Three things are important to determine your purchase choice and price.

Namely the color of the diamond: D up to J.
This is white up to light tinted white.

The internal purity of the diamond: FL up to SI 2.

And the size of the diamond: 0.30 Ct up to 3.00 Ct.
This is +/- 4.3 mm up to +/- 9.1 millimeter.
