you buy.
Carat
Carat measures weight. Compare proportions and cut alongside carat to understand how a diamond will look in its setting.
Color
D (colorless) through H (near-colorless). All Celestyn stones D-H grade. Anything below H shows warmth.
Clarity
Clarity is assessed under 10x magnification. We can help you choose a stone with the appearance and clarity grade you prefer.
Cut
The only C controlled by human craft. Ideal and Excellent cuts only. This is where brilliance lives.
Two cities.
One standard.
Celestyn Jewels is a partnership built on a simple thesis: the diamond supply chain has too many hands, and every hand takes a margin. We removed them.
