Sterling Silver Marcasite and Turquoise Turtle Statement Ring

This is the CUTEST ring! It has a very large round turquoise colored stone. I am not sure if the stone is actually turquoise or not so no guarantees. The ring is a size 6.75. The turtle is covered in small marcasite stones. The turquoise stone measures approximately 1.10" across ans sits up approximately 0.5" on the top of your finger. It is in very good used condition with some light scratches and dings from normal wear. The turquoise stone does spin around a little bit but it seems to be completely secure-just a loose fit. I do not see any missing marcasites. The only marking on the ring is the 925 for silver content. The toal weight of the ring is 15g. (Bin#MU1)
