Pearls enthusiasts definitely knows what the best Akoya Pearls are, and they are called Hanadama. Hanadama, meaning “Flower Pearl”, represents the highest quality available in Japanese Akoya Pearls, certified by the Japan Pearl Science Laboratory.
For Akoya pearls to be certified as Hanadama pearls, shape of the pearl needs to be perfect round and surface exhibits minimal to no visible blemishes. (*Note : There are no perfectly flawless pearls in the world. As pearls are natural be it cultured or wild, do take note when sellers described their pearls to be flawless) Nacre thickness needs to be at least 0.4mm, have a very strong luster and pearls exhibits mirror reflection. Certification for Hanadama pearls can only be done for a strand of pearls, so be wary if someone tries to sell you their loose pearls as Hanadama.
Now that we’ve gotten a brief understanding on what Hanadama pearls are, lets get back to our main star, the TEN-NYO（天女）．The word TEN-NYO can be directly translated as “A lady from heaven”. The TEN-NYO is essentially a Hanadama but they are at the top of the grading scale. For a strand of pearls to be considered TEN-NYO, it must firstly be certified as Hanadama. Next comes the testing of the ‘Teri’ of the pearls to determine whether the strand of Hanadama pearls are worthy to be called TEN-NYO. Teri is the word for the light interference which occurs on the surface of the nacre. Testing of this Teri can only be done with a special device called the ‘Aurora Viewer’ and it is used to measure the intensity of iridescent colors of the pearls. Only when it gets scored more than 90% then can it be certified as true TEN-NYO pearls.
