Miriam Haskell is a fabulous designer. She created a very versatile 52" necklace. It can be layered as pictured. You could even add a fancy brooch to upcycle the piece. If you ever run across a Miriam Haskell piece hang on to it because they are harder to find and more costly.
Whenever I am shopping for items to sell, I look for tags on the necklaces because that is often a signed piece. Signed pieces are easier to describe and sell because often there are people that like a particular designer.
If the signature is not on the tag is will usually be found near the clasp on or the clasp if it is a signed piece. When it is in one of these spots it is often super tiny so you need a magnifier.
I found a "loop" in the coin section at the bookstore. It is a 16x powerful magnifier that folds up. When I worked the flea market, I learned about these type of magnifiers because a male shopper had one hanging from a lanyard around his neck. He used it to inspect the pieces that he purchased.
I try not to think of the pieces I may have underpriced and still underprice due to my lack of knowledge. I focus on each aspect of this journey as a new learning experience.
When photographing a necklace, try not to overlook the clasp. It can be an indicator of the age of the piece. A person who is a an avid jewelry collector will look for these type of details. Others will have a better idea of what they are purchasing so the outcome is often favorable. Close ups of the piece are essential for indicating more subtle details that cannot be noted in the average picture.
Right now I am focusing on learning how to list items as accurately and efficiently as possible. I plan to have a notebook on my desk just to jot down these ponderings so that I can research them in my spare time. I can't express how exciting it is to learn a whole new "area." I have focused so much of my time on classroom best practices when I was teaching that I missed out on learning about this type of topic. I really appreciate the layers of knowledge that are required in learning about jewelry. Aside from types of clasps, types of beads, types of chains, types of gems, types of metal, etc...There are also oodles of designers to learn about and what influenced those designers, AND there is all the historical periods. Oh my it is overwhelming. That is why I want to share, share, these tidbits as I learn them.
