Vintage Watermelon Glass Pendant Necklace Rhinestone Screw Back Earring Set

Estate 1-Owner, Vintage 70s, pendant feels like glass, according to my research this is called Watermelon glass (can’t guarantee) with a gold tone flower in the center that feels like metal. The clasp of the gold tone chain is stamped Germany. The last picture is how this set has been stored for decades, same card and box. I believe the card the chain and earrings are attached to is original for the necklace, but not certain. The screw back earrings were worn and stored with the necklace, but I do not know if they were purchased together as a set. Set has not been cleaned to avoid potential damage. Desired cleaning is left for new owner. Please see all pictures and video to aid in description and for signs of age and wear. You will receive the set with card and box shown in last picture. Unique and beautiful vintage treasure! (All photos and video taken in natural lighting, no filters used.)
