BluMenthal Jewelers


As you may have heard, Blumenthal & Co has retired after 44 years of serving the San Diego community. Before Guy and Pat retired, they chose Diamonds Forever as their favorite jeweler to continue caring for their valued clients and friends.


Hi, this is Jenny Seligmann of Diamonds Forever. I grew up in San Diego with an appreciation for cultural art and natural beauty. From this seed, Diamonds Forever was born more than 18 years ago.

Diamonds Forever is a woman-owned and led collective of gemologists, designers, and craftswomen. Weaving together thoughtful craftsmanship and spirited design ~ we create unique and deeply meaningful jewelry. Our specialties include custom engagement rings, heirloom redesigns, and antique restorations. Our work is locally handcrafted by an extraordinary team of artisans, each with their own focus.

I met Guy years ago, as we both worked in the jewelry industry. We hit it off immediately and became fast friends after discovering that our work ethic was similar. Guy and I highly valued attention to detail and had a high regard for craftsmanship. Pat and I shared a love for one-of-a-kind pieces and an excitement for custom design.

As Guy and Pat prepared to retire, they offered us this incredibly generous and once-in-a-lifetime opportunity to continue their legacy. In October 2022, we relocated to the former Blumenthal location on Date Avenue. Diamonds Forever is thrilled to now be a member of the La Mesa community. We look forward to meeting you.
