Not only are we professional jewelers, we’re downtown Portland’s leading destination for precise, certified jewelry appraisals (including insurance appraisals). Count on Malka Diamonds and for not only an honest, professional, no-obligation assessment of your jewelry’s value, but also a thoughtful explanation of the appraisal process. Our founder, David Malka, is one of three graduate gemologists in the greater Portland area. As founder of Independent Gemological Services, he’s earned a reputation as the region’s premier diamond authority. David’s the final word on a gem’s value and the steady stream of diamond brokers you’ll find seeking David’s opinion is a testament to one obvious fact: This isn’t his first rodeo. The man knows diamonds and jewelry.
