Victorian 15ct Cabouchon Garnet Pendant

Victorian oval yellow gold pendant measuring 29mm x 24mm (not including the top ring) set with a cabouchon garnet measuring 17mm x 12mm.  No hallmark but testing as 15ct gold.  The pendant has a light swirly engraved pattern around the garnet.  Unfortunately we do not have the original chain but have paired up the pendant with a modern 16" 9ct gold fine trace chain.  Gross weight 6.5g.
