JTV 1.75 ctw round Strontium Titanate sterling silver ring- size 5

This is a lab created gemstone ring, it's set with a white, round, one and three quarter carat Strontium Titanate. The setting is 925 sterling silver with an anti-tarnish rhodium finish, the ring is a size 5 and can't be re-sized. This comes with its blue JTV ring box. This is pre-owned and was worn twice, still looks the exact same. If you're wondering what is so great about these gems, Strontium Titanate stones are insanely sparkly. They sparkle and shine more than CZ, Diamond, or Moissanite. -"The dispersion of Strontium Titanate is four times higher than diamond and is responsible for vibrant rainbow-like flashes of color." The last pic with the lone loose gem gives an idea of just how showy these are. They are a softer stone so care should be taken when wearing and cleaning.
