![]() ![]() Before purchasing a diamond, you can see if it’s eye-clean or not using our 3D preview too. Eye-clean diamonds generally have excellent sparkle, assuming they’re well-cut. Clarityĭiamonds with low clarity may have imperfections that stop light from reflecting and refracting properly. It’s one of the optical properties of diamond that reflects its beauty and value, and by extension, its price. A brilliant cut, like a radiant or round brilliant, has lots of facets and lots of sparkle. Diamond brilliance refers to the white light reflected off of a diamond. As a rule, more facets means more sparkle. Brightness is the objective part of brilliance because it is something that can be. Sparkle is lost and you get a dull, lifeless diamond. In diamonds, brilliance is the combination of brightness and contrast. Light escapes through the side and bottom of the stone. Facets are positioned in a way that reduces scintillation. With a poorly cut stone, the opposite is true. The amount of light reflected and refracted through the crown is as high as possible. Pavilion depth is just right, keeping as much light inside the stone as possible. In a well-cut stone - “good” cut grades and up - upper and lower girdle facets are angled to maximize scintillation, fire, and brilliance. The simplest way to maximize a diamond’s sparkle is to use the 4C’s to your advantage. Brilliant cuts, like the round and the oval, tend to have lots of fast-moving scintillation. Step-cut stones with large facets, like the Asscher, tend to have lots of slow-moving scintillation.įast-moving scintillation means that light jumps from facet to facet quickly. Slow-moving scintillation means that light goes from facet to facet slowly. It tends to reflect more colored light than white light, especially with crushed ice stones. Moissanite tends to have more fire scintillation than diamonds. You can see more white light than colored light on them - again, in our experience. The Brilliance Ratio is the ratio between the area of a diamond’s face perpendicular to the line of sight and the size of its face parallel to the line of sight. Shapes with bigger crown facets tend to have more flash scintillation. Many diamonds sold by reputable jewelers have been graded according to the 4Cs and come with written diamond certification. The round brilliant cut is a good example it can have lots of colored light. In our experience, shapes with many small facets tend to have more fire scintillation. Flash scintillation refers to white light visible on a diamond’s crown.įire scintillation refers to colored light visible on a diamond’s crown. ![]()
