I think it is so interesting that the color of gold can be altered by the addition of different metals in the alloys. Adding a little more silver can make the gold appear to have a tint of green and copper gives a pinkish cast.
These 18k gold earrings are just slightly greenish gold which adds a lovely contrast to the warm tones of the cultured pearls. I have not identified the designer MB but estimate these to be modern earrings.
They measure 15.5mm in diameter and the cultured pearls are 7mm in size. The total weight of the earrings is 14.58 grams or 9.38 pennyweights. They are very finely made with secure omega pierced backs.
They are the perfect earrings for day or evening wear.
