Looking for Jewelry manufacturer specializing in Light weight Diamond Tennis bracelet & Necklace.

The requirement of this job is very simple. I am in search of jewelry manufacturers in India who specialize in very lightweight gold and diamond jewelry, specifically in very lightweight tennis bracelets and tennis necklaces. If you are a candidate who knows or can assist with tying me up with these manufacturers, it will be a great help. To help you understand what is required, here is an example: • A standard tennis bracelet currently takes 9 grams of gold for 5 carats of diamonds. • I need a manufacturer who can produce a tennis bracelet using only 3 grams of gold with 4 carats of diamonds. I hope this helps with your understanding of what is meant by light weight. If you know any manufacturers, kindly get in touch. Thank you.
