General Purpose Select Premium
General Purpose stones, although in some cases may be reset, are referred to as "throw aways". These are lesser quality stones than Select or Premium diamonds and therefore have less dressing time expectancy.  Select diamonds are better then General Purpose stones but are less expensive than Premium because they have fewer cutting edges. Select stones approximate Premium quality, but have fewer points and therefore cannot be reset as many times. Premium diamonds are specially selected diamonds for their shape and structure. These diamonds, because of their many points, may be reset several times which more than pays for the higher cost.
