Weight & Measure
Diamond weight is expressed as Carats. Nexus Diamond Alternative and Moissanite stones are expressed as Diamond Equivalent Weight (DEW), as the actual carat weight of these stones vary from diamonds. Stones listed with DEW will match the proportions and measurements of a diamond with the same carat weight. So, the overall aesthetics of a stone listed with Diamond Equivalent Weight will look the same as a diamond with the identical carat weight.
Lab Grown Diamond
A lab grown or man made diamond is a diamond. There is no scientific difference between mined diamonds and lab grown diamonds. Man made diamonds possess the identical physical, chemical and optical properties as mined diamonds. Like a rose grown in a greenhouse and one grown in your front yard. The difference is simply origin. Learn More.

Diamond Nexus uses a patented diamond alternative, that is neither moissanite nor cubic zirconia. This stunner recreates that Meghan Markle sparkle.
Diamond Nexus jewelry uses the man-made alternative Nexus Diamond™ to bring you all of the beauty of a natural diamond, without the cost.
