$10-11k is more than enough for a 1ct round diamond. The 1ct G VS2 below would be a nice starting point since it would work with whatever ring you have in mind. You could just get that and call it a day, but if you want to go further then it’s about your priorities – what kind of metal for the ring (i.e. would it be worthwhile trading off color), would you prefer a larger diamond within your budget vs. maximizing savings, would you be OK with higher fluorescence?
