The approximate
carat weight of the
diamond in your
heart solitaire diamond ring can be calculated using measures like width, depth, and length. The formula for calculating the
carat weight using these attributes is:
Carat Weight = Length x Width x Depth x 0.006
Length: It is the distance from the pointed end to the farthest point on the cleft of the
stone.
Width: This is the measure of the widest part of the
stone.
Depth: Depth is the distance between the lowest point at the bottom of the
heart stone to its topmost
facet.
Example
If you have a
heart cut diamond with length and width 5mm each, and depth
3mm, then the
carat weight would be as follows:
Carat Weight = Length x Width x Depth x 0.006
Carat Weight = 5mm x 5mm x 3mm x 0.006 = 0.45 ct
While calculating this, the value obtained would not be very precise, as you can expect an estimation error of +/- 10 to 15%. In the above case, the
carat weight of the
diamond could be anywhere between 0.40 to 0.50
ct.
