My 18k gold chain’s clasp broke. Local jeweler quoted $70. Does that seem reasonable?

Personally thought that it might be a bit cheaper since it would only involve removing the clasp and replacing it (possibly with a cheaper one).

Happy to pay if it’s worth it since the chain has sentimental value, and the jeweler has good reviews. Does anyone have any thoughts on if it was correctly priced?

UPDATE: Thought I'd update this post incase someone comes across it. It ended up costing $80 but I went through with it and my chain is officially fixed!
