Cracks in Opal????
#Opals are more fragile than most gemstones, however they’re not as #fragile as some people imagine. Opals are about the same hardness as glass, so imagine you’re wearing a piece of glass and you’ll get the idea. Avoid heavy manual labour, moving furniture, #sport, #gardening or any other vigorous activity where your opal might impact with hard surfaces !
Already cracked Opals can be soaked in #water or rubbed with oil to hide the flaw temporarily !
#Causes of crack – Strong light or extreme heat can make opal expand and dry out,
Which can lead to cracks!
