[Looking4] Pear shape crown head

Hello to all…

I am looking for a 10 prong (or so) head for a pear stone
measuring. 8.9 x 5.5.

This is am old ring that I either need to re-prong all prongs or
what makes more sense, is to put in a new head…if I can find one
that matches verses a newer head with a v-prong at the tip and 2
other prongs. This type just wouldn’t fit into the old style of the

This is an 18kt mounting but I am willing to put in a 14 kt if I can
not find one with a higher carate.

I have looked in the 'ordinary" catalogues…Any suggestions

Much thanks,
