A Large Pear Shaped Blue Topaz Diamond Halo Ring in 10K Yellow and White Gold

Vintage 1990 10K yellow and white gold ring featuring a large 15 x 10 mm blue topaz, approx. 7 cts, set by prongs. Surrounding the topaz are round cut diamonds set in white gold prongs. Please note this is a preowned ring and closeup there is evidence of wear on the facet junctions and light wear to the table. Not damaged-no deep scratches or chips but normal wear. I've priced this accordingly. Still it is a large nice colored topaz and would be a shame to scrape it. Currently a size 6.5 but message me if you need a sizing estimate. 5.3 grams
