Diamond terminology

Following a discussion on Facebook, what is the name for where the
pavillion facets meet on the bottom, the point where they meet.

Is that a trick question? Technically there should be a tiny facet,
which is called culet or culette. The facet is octagonal, so there
are 8 corners where pavilion facets meet. Each corner is a common
point to culet and 2 pavilion facets, which meets requirement for
definition of a vertex.

Hi Richard,

That would be the “culet”.

I know I’m in Australia, when I pronounced “culet”… “culay”, and
my teacher pronounced it “cul-let” :smiley:

Here’s a link anyway :-

Do you mean if there is not a culet?

Hello Richard,

This point is named “the cullet” If a diamond is cut correctly, this
point is exactly the center of the stone where all angles from the
paviljon finish in one symmetrical point. For chipping isue’s this
point is often minimal flattend and polished. The name cullus is
derived from the latin word “culus” which means “anus” pointing to
the very last part where everything comes together. No further
explanation needed I think -)

Have fun and enjoy

I was taught that it’s called the culet.

Richard,

I am thinking you mean where the two bottom halves" using diamond
cutting terms" meet??? Would be called facet junctions.

Ah, you’re the sly one, eh? The point ot which you refer, If having a
facet, no matter how slight, is the culet. If no facet then it is a
"closed culet"

The point at the bottom of the pavilion is the culet. If there is a
flat facet at the bottom, as in many very old diamond designs, it is
the culet facet.

cullet is the term and is usually cut at a slight angle so you do not
have a true point. Why I don’t know but have a few guesses in mind.
