Thank you, Andrew, but as far as I can tell from the picture, the
clasp I am looking for is completely different. Ah, those
hard-to-draw word pictures!
Let me take another stab at it.
The clasp system I am interested in is typically used in pairs, to
make a decorative “bead” that holds a necklace together but can be
removed and replaced with another similarly equipped clasp, or the
clasp can be used on assorted strands with the right terminals. On
the strand, there is a male part, maybe a quarter inch
long–essentially, a wire with a specially shaped ball on the end,
usually at each end of the necklace. The clasp has a hole. When you
insert the “wire” part into the hole, you are compressing a spring.
When it is fully inserted, a slight twist causes it to stay in
place. This actually makes the clasp invisible. The parts can be
cemented into pearls, for example, for a “claspless” look. The
"ball" on the end of the stalk or wire must not be spherical, but I
didn’t really get a chance to examine this as I wished.
I’m not sure that I have seen this used by more than one company,
but the rep who showed one piece to me said it is from Germany, and
didn’t say that it is the artist’s special patent or any such. But
it may well be. Unfortunately, I cannot remember who the artist is.
They were pretty spectacular pieces, with gorgeous strands of
I can design something that would work similarly, but 1) my work
isn’t in the price range yet that would justify the time for all
that engineering and 2) I haven’t yet figured out how you get a
spring inside such an object after all heat work is done, so you
don’t anneal the spring (laser welding?). So I guess I’m saying, I
can picture how the innards would be arranged, but I’m not good
enough to actually make it.
So, if this rings a bell with anyone who may have a source, that
would be great!
