I like the pun...if that was your intention. Opal rough (rock before it's cut) tends to be on the softer side than the other precious gemstones (ruby, sapphire, emerald). It has a hardness between 5.5-6.5 on the mohs scale. So opals when constantly worn could become scratched and needs to be repolished time to time
A sponge can be both soft when wet and rough when dry.
Opal has a hardness of around 5.5 to 6.5 on the Mohs hardness scale, which means it is relatively soft compared to other gemstones. This makes opal prone to scratching and requires gentle handling and care.
Yes, opal is a relatively soft gemstone, which makes it prone to scratching and chipping if not handled carefully. Additionally, opals have a relatively high water content, which can lead to cracking or crazing if exposed to sudden changes in temperature. It is important to take proper care of opal jewelry to prevent damage.
The types of Opal that i am familiar with are White Opal, Fire Opal, Boulder Opal, Black Opal, Crystal Opal, Light Opal, Doublet Opal, Triplet Opal, Common Opal, Synthetic Opal, and Immitation Opal.
Another name for opal is "fire opal."
