ISO PAUA Abalone Shell Jewelry to complete set

I have a very nice probably a Paua shell necklace (thanks, Old!) and watch and would like to have at least a pair of earrings to match. Might be interested in a ring and bracelet too. I do make jewelry so just the abalone pieces might work if the holes are pre-drilled. Shape must be round and color of shell should somewhat match but design can be different. I've looked on the site and just can't find anything - it's either too pale (abalone) in color, not round or not set in goldtone metal. I've been to craft supply shops in the area and haven't found anything. Help, please :D
