Quick and Easy Buying Guide

Carat weight: 1 carat = 200 milligrams = 6.5 mm diameter. Doubling weight doesn't double diameter.

Diamond clarity: FL/IF/VVS/VS = super expensive, near perfect. SI = best value if you can check a photo for obvious inclusions (defects).


Color: D-G = colorless, expensive, only if you have money to burn. H-J = best value. Can go lower in gold metal settings than white metal.

Cut: Better cut ratings let more light into a diamond, making it sparkle more. Very important property, don't skimp here.

Set a budget and minimum cut (Premium). Go J color for gold and I/H for white metals. Go searching for SI1/SI2 clarity diamonds at James Allen. Pick a diamond with small/no inclusions. Choose a ring setting and buy it risk-free (60-day returns).

Gemesis Colored Diamonds

Gemesis is a fairly recent diamond company specializing in creating artificial colored diamonds.

They supply diamond stores and other companies with wholesale quantities of colored stones, which are then customized to suit that particular store’s collection.

The company literally grows the diamonds in a specialized laboratory setting, starting from a “seed”.

Because these diamonds have been grown artificially in a laboratory setting, they are not natural diamonds. They are however genuinely the diamond material.

This clearly differentiates them from synthetic or imitation diamonds such as cubic zirconias.

If you're interested in getting a diamond from Gemesis, you have to find a store that offers the stones. You can look up Gemesis on the Internet and find out a list of stores that stock their stones.
