Gemstones We Buy Serving Santa Rosa, CA, and Sonoma County
North Bay Rare Coin & Jewelry buys a wide range of fine gemstones from sellers throughout the Santa Rosa, CA, area. The team accepts both loose stones and gems set in fine jewelry, estate pieces, antique settings, and designer mounts. Accepted stone types include:
▸ Diamonds, including round, brilliant, cushion, and vintage cuts.
▸ Rubies and sapphires, whether natural or accompanied by laboratory certificates.
▸ Emeralds, including Colombian and Brazilian-origin stones.
▸ Alexandrite, prized for its rare color-change properties.
▸ Tanzanite, aquamarine, and other fine-colored stones.
▸ Estate and antique gemstone jewelry from any era or region.
Sonoma County estates often include heirloom jewelry passed down through generations of Wine Country families, and many of those pieces contain certified or uncertified colored stones that may carry real collector value. Whether the stone is set in a Victorian brooch, a mid-century cocktail ring, or a modern platinum solitaire, the team can assess it accurately. You do not need appraisal paperwork to get started.

What Types of Gemstones Do We Buy in Santa Rosa, CA?
As a dedicated gemstone buyer in Santa Rosa, CA, the team buys virtually any fine gemstone with collector or resale merit. Loose stones are welcome, and so are gems still set in gold, platinum, or silver mountings. The distinction matters because some stones are worth more removed from their setting, while others carry greater value as complete, signed pieces. Principal buyer Greg Krill has evaluated hundreds of millions of dollars in rare coins and fine jewelry throughout his career, and that depth of experience extends directly to gemstone valuation. Whether you have a single loose sapphire or an entire estate collection of antique jewelry from a Healdsburg or Bennett Valley property, the evaluation process is the same: thorough, honest, and at no charge.
How the Gemstone Buying Process Works
Every gemstone receives a professional, no-pressure evaluation from a qualified gemstone buyer.
The process typically follows four steps:
1. Schedule a private appointment by calling (707) 287-1919 or visiting North Bay Rare Coin & Jewelry to book directly.
2. Present your gemstone or jewelry piece, along with any certificates, GIA reports, or provenance you may have. No paperwork is required.
3. Receive an expert assessment, where each stone is examined for color, clarity, cut, carat weight, and current collector market demand using real-time data.
4. Get a competitive, transparent offer with no obligation to accept. Payment is made immediately when you agree.
Appointments can be arranged as a confidential home or office visit for sellers in Santa Rosa, CA, Sonoma, and Marin County who prefer privacy.
Loose vs. Set Gemstones: Does It Matter?
Both loose and mounted gemstones can be sold to our gemstone buyer team. Loose stones offer a cleaner look at a gem's color and clarity, which may work in the seller's favor. Set stones, especially those in antique or designer mountings, can be worth significantly more as complete pieces if the setting itself has value. The team evaluates both the stone and the setting to ensure you receive a fair offer for the whole item, not just the raw gem weight.
