Caring for Opal

on . Posted in About Opal

Treat Opal with care as you would any precious gem or investment; avoid heavy blows, abrasives, harsh chemicals and extreme heat.

Although you probably would not wear any gemstone jewellery while gardening or washing the dishes, solid Opal jewellery is actually best cleaned using a soft cloth and mild kitchen detergent in cool water.

Good Morning,
I have just found your wonderful website.
I produce a monthly e-newsletter which is circulated to the Tourism businesses in Coober Pedy and neighbouring stations plus the Info Centres around SA & the NT.
I wondered if I could use some of your Opal info in my October Edition (Opal Month), mainly the parts in your “About Opal” section – names, spiritual info etc.
I would obviously reference it to your website noting the address so others could read your site.

I am wanting to use your site in an assignment as it is a superb example
of a site to use for a primary teaching unit on gemstones.
Many thanks,
