This works great, but be careful with gem stones. Some of them like amethyst and emerald and any others which are in the quartz family are heat sensitive. Just put them in once the water has cooled down some. Cubic Zirconia are fazed by anything. They are lab grown under high heat and pressure. I fire them in a kiln at 1650 degrees in silver metal clay jewelry, and they are bothered at all.
I tried this and it worked great for some of my pieces (all are 925 silver from Tiffany) but one of my necklaces actually turned darker. Tried the solution two more times and left it to soak, tried to use a polishing cloth after the solution under running water and no change. So bizarre because it worked like magic on all my other silver. Thoughts?
I just went on your site this morning because I had a lot of jewellery to cleaned. I found that all glitter like gold. The other things are glittering as well. I always used the commercial brand but it ruined quite a few things.I Used all the things that were called for and it worked out fine. If you have a high piece I just put it in a smaller container.
