Answer:
an artisan's lien.
Explanation:
Rick agrees to customize Melissa's wedding ring. The cost is $10,000. After the job is complete, Melissa refuses to pay. As long as Rick retains possession of the ring, he may seek to recover the cost of the labor with an artisan's lien. This is the legal right of an artisan to withhold a good or piece of work from its owner until it has been paid for.
