Clearness characterizes the inward considerations or potentially surface flaws that a jewel might have under 10 x (power) amplification. This is really FTC characterized. These considerations are uncrystallized precious stone or carbon seen as small dark spots in the actual jewel or they can be white like gas or air pockets or they might in fact be minuscule breaks called feathers. Clearly, a plume is certainly not an enormous break that goes from one side to another across the precious stone. That would be another person's stone, not yours.
Carat Weight is straight forward. What amount does it gauge? North of 1 carat? Under? There are 100 focuses to a carat like pennies to a dollar. A half truck is 50 focuses, a quarter 25 focuses, etc. Precious stones seldom are cut right on "the point", like say a 1 carat dead on. Typically a one carat would be a.94 up to a 1.07 carat. Weight and size essentially remain inseparable. Obviously, taking everything into account the greater the precious stone, the greater the cost. Trust it.
Being in the precious stone business for north of 25 years has shown the purchasers who settle on the most horrendously terrible choices are the people who don't have the foggiest idea what they are doing, or they learned to be "hazardous". Moreover, the people who have some essential seeing generally go with savvier choices getting a lot more prominent incentive for their cash.
