We are trained professionals and can provide you with quality jewelry repairs whether you purchased with us or elsewhere.


Here at Sigal Diamonds we offer free appraisals with purchase for our customers if needed. This is solely for the purpose for providing documentation to the insurer incase the item is lost, stolen or damaged. Some insurers may require additional certification.

We also offer appraisals for jewelry not purchased here at Sigal Diamonds, for a fee.


First, Sigal Diamonds professionally checks your precious jewelry to make sure all of your stones are secure. Once examined, your jewelry will be placed in an ultrasonic cleaner, which sends high frequency sound waves through a liquid solution to remove the dirt and buildup. Finally a high-pressure steam cleaner will be used to remove any additional buildup which will give back that brilliant sparkle.

Special Note: Never use harmful solutions (household bleach) or abrasives (toothpaste or other household cleaners). These products can erode some of the metals often used in jewelry.


Sigal Diamonds understands that with the passage of time, every day elements of life, pollution, temperature changes, the wearer’s skin and occasional knocks can wear away and possibly damage jewelry. We also understand the importance of being able to pass down your precious gems from generation to generation. Our commitment to you will be to help preserve your precious jewelry for years to come at no additional cost for the life of your purchase from Sigal Diamonds.

This service consists of:

  1. Jewelry Inspection

  2. Jewelry Polishing

  3. Jewelry Cleaning

If slight scratches are present, these will be removed with a felt disc and shining paste.

​Note: Rhodium Plated Jewelry is not included in the Polishing Service. Once a ring is polished the rodium would be removed. The above process can be completed at a small charge for having your piece re-rodium plated.

*Creations not purchased from Sigal Diamonds are not warrantied with this service.
