single vs full cut diamonds

Single cut diamonds began in the 1600's with just a few facets to catch the light. Consumers and jewellers have more recently moved back to single cut diamonds because of the shortage and cost of the diamonds today. Single cut diamonds can still refract light and when set properly, give a brilliance to jewelry in a more cost effective manner.




The difference between single cut diamonds and regular round brilliant diamonds is the number of facets (cuts). The classic round brilliant (full cut) will have 58 facets while single cut diamonds have 16-18 facets; 8 facets on top, 8 facets on the bottom and additional facets on the culet, facet or the crown. Single cut diamonds are small and usually under .10 carats. Some jewellers prefer to use single cuts on small stones because there are fewer cuts making the facets more visible compared to round brilliants having 58 facets within one very small stone.
