Diogelorcas Pearl
by Muhammad Daloma
Diogelorcas Pearl (Blister Pearl)
It was formed by a giant mollusk commonly called "taklobo" with a scientific name "Tridacna gigas". The size of the blister pearl is 4.00 inches in diameter and 3.75 inches in height. The mother shell where the blister pearl is naturally attached is 33 inches in length, 18 inches in width and 8 inches in thickness. The color of the blister pearl is crystallike white-ivory. The blister pearl itself is slightly fossilized with skin-deep corrosion. But its luster and brilliance can be scientifically restored because it is hard, sturdy and solid. The mother shell’s concave part is likewise slightly fossilized. However, fossilization near the brim and at the convex portion of the mother shell is at the advance stage already.
