Is my price fair?

I got an 18K Solid Gold Rope Chain 2.5MM and 22”. It’s 12.5 Grams and I’m pricing it at $1800. Is my price fair or am I overcharging? I keep getting lowballed but I’m trying to follow the price of gold with a slight charge above. I’m trying to see if I keep getting lowballed because I’m overcharging or is it them?

I AM NOT SELLING HERE*

Just a question*
