9ct White Gold 1.78ct Elongated Oval Blue Topaz Dress RingMade in a bright white 9ct white gold that compliments the blue topaz beautifully, this dress ring features an 1. 78ct elongated oval blue topaz gemstone which elongates the wearers fingers and hands and gives an overall elegant look to the piece. With four double claws in each corner, the blue topaz is held securely in place. To add a little flair to the design, the gemstone sits on a twisted style band which goes around three quarters of the band.
