So I am looking for a Sapphire ring webshop in the UK. I have come across both Glamira and thediamondstore. Now at the latter, they don't display quality in the sense of A, AA, or AAA. Just that the rings are from Thailand and that they're unheated, I've asked and they state that they do not grade the rings. What do you guys think, should this be a concern? I know my partner would like the design better from thediamondstore, but with Glamira you can handpick the quality. Obviously I want value for money and make sure she gets an adequate stone. (budget is around 2000 pounds)
