My jewelry definitely sparkles after I use this. Much better than the brand I had previously. Also, their site gave information on cleaning precious stones and I learned something I did not know about my emerald ring - I now use the pearl polishing cloths on this ring.Love this jewelry cleaner. It does an amazing job even on the dirtiest jewelry.This is really worked product! I've clean my all jewellery. I eaven didn't expect that my so tarnish earrings will be cleaned so easy.I bouught this on amazon deal but if next time I will need it I will buy same cleaner.the liquide changed colour a little bit after use but in two weeks I;ve used this one again (my cousine brought his so tarnished chain) and it's still worked so well!!Recomended in 100%I usually use Goddards, but it wasn't available when I needed to order some more, so I got this because of the generally positive reviews. 1: the directions are only on the box, so you need to keep this. 2: the film covering the top cannot be removed without a knife. 3: the piece of plastic holding the basket doesn't have a clip or similar to hold it by, so it keeps slipping away. 4, the basket is not tall enough, so things like chains can fall down the side. I used it to clean my silver jewellery, but it worked no better than boiling water and washing up liquid. 5: it doesn't say to use gloves, but my hangs are now stinging (had to use them to get the silly basket out which kept slipping back in) so it's not good. Lastly, a part of one necklace still wasn't clean after 4 minutes (double the recommended time), at which point i gave up and threw the whole thing away.I bought it to clean up my diamond earrings every few months (shampoo/conditioner gets them a bit mucky). This seemed to be effective the first few times but when I used it this morning it didn’t seem to shift the deposits. So I bunged then in some boiling water with washing up liquid and could see the difference immediately.I bought this product as I use their Silver Cleaner which is very good also. The Jewel Cleaner did very well at making the diamonds sparkle again and the little brush gets into the settings which were bunged up with sanitizer and hand cream! I finished off the platinum setting with a Town Talk silver cloth and my ring sparkled like new even though it is over 80 years old! It was my late mothers engagement ring.Used this on my 2 very different rings - one silver ring with diamonds and one gold ring with sapphire - and it works a charm! Only had to have them in there for 2 to 3 minutes and used the brush on them also, and now they are like new!The product itself smells and feels a lot like washing up liquid to me, but hey if it does the job We'll, I'm happy! Would recommend.
