What size of diamonds in a 3 stone ring?

I am getting a 3 stone diamond anniversary ring.
I want the centre stone to be .60 ct but how big should I get the side stones? I do want the centre stone to be bigger. Blue nile suggests .30ct each for the side stones but I wasnt sure if that was too small.

The rule with center stones and side stones is that the diameter of the side stones should be approximately the same size as the table of the center stone. In rounds, table sizes are typically between 55% and 60% of the diameter. The diameter of a 0.60 is usually about 5.5 mm. SO the diameter of your side stones should be about 3.2mm. 3.2 mm diamonds are about 0.12 ct each. But this is more of the classic “side stone” look and not the “3 stone ring” look. The 3 stone look usually has larger side stones that aren’t totally dominated by the center stone. A typical 1 ct total weight 3 stone right will have a 1/2ct center with two 1/4ct sides. So you might want to match your 0.60 with heavy 1/4s (0.27/0.28), or even a light 1/3 (0.30/0.31ct).

Enjoy the gift!
