http://www.aussietreasurechest.com.au/shopcontent.asp?contentid=26 Storing Opals:
Storing your opal for a period of time is quite simple. It is recommended that you wrap your opal in some cotton wool and place it in a sealed plastic bag with a few drops of water. This will give the opal a controlled environment and will prevent cracking. It is safe to keep your opal in a safety deposit box or bank vault for long periods by storing the opal in this manner. This is how we store our more expencive opals in our banks safe.
Opals and water:
Water does not harm solid opals. There are different opinions associated with solid opals. Some say it is good for the opal to be immersed it in water overnight to maintain water content. Whether you place the opal overnight in water or not, it will not harm�the opal.

http://www.jewelsforme.com/opal-science If opals get too dry, they tend to crack. This phenomenon is called “Crazing,” and it wipes out the value of the stone. You should avoid leaving your opal near anything potentially drying. To keep your opal from drying, it may be helpful to immerse it in water for several hours from time to time.
LZ 这是我第一次网上与人辩论，只为尽力科普澳洲欧泊。我不支持你关于长期保存澳欧泊的观点。我的观点是长期不带的澳欧泊不需要泡在水中，只需放于黑暗，不过于干燥，不靠近热源的地方。如果欧泊必须要被放在过于干燥的地方，象国外的保险柜或保险箱，那里面绝大多数含除湿恒温功能,需将宝石同一块湿棉布一起放入一密封塑胶袋内保存，因为欧泊必竟是有一定的含水量的宝石。我相信这也是澳洲本地珠宝商对于保存澳欧泊的方法。
对于LZ 所提供的两个网站，第一个网址是澳洲本地昆士兰的珠宝商专营澳欧泊．第一段话店家也建议将贵重的欧泊包于湿棉布并密封在塑胶袋内再保存于银行保险箱里，这里隐含了一个常识，澳洲本地银行保险柜都有除湿装置,里面相对外界很干燥。注意这点，即使在特别干燥的环境中店家也未主张将宝石泡水保存。
第二段话欧泊和水的关系，店家观点很客观，水不会伤害欧泊。 至于外界一些将宝石泡水保湿的说法，商家只支持宝石泡或不泡水都不会被损坏。
LZ 所提供的第二个网址是美国纽约的一家珠宝公司,这家公家销售世界各地数种彩色宝石。LZ 那段话有些断章取义,整段全文如下
Your opal will last a long time if you take good care of it. You should treat your opal with some care to prevent any scratches or blows. The stones should never be kept in oil or any other chemicals. This may cause them to lose some or all of their fire. Because opals contain some water (as much as 20% water), they should never be stored in a bank or vault for long periods of time because of the dehumidifiers used in many vaults. If opals get too dry, they tend to crack. This phenomenon is called “Crazing,” and it wipes out the value of the stone. You should avoid leaving your opal near anything potentially drying. To keep your opal from drying, it may be helpful to immerse it in water for several hours from time to time.
这个商家建议不要把欧泊放入油内或任何化学溶液内。并且宝石不应长期放于银行或金库保险柜内因为那里通常有除湿功能。如果欧泊长期处于干燥环境中，会因失水而破裂。这种宝石龟裂现象会造成宝石巨额贬值。这家店主认为把欧泊分次放入水中几个小时有可能助于宝石保湿。不过要注意，这家美国珠宝商是兼营欧泊,而且他家的欧泊并未指出全产于澳大利亚，个人认为这是兼营与专营的区别。
个人觉得每种宝石只要存在都有各自价值与特色。
对于各种竞争型宝石希望各个卖家在充分了解的基础上再发表意见，毕竟市场的发展结果是万花齐放。
