Featured What would you call this 18k & diamond cluster pendant

Good morning y'all. I traded for this little stunner recently and haven't had much luck finding something similar online. It's marked and tested 18k (8g) and the diamonds are genuine. Take a look and let me know what you think! I'd really appreciate any guesses as to the age of it.

 

The front wants to be old, but the bail and the hallmark don't. Can we see the rest of the back?

 

is it hollow..

 

I can't say for sure the bail is original, it's a slightly lighter tone of gold. And but of course.

Nope, it's solid.

 

IF I remember correctly,werent brilliant cut diamonds later ? I think it has a slightly deco feel,so maybe 20s-30s?

 

Beautiful diamonds. I think your pendant is too recent for me to be able to say much about it. Others may know.

Yes, the modern brilliant cut was invented in 1919, by Belgian mathematician Marcel Tolkowsky. And you're right, this is later. Also later than Art Deco, imo. Post 1940, and possibly a few decades later, with that double bail ring.

 

Are you sure it isn't hollow? 8g isn't very much.
I know next to nothing about US coins, how big is it?

 

Thank you for your comments! I'm quite sure, the measurements are 24mm by 15mm, and it's 2mm thick or 5mm including the setting. So not heavy in general but for it's size it feels quite substantial in the hand.

 

Thank you.

Sometimes a hand is a good way to assess things.
