Tanzanite followed close by blue sapphire then third emerald tied with aquamarine.
Gold stone... it's sparkly and warm :D
I love the opal. And the onyx is a close second.
They are only bad luck if you wear them and your birthday is not in October... (I love stones & pearls cuz I am a June baby - we get 3 birthstones) :D
Lucky for me, I don't believe in all that bad luck stuff. And even luckier that I never wear jewelry.
lol... I don't like putting limits on myself but I don't want to tempt the fates either....
Jade and onyx equally.
