As Caitlin mentioned I do have quite a few natural pearls suitable or in a ring. I could send you photos of all my larger pearls which would be suitable for your ring or post them here on the forum. I have included my email address if you want to contact me. I do have both white and cream naturals suitable. I have been busy and had the flu so didn't see your post before now. Good luck and welcome.
