I also sorted them out into colour because I feel like since pearls are meant to be servants/accessories they should at least fit the colours of their diamond (not saying every gem has to fit the colour of their diamond)
White Diamond = 8
Yellow Diamond = 19
Blue Diamond = 20
Matte light sapphire
Matte light purple
Matte light plum
Pink Diamond = 13
All together there are 60 types of pearls!
That’s a lot of pearl
If you know any more types tell me and I will update the list
I finished all of the fan gems that will eventually all be in a comic together, the group of gems found on an earth like planet known as the Organic Gems (in order, Coral, Amber, Petrified Wood, Ammolite, Ivory), and the Homeworld gems sent to clean up said planet known as the infamous White Diamond Special Tactics Unit (in order, Onyx, Topaz, Agate, Sunstone, Jade). They’re all fighting over a very unique gem, Carbon, who can, with enough time, become an entirely new Diamond. Its up to the Organic Gems to make sure Carbon can develop before the WDSTU can break them.
