help finding a pair of sapphires for studs

[himni]

I am looking for a pair of sapphires, to hold. And next year I hope to set them. But i am so lost. The price variation is so difficult to understand. I know that I want a pair from Ceylon or Madagascar. My max budget is 3k, but i hope to stay under that as much as possible. My wishful size would be 6mm in length, I want round or cushion



Is a heated sapphire looked down upon in the gem world? does it make much less valuable?



here are some of my choices so far,

what i want them to look like:

I am obsessed with these earrings, I was even thinking to contact LM but I hate asking vendors for quotes when i am not gonna buy from them and I don’t think he would just sell me the sapphires now.
