Custom Sapphire Sourcing in Petaluma, CA

At Lauren O Jewels, we specialize in sourcing exceptional sapphires in every shade and origin—from deep royal blues and vibrant teals to soft pastel pinks and golden yellows.

With more than 65 years of combined experience in the fine jewelry and gemstone trade, Lauren and Terry O’Sullivan bring unmatched expertise to every sourcing project. Together, they offer clients the rare opportunity to work one-on-one with a private jeweler who combines global gemstone connections with local, personalized care.

As an ASA-accredited appraiser and GIA Graduate Gemologist, Lauren provides advanced gemological insight and trusted evaluation, while Terry draws on decades of craftsmanship and design experience in fine jewelry. Their shared approach is built on integrity, education, and precision—helping you understand the nuances that define sapphire quality, rarity, and beauty.

The Sapphire Sourcing Process

Every sapphire is as individual as the person who wears it. We begin with a private consultation to discuss color preferences, shape, size, and intended use. Whether you envision a traditional blue stone or a rare peach or teal hue, we’ll curate options that meet your specifications and reflect your desired aesthetic.

Lauren and Terry personally source sapphires from reputable suppliers and gemstone dealers around the world, maintaining relationships built on decades of trust. From Sri Lanka and Madagascar to Montana and Australia, each stone is evaluated for its hue, saturation, clarity, and brilliance before being presented to you.

Our process is deeply personal. Clients are invited to compare stones side-by-side in our private Petaluma studio, learning firsthand how cut and tone influence sparkle and overall appeal. The result is a sourcing experience that is informative, transparent, and guided by experts every step of the way.

Ethical and Transparent Sourcing

Lauren O Jewels is dedicated to responsible sourcing and transparency throughout the supply chain. We work exclusively with partners who prioritize environmental responsibility, ethical labor practices, and verifiable provenance.

Knowing the story behind your sapphire adds depth to the jewelry you wear for a lifetime. Each stone is carefully vetted for authenticity, origin, and treatment, giving you the confidence that your purchase aligns with your values as well as your style.

From stone to setting

Once your sapphire is selected, we can assist with custom jewelry design and fine jewelry settings to bring your vision to life. Whether you prefer a timeless solitaire, a three-stone arrangement, or a distinctive bezel-set pendant, every piece is designed with balance, proportion, and longevity in mind.

Using CAD (Computer-Aided Design) renderings, we provide detailed visuals before production begins—ensuring that every detail reflects your personal aesthetic. Each piece is handcrafted in our Petaluma studio, combining traditional artistry with modern technology to create jewelry that feels both refined and personal.
