I have obtained a small parcel of gorgeous black Tahitian pearls. This pearls are authentic blacks, and have not been dyed nor colour treated in any way. This parcel of pearls is a deep, minky silver-grey, with subtle green undertones. They are all around the 8-9mm mark.
I set this one in a bezel of 14k gold. I used my graver to create a glittery linear texture on the metal. The band is hammered 18k yellow gold, and is a size 8. The band is 4mm across.
