Well respected Taxco Mexico Silversmith Miguel Melendez, created Vintage Sterling Silver Earring (screw back) with stunning, large faceted prong set Blue Topaz gemstone (although I am not a gemologist so it could be the more expensive Aquamarine but I doubt it). Shaped like a flower or 4 leaf clover . When the light hits the curves in the silver and the stunning BLUE stones these really pop.
Marks: M inside a C where the C curls over the M. TAXCO. MADE IN MEXICO. STERLING. Eagle 3.
Measurements: 26.55mm | 1.0” wide and tall, the stones are 9.15mm | .36” round.
Weight: 12.32 Grams.
Condition: Excellent condition. Normal surface scuff, a bit of tarnish on the maker's mark and the top of the screws can all be polished if desigered.
