OMG! You've got a Melo pearl! And ... it does have a lab report stating as much already (OK, almost: 'Natural, Non-nacreous pearl').

Now... just ignore the previous post. I was thinking of nacreous pearls - the typical Pinctada Maxima produce. This, is a whole different thing.

There are a few threads around here about Melo pearls, but not much about their commercial value.

Frankly, their valuation is total mystery for me. There seem to be very few being bought and sold overall... which means you may need patience. However, I do remember a couple of fairly high prices for pieces small enough to be worn in jewelry and particularly colorful: from a couple thousand for a ring piece to mid five-figures for a necklace combining Melo and Conch pearls (Sotheby's, Hong Kong).
