We save you up to $200 by choosing the right diamond color.
What is Color?
A diamond's color grade is determined by the degree of yellow tint it possesses, and those with a whiter, more transparent appearance are considered more valuable.
Our Recommendations
Don't underestimate the significance of G-H color range when it comes to diamonds - you can pocket up to $200 without compromising on noticeable quality.
If you want a halo or three stone diamond ring setting. Do not buy a center diamond rated I or J. You will notice the yellow tint in the center stone due to the smaller diamonds relative color.
