Brownish Pinctada Maxima Shells

[jevont]

Has anyone encountered pinctada maxima's pearls with brownish / bronzeish color? Is it common in some areas?

Definitely curious if there's example how the end result might look like and if there were any commercial interest in the past.

These certainly look to be of the "Golden Lipped" variety.
And golden pearls are being produced today! So, they are commercially coveted!
