Here is a pair of my collection, 6.5 x 6 mm and 8 x 6.2 mm (star, perfectly transparent) both untreated.
Argentic photo, you can better see the luminosity and true color.
Do you like these ?
Indeed, the facetted one was certified by one of the most conservative lab as a pad so it''s the most real padparadsha, in person you can''t tell if it''s more pink or more orange...
That''s really sorry you can''t see their color...
