. Hanadama Grade pearls come to us in a temporary strand from Japan and the necklace is made in the USA. Our designer individually knot between each pearl and adds our custom designed 18K gold, double-sided clasps. You have the choice of white or yellow gold.

Each JPSL certificate is unique to each strand of pearls and has a unique certificate number. The certificate is laminated in plastic and comes in a portfolio with the Japan Pearl Science Laboratory logo.

When you look at the details page for a given Hanadama pearl necklace, you will see a picture of the actual pearl strand and a picture of the actual certificate with its unique number that will be delivered with your order. A sample of the certificate can be seen below.
