Rubies are beautiful and expensive gemstones. According to, the most important aspect in determining value is the color of the ruby: “The term ‘pigeon blood’ color has been used in the gemstone trade to characterize a perfect, fiery luminescent red of a perfect ruby.” To keep your rubies looking great, or to improve the shine on rough, old or dirty rubies, make sure that you use the right kind of gem cleaner on them. This will help the gem keep its luster and value.

Things You'll Need

Pour some gem cleaner into a large bowl. It’s best to clean your ruby (and other gems) in a bowl rather than over the sink to prevent the gems falling down the drain.

Place the ruby (or rubies) into the bowl of soapy cleaning solution. You can use a gem cleaner like Blitz Gem and Jewelry Cleaner. If you do not have a gem cleaner, you can use liquid anti-bacterial hand soap, which works great to clean and polish rubies.

Clean the ruby entirely using a toothbrush. Brush the ruby gently.

Pour cool water into a separate bowl. Place the ruby or rubies in the separate bowl to rinse them off. Make sure that all of the soap comes off of the rubies.

Pat the rubies dry using a soft cloth. Place the rubies in a jewelry bag for storing.


  • Although rubies are a tough gem, be careful in choosing the cleaner. Some chemicals can strip away a ruby’s luster. Also, do not leave rubies in any gem cleaner. This can also reduce their shine.
