Ideal Round Brilliant Diamond Proportions 💍
1 min
I recently got engaged and finding the right diamond for the engagement ring was tricky.
The cut of the diamond is one of the most important factors in determining its ideal dimensions and proportions. Each cut has its own ideal proportions that are designed to optimize the diamond’s brilliance and fire. I opted for a round brilliant cut diamond and found the below table to be very helpful in filtering through diamonds.
