Diamond Cut
Diamond Cut refers to how well proportioned a diamond is. For example, what percentage of a diamond’s diameter is its depth? What are its various angles and how do they interact with one another? While these may seem like esoteric questions, these are the essential factors that determine how beautiful your diamond will be. Differences in Diamond Cut greatly impact sparkle, aesthetic appeal and value of a diamond. The factors affecting the price of a diamond include:
- Proportions (table, width, depth)
- Symmetrical Facets (the mirrors, windows and steps of a diamond)
- Brilliance (brightness of white light reflection)
- Fire (dispersion of colored light)
- Scintillation (the flashes of sparkle when light moves)
- Finishing Details (permanent treatment and polishing)
Diamond Cut Proportions
Diamond Cut Proportions directly affect a diamond’s ability to reflect light and provide brilliance. Proportions are based on the ratios between size, angle and shape of each diamond facet. Various combinations of these elements impact how the diamond will interact with light, which determines its overall beauty and lasting appeal.
