A lady has asked me to set two stones her great-grandmother kept into rings.
She is not sure if they are glass or amethyst (took them to a jeweller who 'didn't know', but they are def. cut by a hobbyist - cutting is pretty uneven and many of the corners are rounded etc). They're pretty large - there is an oval stone approx 20mm long and a heart shaped stone approx 18 x 12mm. Both stones are quite deep. The underside of the heart is uneven and goes into a rough point.
I want to make a double gallery collet for it. I've made the two heart shapes, now have the four prongs to attach.
How do i do this and get the angles correct without a)crying and b)crying more?
All advice appreciated hugely x
