The ruby inserts are a fairly new product and VERY pricy! They apparently are better at retaining heat and do not chazz like quartz often does over time. But quartz only chazzes if you overheat it with containments. This we feel is a gimmick and one would be better off getting a Silver Surfer with the quartz dab dish.
