This is an auction site built with Django where users can create listings for stones, place bids, watchlist items, and leave comments. The owner of each listing can close the auction, selling the stone to the highest bidder. Bidding and other functionalities are restricted based on the auction status.

Listings: Users can create listings for different types of stones.

Bidding: Users can place bids on active listings. Only bids higher than the current price are accepted.

Watchlist: Users can add listings to their watchlist for easy tracking.

Comments: Users can leave comments on each stone listing.

Auction Closing: The owner of the listing can close the auction, awarding the stone to the highest bidder.

Error Handling: Bidding is restricted after the auction closes, or if the bid is lower than the listing price or a previous bid.
