Authentic Honey Amber Jewelry Set Earrings Pendant Brooch Vintage Signed

Botanical Leaf shaped clip on earrings are paired with matching brooch in a grapevine motif. Signed with the "hallmark" of Kaliningrad (whose specialty is Amber.) The earrings measure 1-1/4 x 3/4" east to west with beautiful amber in a goldtone setting with paddle backs. The tension clips are in good order and work as they should. The brooch pin is a delightful (rendition) of a grape cluster where in delightful fashion the grapes actually swing and move! Measurement of the pin is 2 x 7/8" with a pinback that attaches via a hook (as opposed to rollover) and bears a wire loop to wear as a pendant. The setting is the same goldtone as the earrings. This particular piece is unique to others that are out there 9 individual grapes in contrast with others that have 7. My estimation is that this piece is more vintage than most. What year, I don't have enough information to say. Another possibility is that the pieces are actually gold-filled. More info to come as I have it tested. The Set is in nice vintage condition with patina consistent of pre-owned pieces of their nature and time. These pieces are highly collectible and would be appreciated by any curator of unique and rare jewelry.
