These are popular flat coin shaped pearls at 12-13mm in sizes.
There are 2 colors available: black and white. The black pearls have multi-color from copper, green to blue overtone as the picture shown. The white color comes with pinkish white and pure white.
Two graded pearls are available for both colors. AA- graded pearls have a few more surface markings and flaws to show they are made of nature. The only one is AA+ grade with more uniform shapes and few markings and flaws, as you can see from the pictures. Both grades come with very nice high luster. Even with the lower graded coin pearls with flaws, they still look nice on the other side so depending on your design of the jewelry, it may still suit your needs effortlessly.
There are approximately 31 pearls on a strand at 15-15.5in long.
The picture is taken from real strands with a penny next to it to give you a sense of the size. The last picture shows the difference of AA+ grade on the top and AA- grade at the bottom.
Sorry AA+ graded have been sold out. Only AA- graded black pearls are left.
