Hi Orchid,

Is there a mathematical formula for computing what size tubing would

be the correct size to make a tube setting for a trillium stone.

Thanks, Vince LaRochelle

Perimeter of a stone should equal to circumference of the tubing

which is approximately diameter times 3.

Mathematically it is 2 *Pi*r - r - radius, Pi - 3.14

I think youâ€™ll find you need to add a bit over formula. Each corner

requires additional material to go around its radius, over and above

the calculated perimeter.
