Excellent!! that is the right word to describe Connoisseurs Jewellery Gel & Brush! This product really works and the shiny clean results last a long time too! This is my second purchase after 2+ years with first bottle that I used at least weekly to clean general muck, oil & acrylic paints, soap buildup, gardening dirt, and glues/adhesives used in jewelry making from my multiple rings that I wear regularly. As a landscape artist, professional jewelry making AND an avid, hands-in-the-dirt gardener, my jewelry gets VERY DIRTY all the time!  However, since discovering this product, unless I absolutely have to, I don't take my rings off when doing work with my hands. As a result, they get all kinds of stuff all over them but I know I can depend on this stuff because it really works!!

For several months, I had tried multiple products designed to clean jewelry (and some unorthodox methods as well) to get some severe, oil-based, dark mahogany wood stain and a few layers of high gloss lacquer top coat  off of my favorite jewelry that was accidentally damaged (from many hours doing all of the staining & finish work on the natural woodwork throughout our newly built house) I was horrified after discovering that my "protective gloves" had allowed some of the petroleum-based products to seep through the latex and had horribly stained all of my jewelry as well as my hands!

I thought there was no hope of cleaning them after using all kinds of other products to remove the stain & lacquer with little or no success.  In fact, the most badly damaged one, my "mother's ring", was stained so badly that all of the birthstone colors (light aquamarine, deep sapphire, light emerald, & light amethyst) were all stained a glossy, deep mahogany brown that wouldn't come off no matter what I tried, including mineral spirits & turpentine & other products designed to strip paint! Those products got it off of my skin and did take off the layers of lacquer on the jewelry, but the dark stain color just wouldn't come out of the stones & was moderately discoloring the metal everywhere that was not perfectly smooth and horrible inside the settings where I couldn't reach to scrub them.

It seemed hopeless and I thought that I'd have to replace all of the stones until having a random-chance encounter with this product. A casual acquaintance that I'd met at a house-party happened to mention using it to clean her precious jewelry after something similar to what happened to mine, happened to hers. I lived nearby so I went to get my damaged jewelry to show her thinking that hers couldn't possibly have been as bad as them. She said they were! Generously, she offered to let me try hers to see if it would work on mine before I bought some of my own. She said that if the discoloration was improved at all, that it would probably work for me, so I tried it there. It was amazing! In fact, all of the gold & sterling settings all cleaned up immediately! Ditto on the diamonds.

The next day, I got some of my own. It took three more back to back scrubbing/cleanings to finally get the dark brown stain completely out of the stones in the "mother's" ring! I was encouraged because with each subsequent cleaning, I noticed all of the stones getting lighter and lighter, slowly returning back to their original colors by removing the stain that I'd mistakenly thought had fully penetrated them. The jeweler later told me that THAT would be impossible so we figured out that the dark stain had most likely just penetrated the stones very slightly, but had actually built up on top of a layer of lacquer covering that first light sain so the lacquer layer had apparently protected the stones from the subsequent stain layers AND had prevented the stain itself from fully drying when exposed to air. Thus, I was dealing with a stain that was mostly sitting on top of the stone's protective polish, which had been severely stained but not penetrated into the porous air pockets of the stone itself (AMAZINGLY LUCKY!) Even more hopeful after that success, I tried it on an already given-up-for lost opal ring that was damaged at the same time. Even most of that stain slowly but surely came out of the stone over 3 scrubbings! Within a month, that opal and all of my other rings were back to "new".

The rest of my more normal types of "dirty jewelry" (mud, artist's paints, glue, soap, etc) all cleaned up beautifully with the very first use. That and the fact that my horribly damaged jewelry was restored pretty much proves that this IS an amazing product that not only keeps all kinds of jewelry looking like new but that it can restore some seriously damaged jewelry back to "new"! I am still amazed that this product actually worked so well and very grateful indeed! Now, I use it weekly to clean up my jewelry and always count on it to keep it looking like new no matter what I expose them to. I don't even bother to use my ultrasonic cleaner anymore because I really don't need it if I use this and it couldn't be easier! Because of that, I recommend it to all of my jewelry customers to keep the items they buy from me looking like new.

One important note here: I wouldn't recommend carelessly wearing your jewelry when using oil-based stains OR even with special gloves because, if not for the polish on the birthstones and the light layer of lacquer that was on top of the original light coat of stain, there is no doubt that the subsequent stain WOULD have fully penetrated the stones and made it impossible for anything to clean them up!  It wouldn't matter how good a product is, there are things that cannot be fixed... However,if someone accidentally got something nasty on their jewelry, THIS product would be my first recommendation to try to salvage it!

Finally, for the record, I want to reassure readers by saying that "NO, I am not affiliated with nor being rewarded by the manufacturer or any other representative of this product for writing this review or for so enthusiastically recommending it to other people." I just LOVE this product for how well it worked to restore my jewelry and the wonderful job it does in keeping them looking like new even though I wear them 24/7. It is the best jewelry cleaning that I've ever used!
