Question: Can you use this to clean jewelry? Gold, platinum, silver, and diamonds?
Document: I used it to clean my wife's diamond ring and it looks great. I purchased this item for the use of cleaning my wife's and my jewelry.
I use this product primarily to clean my wifes wedding band/engagement ring. When you take a ring in for routine maintenance/cleaning, jewelers typically use steam to get all the gunk and grime off. I have to refine my technique, but so far so good! I also bought a snap mesh tea ball strainer to hold the jewelry in place while I steam it. Also works great for streaming clothes. I don't anticipate using it for cleaning the house, but it's good to know I have the option.
This is a complete waste of money. Do not order this brand or this model. It worked great for a couple weeks, we use it for cleaning jewelry and other small items by just spraying them. After re-filling the water a few times it just stopped heating up. The light goes on, goes off, but it won't produce steam and the base isn't warming at all. Go with a more expensive one or a bigger one.
Based on the good reviews, maybe my expectations were too high. I have a larger steam cleaner that works well, but I wanted a small one for quick touch-ups. The included attachments were nice, but the unit was a bit larger in my small hands than I expected from the pictures. After reading the instructions, I used it once, but it failed to clean my test area:  the gold-colored light fixtures above a bathroom mirror.
My wife loves this steamer... The water capacity is kind of small so refills are more frequent. I think they engineered it that way to minimize warm up time. The super heated steam cleans everything from tile, grout, soap scum, jewelry, etc. We have little ones so not using chemicals is a plus, just steam! Be careful when threading on the cap make sure the threads are engaged properly.
We live in a small condo apartment and I was able to use this to clean the deck and the windows. Easy to use and compact.
This thing is cheap, so don't expect something amazing. Useful to have on hand to clean caked on grime, but it's a kind of a pain to use.
Steams good, but doesn't clean as I had hoped. Good for santitizing but you're still going to have to use some elbow grease on the worst areas.
I bought it to clean my windows. I use it on everything. it works great and it is small. My bathroom is sparkling clean and no chemicals.
This is a great small steamer cleaner. I bought to use to clean parrot cages, ended up cleaning bathrooms and my kitchen. I love it!
Answer: noooooo, the pressure is too great.  sonic cleaner is best for most gemstones.  or  u can use ammonia water on them with a soft bristle brush.  do not use ammonia on coral, jade those types of gemstones it will damage them.
