Sterling Silver 925 Opalescent Mexican Ring Size ~4.5

Size: ~ 4.5 925 Sterling Silver Made in Mexico This beautiful, unique sterling silver ring is squared off at the top, and features 2 opalescent bars (unsure if it is actual opal, but I believe it is) across the flat top of the ring. The under side is stamped "Mexico" and "925" The size is very small between 4 and 5! There are no flaws or damage, but this is a vintage item.
