Platinum is among the best choices for people with metal sensitivities. It is typically used at 95% purity (950 platinum), with no nickel in the alloy.

A 3 carat stone is well above average and a great choice for someone who wants their ring to look expensive and elevated without crossing into the ostentatious territory you hit at 4-5 carats. A comparable lab-grown 3 carat stone can be found for $3,000 to $8,000 depending on quality grades. The price difference at this size is extraordinary, which is one of the most compelling reasons couples choose lab diamonds for larger center stones.

At this size, 3 carats puts you in a category most people only dream about. It delivers drama and luxury without crossing the line into impractical.
