Vintage 9ct Yellow Gold Diamond and Ruby Cluster Bangle

One oval ruby approx 5mm x 3mm, surrounded by 12 diamonds. Total weight, 7.2 grams. Diamonds are sparkly, ruby is facet to reflect light. Very good red colour Hinged bangle with box clasp fitting. 2 safety clips Opens by pressing small bar, see last pic. Bracelet is fragile and small. Open carefully. My wrist is 6.25 inches for comparison. Makers mark on part of closure that inserts, to small for me to make out, even with a loupe. Vintage, lovely piece. Was told it was a wedding present for a bride, she must have been quite petite. Bought by me at UK auction. Low ball offers will be ignored.
