Black Hills Gold Double Leaf Stud Jackets

this is a very nice piece of Black Hills gold ,the leaves look to be pink and green gold,and the stems yellow,these are very tiny ,the black tile they are on is 1 inch across, one is marked 10K the otherlooks like JRL but i really can not tell for sure, the ball studs and backs are not original to the leaf jackets, BALL STUDS AND BACKS ARE NOT GOLD,But it is what i had, the total weight of the leaf jackets alone is about a half gram ,measuring from one leaf point to the other ,they measure a quarter inch across ,the ball is about 1/16 of an inch across,i dont think anything much larger would work as it would cover the leaves and stems
