At Suranas, we are captivated by Diamonds, and have a large collection of the world’s finest Diamonds. Our curiosity has made us experts, and we would like to share some of that knowledge with you.


A Diamond owes most of its beauty to nature, but it is the Diamond cut that determines the all-important sparkle factor. Most popular is the round brilliant cut but there is a wide range of shapes for engagement rings that we can help you select from.

Oval Cut

Brilliant Cut

Pear Cut

Marquise Cut

Cushion Cut



A carat is measured based on the weight of the diamond, and not of size, as is often supposed. Even though Hollywood has made large solitaires popular, the cut is the most important factor as it maximises sparkle. FUN FACT: Fancy-shaped Diamonds can appear larger than their actual diamond carat weight size.



This is generally a good guide to the unique physical properties of diamonds. All Suranas Diamonds are analysed and graded for quality by the Gemological Institute of America (GIA) or by the International Gemological Institute (IGI).
