Yes, opal is relatively fragile, but not as fragile as many people believe. They are rated 6 on Mohr's hardness scale, and have the same strength as the equivalent piece of glass. they are quite stable, and difficult to crack, but naturally should not be allowed to slam into hard surfaces. They do not crack, and it is a myth that they need to be rubbed with oil to prevent cracking (they are non-porous and do not absorb oil or other liquids).

∙ 9y agoUsually precious opal is more expensive than a pearl of the same weight. But this all depends on quality. A high quality precious opal with high fire is usually much more expensive than most pearls. Most pearls being the common cultured freshwater or salt water pearls. However, rare pearls like natural saltwater pearls and conch pearls are very expensive and can be worth more than decent quality opal of the same weight.
