Should I just use the formula for an oval stone ((HxW/2)+ width of bezel wire)x3.14), but would I have to allow for the points.
Good question! I don’t know of a formula to use to calculate the length of a marquise bezel.
Personally, I’d go low tech and get a ball park estimate by bending wire around the stone and dive into making it. On one pointed end, I’d score and bend the bezel to create a point. Then I’d wrap the bezel around the stone. Where it overlaps on the other side I’d file a mitered joint to match the other pointed side and solder it closed.
There’s probably a zillion ways to do make this bezel.
Let’s see what others suggest.
Thanks for asking!

Hi,
you can also use waxed dental floss, around the stone, to get an approx measurement…ir…
if i recall correctly, you can take length plus width, divided bt 2, then multiplied by pi 3.14, to get a diameter (length)
if you think about it, lets say the width is 6mm, and you are going to wrap 1mm wire around it…the width Outside diameter would be 8mm
6+1+1= 8
if you are considering cutting a seat, then 1/2 the metal thickness each side, for example
6+0.5+0.5= 7
calculate for Outside length plus outside width, divided by 2, then multiply by pi 3.14, to get the length of metal…(i think)
but i would add extra…to help bend…bend the metal with your fingers, using the pliers just as a fulcrum…dont bend with the pliers…i believe that will create a gentler curve…
let us know how it works out…
you can mark metal with sharpie or scribe

I make bezels for marquise shape by bending the bezel into an arc that fits on the side. Cut two arcs longer than the side. fit them together so the stone fits nicely. solder the ends and cut off the extra. The soldered end protects the fragile points.
