Vintage 18k & platinum two tone natural diamond cluster ring size 6.25

Such a sparkly and dainty ring! Perfect promise ring, anniversary gift or for Valentine’s Day! Marked 18ct and Plat inside the band. This is a mid century vintage ring from England. Not sure of total diamond carat weight, but I’d say at least .25 -.30 carat total weight. Some very slight nibbles to main stone. Weighs approx 3 grams. Ring size 6.25. Does not include antique ring box.
