Simple -- and stunning in its simplicity!
Black pearl is such a unique material for jewelry! These are almost identical (but slight differences make them barely distinguishable from each other), and both measured 5.5/16ths of an inch, which is exactly 9 mm as stated in the web presentation. As you can see in the picture, they do have a dull shine or luster. They will make a great statement when my wife wears them. You can't get any subtler of a statement than a black pearl! Simple but elegant, and stunning in that it needs no other statement (like gold or silver or other jewels) to stand out. Absolutely a 5-star product!
