What is Gem Weight?

A gem weight is defined as the total mass of a gemstone based on the physical characteristics of length, width, depth, specific gravity, and shape. This calculation helps in determining the carat weight of a gemstone.

Example Calculation 1

Let's assume the following values:

Step 1: Multiply the length, width, and depth:

\[ L \times W \times D = 10 \times 5 \times 3 = 150 \]

Step 2: Multiply by the specific gravity, shape factor, and weight correction factor:

\[ GW = 150 \times 3.52 \times 1.0 \times 1.0 = 528 \]

So, the gem weight is 528 carats.

Example Calculation 2

Let's assume the following values:

Step 1: Multiply the length, width, and depth:

\[ L \times W \times D = 8 \times 4 \times 2 = 64 \]

Step 2: Multiply by the specific gravity, shape factor, and weight correction factor:

\[ GW = 64 \times 3.52 \times 1.0 \times 1.0 = 225.28 \]

So, the gem weight is 225.28 carats.
