Hanadama Japanese Akoya Pearls Necklace
“Hanadama” refers to the finest and highest quality Akoya cultured pearls in the world. It is also translated in Japanese as “Spherical Flower” and are also often called “Flower Pearls” in the trade. They have an extremely high luster due to their superiorly thick nacre, often the highest that an oyster can produce and near flawless surface.
There are no standard international grading however these attributes are analyzed and certified to meet specific levels set by the Pearl Science Laboratory, Japan. They are the most trusted and strictest laboratory with set of standards published. Each Hanadama strand accompany with an authentication card or certificate with an authentic number from the Pearl Science Laboratory.
In terms of the production they are also very rare and supply is very limited, as only 1 in every 500 AAA Akoya pearls qualifies as a Hanadama. Only a few Hanadama pearls are produced each harvest, making it far most valuable than any of AAA Akoya pearls.
Pearls come from a living sea creature. Most pearls come from oysters either freshwater or saltwater environments.
As oysters grow, an internal organ called the mantle uses minerals from the oyster's food to produce a substance called nacre. Nacre is the material that forms the oyster's shell. When a foreign substance, such as a grain of sand, may find its way into the oyster and get stuck between the mantle and the shell.
To protect itself, an oyster's natural reaction will be to cover up the irritant layer by layer of nacre. This substance, usually used to create the shell, will instead form a pearl.
Graduated Pearl Necklace
All graduated pearl necklaces can vary in size but a very common size starts with a central larger size pearl and graduates to a smaller size so the necklace flows evenly from small to large and back to small again.
Truthfully, creating this type of necklace is labour intensive. It is much easier to match a uniform strand pearls rather than match a pearls progressively smaller along a necklace.
In 1938 there were 360 active cultured pearl farms in Japan producing almost 11 million akoya cultured pearls. However, there were still limited quantities of Japanese akoya cultured pearls so creating uniform strands of pearls was close to impossible. So, the graduated strand of pearls was born. This marked an easy way to create a stylish pearl necklace that was not dependent on a full strand of identically sized pearls.
