Common Jewelry Restoration & Repair Questions

Can you repair my ring?
While our GIA Certified Gemologists and restoration experts can repair rings of all types, some pieces may be too badly worn or damaged to fix. The only way to know for sure is to visit our downtown Portland office for an evaluation. No appointment needed, just stop on by.

Do you only repair jewelry purchased from Malka Diamonds?
We do not! While we love working on our own pieces, we work on jewelry purchased anywhere. So long as we think we can fix it, we’ll try our best to restore your piece to its natural beauty.

What is a GIA Certified Gemologist?

The Gemological Institute of America, or GIA, is a non-profit institute focused on gemology education and research. A GIA Certified Gemologist has completed an extensive full-time program that includes both classroom study and hands-on training. It is the highest certification available for the profession. 

Can you appraise or grade my ring?
We can! Our GIA Certified Gemologists are always available to appraise or grade your jewelry! 

How much does it cost to repair jewelry?
We don’t have a set price list since every piece and every situation is different. We’ll evaluate your piece for no charge and offer you a quote for the service that’s needed. Generally speaking, however, our prices tend to be super competitive and lower than most other Portland jewelry stores.
