These pearls are from the Tridacna species of mollusk which are non-nacreous pearls. There was a time when these types of pearls were not even called pearls, but that has changed now. Non-nacreous pearls are very much pearls just like their nacreous cousins.

Hubert Bari says this about non-nacreous pearls in his new Pearls Catalog: "Here it is necessary to demolish an idea that is frequently encountered on websites and in books: the claim that only nacreous pearls should be called "pearls", while the others should be regarded as no more than 'concretions'. All the concretions produced by molluscs with shells are pearls, whether they are nacreous or not. They all have the same composition and are formed in the same way. Only the external appearance and the manner in which they react to light are different, which is not enough to justify differentiating one kind from the other in the nomenclature. In fact, the Gemological Institute of America has recently placed a ban on the differentiation between (nacreous)pearls and (non-nacreous) concretions. When you see the splendor of a Melo pearl, it is obvious that this distinction promoted by the lobbies of dealers in nacreous pearls is wholly unwarranted."

Some tridacna pearls exhibit flame patterns that sparkle in the sun or any available light. They also often have extraordinary symmetry making them exceptional choices for rings and matching jewelry ensembles.

Some of the species of Tridacna are Tridacna maxima, T. squamosa, T. crocea, T. gigas, & T. derasa.
