This is a Diamond engagement ring (kinda obvious)
And this is an Opal engagement ring.
Just my opinion but why isn’t opal a giant thing :? You also get crazy variations like the Lightning Ridge Black Opal….
Dragons Breath Fire Opal…..
Even this fucking Harlequin Opal that looks like a rainbow on LSD
…JUST… OPALS MAN
The reason opals are not good engagement ring stones is because they are suuuuper soft and get scratched easily, meaning they have to be replaced often. Diamonds (and most other gemstones) are hard enough to withstand the daily wear an engagement ring gets.
However, the reasons diamonds are associated with engagements is due SOLELY to a marketing campaign by DeBeers.
