First off congratulations! We'd be glad to help with sizing your ring. We have great jewelers with full-service repair shops at all three locations. Sizing starts at $45 for white gold rings, $55 for yellow gold, and $70 for platinum. The exact price depends on how wide the band is, how many stones are set in the ring, and how much it needs to be sized, but in most cases doesn't exceed $100. Our official turn-around time is approximately 10 days, but our shops generally run ahead of schedule, and we're glad to try and accommodate if you need something sooner. Feel free to stop by any of our locations, and we're glad to look at it with you and confirm an exact price before any work is done. If the ring was purchased at Polly's there is no charge.
