Green tanzanite and black spinel set in solid 925 sterling silver. The platinum plating for added protection and shine keeps it from quickly tarnishing when not worn. When you wear a piece of 925 Sterling silver jewelry daily, it will not tarnish, but when you put it away without an anti-tarnish strip or other anti-tarnishing aids, it will normally tarnish rapidly. You can revive it with silver cleaner or polish, but when it is plated in platinum, you will rarely have to worry about tarnish at all, unless you store it for years without anti-tarnishing aids of any kind.
1.26 cttw (combined tanzanite and spinel)
Comfort fit with smooth underside to the setting so that there are not thin, sharp edges digging into your skin when you wear it. (See pics).
This ring would make a great spirit vessel, portal, or as a reward or a gift to yourself for being the awesome human being you are! Looks great on aliens, as well. (Just wanted to see if you were paying attention)!
