WHAT FACTORS AFFECT DIAMOND VALUE ?
Diamonds can be worth hundreds of thousands of dollars or mere hundreds, it all depends on their features. Similar to other valuable things like cars or houses, there are many different features that together define a diamond’s value, Like shapes, sizes, colors, clarity, polish, and other internal or external qualities
The core test of a diamond’s grade is usually made from the four C’s:
Colour
The value of diamond ranges from D to Z, where D is 100% transparent and Z is yellow. This is the measure of the amount of color in the diamond, where D is the most valuable as it causes more light to be reflected on the facets which create that unique sparkle that people are so attracted to.
Clarity
Clarity depends upon the absence of inclusions (internal) and blemishes (external) marks. The values range from FL to I3 or flawless to visible respectively, they refer to the number of marks, in which I3 is when marks are visible without equipment and flawless has none even with equipment. Sometimes damages to a diamond’s exterior or interior can only be seen with special magnifying equipment.
Carat Weight (ct)
The net weight of the diamond in carats.
Cut Grade
In diamond value estimators these range from excellent to poor, and refer to the cut quality and shape of the diamond – if proportional or not. Excellent cuts enhance the prism effect and reflect light better, and thus are more desirable
Shape
There are several popular cuts; the most popular is the round brilliant, then the “Fancy” cuts: heart, pear, oval, emerald, cushion, radiant, and princess cuts. Their popularity changes according to fashion trends in the industry.
Symmetry
Ranges from excellent to poor, and is graded on how the facets are aligned with one another; facets like the table, culet, crown, and girdle.
Treatment
Some diamonds are artificially enhanced to have better clarity or color, this can be detected by special equipment and these diamonds are considered less valuable than naturally clear or colored diamonds. Some treatments use fracture filling or HPHT for enhancement.
Fluorescence
Valued from none to very strong, and refers to the amount of shine under UV lights. The less shine the better, as it is caused by impurities.
Polish
Valued from excellent to poor, and refers to the degree of smoothness of each facet. Roughness can be spotted with specialized magnifying equipment.
