Alj, thanks so much for posting that! That''s why I wanted to hear some responses, because I thought aquas were somewhat soft (in the Beryl? family like emeralds) and didn''t know if they could take it. I will look thru that link you posted.Date: 1/9/2008 2:33:32 PM

I''ve always understood ultrasonics to be safe for ''red, white and blues''.....diamonds, rubies, and sapphires.
What you posted above is somewhat contrary to what I''ve understood about aquas.

What you posted above is somewhat contrary to what I''ve understood about aquas. Here is more what my understanding is for them....and I found this data correlated here: http://www.18carat.co.uk/aquamarine.html
''Aquamarines do not like excessive heat, and although they can tolerate temperatures above 100c (the boioling point of water), it is advisable to use warm water rather than hot water, to reduce the dangers of thermal shock.
It is not advisable to clean aquamarine in an ultrasonic tank. We sometimes risk it with our own stock, but we would never clean a large or valuable aquamarine which did not belong to us, in an ultrasonic machine. ''
From another site: ''Avoid sudden temperature changes, steaming, and contact with cosmetics, hairspray, perfume or household chemicals.''
Another site: ''AQUAMARINE - Do not use an ultra-sonic machine; avoid heat as it may cause discoloration. ''

Do you know if the ''red'' applies to garnets as well? I''ve heard they''re very durable, but I''d love to know more about it if you know!

Garnets are fine. Not sure where the red white and blue statement came from, but as I have already dissagreed with tanzanite, then I stand in contrast to that statement.
However, most of the home units do not vibrate at a high enough speed to be problamatic to any but the most fragile stone (other than something like opal doublets which are in danger of becomming unglued and of course pearls which will absorb the liquid through their drill holes if drilled, causing them to look wierd...).
Some of the professional models get to nearly boiling in the course of the day since they are often left on all day. That is when you get the thermal shock and awe!

Thanks for all the replies. How about tourmaline?

Tourmaline is found in every color of the rainbow, except blue. If any of this doesn''t sound right, experts, please chime in!
Thanks so much old-fashioned girl! I appreciate the information!Date: 1/11/2008 7:09:59 PM

Here is what the website I cited above says:
AUGUST BIRTHSTONE - PERIDOT
The apple-green color of Peridot is the gemstone designated as the August birthstone. ...Peridot is somewhat durable with a MOH''s hardness of 6.5 -7, but should still be handled with care. use care when cleaning peridot ultrasonically, however we recommend you avoid cleaning it with a steam cleaner since extreme heat may cause fracture in the stone.
If any of this doesn''t sound right, experts, please chime in!
