Hello everyone! I inherited this bracelet from my late grandmother. A jeweler confirmed it’s platinum on the front, 18k yellow gold on the back, with real diamonds and an emerald. Has no marks.
I was told it may be an Art Deco piece. Does anyone know:

1. approximate age/origin
2. estimated diamond & emerald carat
3. whether it looks high quality or from a known maker
4. if it’s worth getting certified/appraised
5. Would love any info about the style or history. It’s a family heirloom 😊

I inherited this bracelet from my late grandmother and would love to learn more about it. I really love and I wear it for special ocasions. It appears to be an Art Deco piece with platinum on the front and yellow gold on the back, set with diamonds and an emerald. No marks on it, however a jeweler has already confirmed that it is made of platinum and 18k yellow gold, and that the stones are genuine precious stones.

The craftsmanship looks very detailed and delicate. I’m curious about:
Approximate age/period. Whether it looks authentic Art Deco. Possible value range
Whether it would be worth getting certified/appraised and by whom (GIA, local jeweler, etc.)
Any insights would be greatly appreciated.
