Answer: -It should not be a problem to get a low price on the setting. Try a small chain or "mom and pop" operation. Mention to them that the diamond is a family heirloom and so they should be sympathetic to your situation. -I would take a little time and save up the cash to pay for it outright. A simple setting for a stone likely won't cost more than a few hundred dollars. Watching your spending and possibly getting a side job will help you to reach this goal faster. This way, you won't feel pressured to go to a poor jeweler. Since this diamond is an heirloom, you need to be certain your jeweler is reputable.Good luck on your engagement proposal!!
