The Tapered Baguette Diamond Weight calculator computes the approximate weight of a tapered baguette shaped (cut) diamond based on the top and bottom horizontal widths, the length and the depth.TaperedBaguette.png

INSTRUCTIONS: Choose units and enter the following:

  • (TW) Top Width
  • (BW) Bottom Width
  • (L) Vertical Length
  • (D) Depth

Tapered Baguette Diamond Carat Weight (Wt): The calculator returns weight of the diamond in carats.  However, this can be automatically converted to other weight units (e.g. grams) via the pull-down menu.

The Math / Science

The formula for the carat weight of a tapered baguette diamond is:

       wt = L • (TW + BW) /2 • D • 0.00915


  • wt is the weight of the tapered baguette diamond
  • L is the vertical length
  • TW is the width of the top of the diamond face
  • BW is the width of the bottom of the diamond face
  • D is the depth or thickness of the diamond.

The formula makes an approximation of the volume of the diamond based on the dimensions and the shape.   It also accounts for the density of a diamond and combines the volume and density to estimate the weight.
