About Soriano Custom

Soriano Custom is a California-based, woman-owned boutique jewelry studio specializing in bespoke design, ethically sourced lab grown diamonds and gemstones, and modern heirlooms crafted with intention. We blend our deep appreciation for beautiful jewelry with a commitment to exceptional quality, creating pieces that feel personal, distinctive, and built to last.

We offer three core categories of work:

Custom designed fine jewelry — curated essentials such as studs, bands, solitaires, and tennis pieces, chosen for their quality, value, and everyday wearability.

Diamond sourcing — a concierge service that locates exceptional stones, including antique cuts and specialty facet patterns, paired with transparent guidance throughout the selection process.

Commissioned jewelry — fully bespoke pieces tailored to each client’s style, budget, and timeline.

Soriano Custom is intentionally small, relationship-driven, and detail-obsessed. Every project receives personal attention—from stone selection to CAD design to final inspection—ensuring clients feel informed, cared for, and part of the creative process.

At its core, Soriano Custom exists to make meaningful jewelry for real people: pieces that celebrate milestones, honor loved ones, and become future heirlooms without ever feeling mass-produced.
