The cabrera screw topped ring is designed as an affordable, adjustable option for showing off your ring toppers, and is a great choice for a gift.
Made from 5mm wide by 0.84mm thick sterling silver, with a stainless steel screw, it is available in two sizes - this listing is for the medium/large to fit ring sizes from approximately P - Z (UK) or 7 - 12 (US). However the simple adjustable band will easily accommodate sizes outside these ranges.
The stainless steel screw will fit ring toppers made with the most popular M2.5 size nut.
Ring topper shown is not included, and was from http://www.etsy.com/shop/littlecastledesigns
See my other listings for the large version, and also for the alternative design for children or smaller fingers.
