Business Description:
With nearly 30 years in the jewelry industry, our family-owned business specializes in custom design, expert repair, and one-of-a-kind pieces featuring rare and exceptional gemstones. Originally founded in 1986 as a wholesale gemstone company, we evolved as clients began requesting bespoke jewelry tailored to their vision.
Our expertise is strengthened by having a graduate gemologist on our team, allowing us to provide professional appraisals for natural diamonds and colored gemstones. We have sourced gemstones globally, including direct travel to Brazil, and have participated in major gem and jewelry shows in Tucson, Arizona for over 38 years.
After operating two retail locations, we now offer a more personalized experience through a private, appointment-only showroom. As the Constantine family, we are deeply committed to our community, actively supporting local initiatives through donations, volunteer work, and involvement with our organizations Paula’s Project & Sunrise Covina Rotary.
How Business Creates Value:
We provide clients with highly personalized, expert-driven jewelry services that go beyond traditional retail. From sourcing rare gemstones to designing completely custom pieces, we help customers create meaningful, lasting heirlooms. Our in-house gemological expertise ensures transparency, accuracy, and trust—whether for purchasing, redesigning, or appraising fine jewelry. Clients benefit from direct access to decades of industry knowledge and global sourcing relationships.
How Member Creates Value:
Through trusted relationships, thoughtful referrals, and collaborative client opportunities that help members grow their businesses, while members contribute by referring individuals who appreciate bespoke jewelry, rare gemstones, and a highly personalized experience

Custom Jewelry Creations
What sets us apart is the experience—we offer a more personal, tailored approach where every client receives individual attention. We believe jewelry should be a personal expression of you, which is why we specialize in custom design and collaborative creation.
A major part of what we do is our involvement in the Tucson Gem and Jewelry Show, the largest event of its kind in the world. We have been attending the show since 1986 and participate 3–4 times each year, bringing our own jewelry, designs, and expertise directly to clients. Many customers connect with us through Tucson and continue to reach out throughout the year with custom jewelry requests, making it an important extension of our business and long-term relationships.
