24KT Gold India Style Necklace

I have a 24Kt Gold India style necklace. It weighs 33.3 grams and is 16" to 18" with very beautiful delicate gold work. It has a lot of tear shaped dangles with twisted bordered edges. The centered focal point has a heart like shape on the largest section.

I had a test done on it, and it is 24KT, with no markings, so I assumed it must be older, I have had it at least 15 years maybe longer. I do not know what to ask if I wanted to sell it. I do not have a photo to send as it is in a safety deposit box. Can you give me an approximate value?
