Designer's Mark I.D

Hi, all; I have a 14k earring with a missing stone. It should have 14
square cut 2.4 - 2.5mm white stones, but one fell out and customer
would like it matched. Problem is, I don’t know what they are. It’s a
seemingly quality piece of unknown origin, purchased in NY. There is
a carat mark of “K14”, and a designer’s mark on a plate soldered to
the underside of the earring. I was hoping someone could ID it or
send me to a resource that could help me identify it. It is a simple
diamond silhouette shape with 2 diagonal lines running through the
girdle. (I tried drawing one with the keyboard but the e-mail system
messed the image up). I could get a CZ replacement but she wants to
replace with a diamond if that’s what they are. If I can ID the
designer I can find out for sure. Thanks for all your help.

Sounds to me like you need to invest in some gemological equipment,
like a diamond tester for starters. Trying to identify a gemstone by
locating a maker by their mark is sort of like driving from Florida to
Maine via California.

Hi Jim,

You could take it to a graduate gemologist (GG). He should be able
to id the stone for you. Another option is most any jewelry store that
has a diamond tester. This is a device that will tell you if the stone
is a diamond or not. Testing it with one of these only takes about 1
minute & is a positive test in this case because the piece in question
was made long before synthetic moisannite was available.

If stone isn’t a diamond, A GG should beable yo tell you what it is.


Jim, Don’t you have a Diamond tester? The first thing I would do is
test it with a diamond tester then see what other possibilities the
stones could be. David
