Statement 9ct Gold Cat's Eye Sillimanite Dress RingA stylishly confident 9ct yellow Gold and inky purplish brown hued oval cabochon Cat's Eye Sillimanite dress ring (a gemstone mined at several places and first discovered in 1824). A contemporary design with a classic Modernist vintage styling which is a fab statement upon the hand, it is fully hallmarked for 2005 at Birmingham. The ring size is an 'N' or '6. 5' but could easily be altered to suit.
