Hi all - I got a chance to see the large, 13.something carat Eight
Star Diamond that is touring the country yesterday. Very nice
diamond - I really liked the cut, and the way it reflected color and
light back out. Gorgeous. However it was in what I considered to
be a pretty clunky setting, and in discussing this with the clerk
(they offered to re-set it at no charge in any setting I wanted if I
bought it - for $2.3 million they should!!) she mentioned that
all the light enters through the top of the stone.
I am fairly new to setting stones, and don’t deal at all with
diamonds, but I have a couple of questions that haven’t been
completely answered with a search of the archives. When I set
colored gemstones I do feel that a completely closed setting results
in the stone reflecting less light back out at the viewer. Is this
true, or a misperception on my part? Or is there a difference
between diamonds and colored Or is it a difference in
the quality of the stone and its cutting? I don’t see how, from a
purely physical standpoint, light can NOT enter from the sides and
bottom if they are open. Maybe I just don’t understand the physics
of the facets and how they reflect light back out?
Clarification would be greatly appreciated - as I design more
settings myself, I need to know more about how to maximize the
brilliance of the stones.
