Gorgeous amber colored earring and necklace set

This was never used in the 9 years I’ve owned it, I bought this set at an antique/vintage store about 9 years ago. I just recently removed it from It’s original packing to try to sell . Has never been worn since I’ve owned it I don’t know about prior to me. Great condition, amazing color. Chain is 925. I have no idea what it’s made out of, I am just selling based off what I purchased it for.
