Does anyone have an original early 20th cent. white gold (preferred)
or platinum filigree mounting with a hexagon shape crown that will
hold a 6.1mm Old European cut Diamond.
If not my client might consider a reproduction one if it looks like
an original one or one with a different shape top.
If one is available that needs work or held a smaller size and I can
replace the top plate or open the current one to fit a larger size
that would be OK.
