How much does it cost to replace a lost diamond?

Excuse me, I was wondering if you could provide some insight on the cost associated with replacing a lost diamond. I understand that the price can vary significantly depending on factors such as the diamond's carat weight, clarity, color, and cut. Could you perhaps elaborate on what these factors might mean in terms of a replacement cost? For instance, if I had a one-carat diamond with excellent clarity, color, and cut, what kind of price range might I be looking at? Additionally, are there any other expenses that I should consider, such as insurance or appraisal fees? Thank you for your time and assistance.
