Enter a value for all fields

The **Old European Cut Diamond Weight** calculator computes* Old European Cut Diamond * the approximate carat weight of a Old European cut diamond based on the average diameter, depth and girdle thickness factor.

**INSTRUCTIONS:** Choose units and enter the following:

**(V) Vertical Length****(H) Horizontal Width****(D) Depth****(T) Girdle Thickness Factor**

**Old European Diamond Carat Weight (Wt):** The calculator returns weight of the Old European Cut diamond in carats. However, this can be automatically converted to grams or other weight units via the pull-down menu. **Note:** Both the vertical and horizontal are entered to compute the **average diameter** in case the diamond face isn't precisely symmetrical.

The formula to estimate the carat weight of an Old European Cut diamond is:

Wt = vLENGTH * hWIDTH * DEPTH * 0.0064 * wc

where:

- Wt = Carat Weight of an Old English Diamond
- vLength = Vertical Length of face
- hWidth = Horizontal Width of face
- Depth = Depth of side (see diagram)
- wc = Diamond Weight Correction, which is between 1.00 and 1.08 depending on the girdle thickness and mean diameter.
- Mean Diameter = (WIDTH + LENGTH)/2
