Diamond Haus Custom Jewelers announced that jewelry designer Addison Webster has successfully completed the GIA Diamond Grading Lab course hosted by the Gemological Institute of America at the American Gem Society campus in Las Vegas. The intensive five-day program, which she finished this fall of 2025, equips her with advanced scientific knowledge of diamonds, marking a key step in her professional development within the family-owned business established in 1997.
The company, which operates as a full-service custom jewelry provider, integrates this new expertise into its established workflow. Addison Webster, known for her artistic approach to design, sought to deepen her understanding beyond aesthetics into the technical aspects of gemstones. The course focused on the science behind diamonds, including their formation, grading criteria, and distinguishing features. Participants engaged in hands-on laboratory work, evaluating stones under magnification, identifying clarity characteristics, recognizing subtle color variations, and assessing how cut proportions influence brilliance. Training also covered differentiation between natural diamonds, lab-grown stones, and simulants.
This achievement enhances the precision available in the company's custom jewelry process. Clients begin with consultations where ideas are discussed in detail. Designers then create CAD renderings informed by comprehensive gem knowledge. Wax models are carved, pieces cast in selected metals, gemstones set with accuracy, textures applied, and final polishing completed in-house. Addison Webster's training supports smarter stone sourcing and design decisions that honor the unique properties of each diamond, benefiting projects ranging from bridal sets to personalized heirlooms.
The business originated as Fort Thomas Jewelers, initially specializing in repairs and manufacturing for wholesale clients across local and national markets. It rebranded to Diamond Haus Custom Jewelers to emphasize retail custom work while retaining its manufacturing roots. Family involvement has been central, with co-owners Vincent Keairns and Renne Keairns overseeing operations. Daughters Bilinda and Taylor contribute actively: Bilinda manages the storefront and marketing, while Taylor, a GIA-certified gemologist, focuses on CAD designs and production. Additional team members, including Mirza Bosnjak with his MatrixGold CAD/CAM Artisan certification, complement these efforts. The group's combined experience exceeds 100 years of master craftsmanship.
Addison Webster's GIA training aligns with the company's commitment to ongoing professional growth. It represents one phase toward potential advanced credentials, such as Graduate Diamonds or Graduate Gemologist. Her enhanced skills allow for more confident client guidance on diamond selection, ensuring designs reflect both creative vision and technical integrity. This development strengthens the overall custom process, from initial concept to finished piece, across various budgets and styles.
Client interactions at the company often involve collaborative design sessions that draw on the team's expanded knowledge. Past examples include restorations of family heirlooms and creations of unique items that incorporate personal elements. The in-house capabilities enable control over quality at every stage, informed by a wholesale background that supports fair and transparent practices.

Vincent Keairns, co-owner, reflected on the team's progress: "Addison's completion of the GIA Diamond Grading Lab course brings scientific depth to our design capabilities, allowing us to elevate every custom piece with informed precision."
Renne Keairns, co-owner, added: "This type of professional development across our staff reinforces the expertise we provide, ensuring clients receive jewelry grounded in both artistry and gemological knowledge."
