I would like to purchase a semi-mount with trapezoid side diamonds - I know it''s a shot in the dark, but I was hoping to find an existing mounting to save $ instead of going the custom route...
This would be for an 8mm square cushion blue sapphire.
Go to www.thefacetscollection.com. Pick "The Facets Collection," then "Engagement Rings, then "Solo Settings" and go through the pages. There are a few with traps of different sizes (more in the end of the pages of settings than in the beginning).
Not sure if these will work but at least it''s worth a try!
