I read the post where Mara helped someone put together diamond studs. Could you help me as well. I can't decide between .607 VS2 G (Lot no. S246067 and S24606 and .46 SI1 E (Lot no. I239409 and I239511. I would like total carat weight to be around 1.0 - 1.25. I'm not sure if theres a noticeable size difference between the .46 and .60 to make it worth the price difference.
