Listing a darling pin and matching screwback earrings are marked as 1/20th 12K GF and look like, but are not, Black Hills Gold jewelry. The pin and earrings almost look like a snowflake shape with yellow gold grape clusters as half of the points, rose- and green gold leaves making the alternating points and a central green gold flower. The earrings have a rose gold central flower and gold grape clusters and green gold leaves. The pin measures 1 1/8" in diameter and the earrings measure 1/2" in diameter and 1/2" deep including the screwback which has the gold filled marks on it. To my understanding this is not official Black Hills Gold, but created to look like it with the leaf, grapes, flower elements however the 12K GF makes it not "real", but a sort of simulated version as "real" Black Hills Gold must be higher carat and not gold filled. On the bright side, this set has very nice textural detail on its elements and has been priced accordingly. It is in very good, used condition with no damage of any kind. There are no maker's marks.
