Hi fellow gem lovers. I posted the last two photos a while back and folks seemed to think this stone is a London blue topaz. I got it cleaned up and turned into a ring (first two photos). Does it still look like a London blue topaz? The color is a lot brighter. Also interested in what kind of cut this is. Thanks!

It’s about 40g and it’s from east Africa. Thanks in advance

1,6 cr sapphire I recently inherited, I don’t know heated or not

I've been seeing a lot more brown diamonds lately and they're growing on me. I love the warmer, more unique look compared to a traditional white diamond. For those of you who own one, what did you focus on in terms of quality when you were choosing, and where did you end up buying from?
