they’re more expensive because they are cut more to perfection. the inexpensive ones are real, but are flawed. that’s the difference, greater price, better diamond. but it’s not a very big difference to be able to tell. some sparkle more maybe just by the lighting or they were polished more recently. to purchase, the cost depends on how perfect you want the diamonds and how big you want them. it all depends on what your looking at
there is actually a grade of diamond. 4 c’s
The 4Cs diamond guide is provided to consumers as a reference for evaluating diamonds. The four most popular factors used to measure diamond quality are cut, color, clarity, and carat weight.
Cut, more than any other quality aspect, gives the diamond its sparkle. A diamond gets its brilliance and scintillation by cutting and polishing the diamond facets to allow the maximum amount of light that enters through its top to be reflected and dispersed back. When all the angles are correct, the light that enters is dispersed back through the diamonds top facets
Shallow Cut Diamonds
When a diamond is cut too shallow, light leaks out of the bottom, brilliance is lost and the diamond appears watery, glassy and dark. A diamond with these characteristics is referred to as a “fisheye”.
Deep Cut Diamonds
When a diamond is cut too deep, light leaks out of the sides, brilliance is lost and the center of the diamond will appear to be dark. A diamond with these characteristics is referred to as a “nailhead”.
