I’ve been using Jewel Brite liquid dip and the polishing cream for MANY years. I used to buy it at the Gem & Jewelry Shows in Los Angeles and Pasadena, Ca. During and after Covid it became difficult for me to attend the shows & I lost track of the product. I tried others from Amazon with inferior results. I finally found the JB website!! Hurray!! JB products simply have NO competition in my opinion. I use both liquid and polish crème on ALL of my jewelry with excellent results. I have many pieces of fine quality gold & silver as well as copper, brass, and base metals. Many are one of a kind artist creations. Many are embellished with natural opals, diamonds, pearls, emeralds, rubies, tourmaline, turquoise, topaz and even lab created stones of many types. Jewel Brite cleans, polishes, shines and protects ALL of my pieces. I have always cleaned it by hand, but I’m going to also purchase a machine to use with the liquid. I’m a total JB fan. I hope your business continues to prosper!!
