NOTE: Most all of these rings run in whole sizes - I do carry sizes 4 1/2 - 15 ... supply varies by ring. Sometimes they are made a bit larger or smaller....so when possible I can accommodate half sizes - otherwise go up to the next Full Size to insure a perfect fit. A ring guard can be added to make the ring smaller - unfortunately, these rings can not be re-sized by a jeweler. All rings are made with genuine Lab Created Stones & Brilliant Cut CZ's (unless otherwise stated if Genuine Stones) - which are of the highest quality cut with the greatest amount of brilliance & reflective play on light - the closest thing to real QUALITY gemstones - almost an exact match to nearly flawless diamonds & real gemstones in terms of color, cut, clarity and carat! CZ's come in five grades ..... "AAAAA" is the highest grade and the most expensive ... we only buy the very best stones!
