This is a gorgeous statement piece! Large round light green jade cabochon bezel set in 14k gold. The ring shank shows at size 8.25 on my ring mandrel.  I normally wear around a 7.25 and I'm able to wear this ring comfortably because of the wide shank so this ring should fit in that size range.  A jeweler can size this ring band easily if needed. 

Hallmarked "KEVIN" 14K and 585

Weight approximately 13 grams (on my scale)

This is a vintage piece with minor scratches commensurate with normal use and age.
