what is a single cut diamond
How Chips and Single-Cut Diamonds Differ. Whereas chips donât really have a symmetrical shape, single-cut diamonds are round and faceted. What makes single-cut diamonds different from regular round diamonds is the number of facets. The classic round shape has 57 or 58 facets (this cut is also referred to as â full cut â), while the typical single-cut diamond has 16 or 18 facets.
