Diamond Haus Custom Jewelers has announced that assistant manager and member of the custom design team Mirza Bosnjak has successfully completed the requirements to become a MatrixGold CAD/CAM Artisan. The certification, achieved in March 2026, enhances the company's capacity to deliver precise and innovative custom jewelry designs using advanced 3D software. This development reflects the ongoing investment in professional skills within the family-owned business, which has served clients since 1997.
Originally established as Fort Thomas Jewelers, the company began with a focus on jewelry repair and manufacturing for wholesale clients in local and national markets. It was later rebranded to Diamond Haus Custom Jewelers and expanded into retail services centered on custom design. The evolution has allowed greater collaboration with individual customers seeking personalized pieces. Family involvement remains central, with co-owners Vincent Keairns and Renne Keairns leading operations alongside their daughters Bilinda and Taylor, as well as additional team members like Mirza Bosnjak.
Bilinda manages the storefront and marketing efforts, while Taylor, a GIA-certified gemologist, specializes in hand-drawn custom CAD designs and related production tasks. The collective team's expertise exceeds 100 years, incorporating master craftsman skills in traditional hand-forging alongside contemporary tools. Mirza Bosnjak's new MatrixGold Artisan status adds depth to this foundation, particularly in the digital design phase of custom projects.
MatrixGold is an advanced 3D CAD and CAM software platform tailored for the jewelry industry. It supports parametric modeling, dynamic history tools, and photorealistic rendering, enabling designers to translate client concepts into detailed, production-ready files. The Artisan certification demonstrates proficiency in bridging creative ideas with manufacturing precision. For Diamond Haus Custom Jewelers, this means improved efficiency in design iterations, more realistic visualizations for client approval, and smoother transitions from initial sketches to final casting.
The custom jewelry process at the company follows defined steps that benefit from such technical advancements. Consultations allow staff to listen carefully to client needs and ideas. CAD designs, now further refined through MatrixGold capabilities, provide clear visualizations. Wax carving, casting, gem setting, and application of metal textures follow, culminating in delivery of the completed piece. This in-house workflow accommodates a range of budgets and styles, from engagement rings and bridal sets to necklaces, pendants, and heirloom restorations.
Mirza Bosnjak guides clients through the creation of unique jewelry that reflects personal stories, whether reimagining family heirlooms or developing entirely new designs. His certification supports faster and more accurate digital modeling, offering clients greater creative flexibility and confidence in the outcome. The achievement aligns with other recent team developments, including Taylor Benton's 2025-2026 AGS recertification and Addison Webster's completion of the GIA Diamond Grading Lab course.
Vincent Keairns, co-owner, stated: "Advancements like Mirza's MatrixGold Artisan certification allow our team to combine traditional craftsmanship with modern precision, ensuring custom pieces meet the highest standards of quality and detail."
Renne Keairns, co-owner, added: "Investing in our team's professional growth strengthens the expertise we bring to every client project and supports the continuation of our family business values."

Clients benefit from the integrated skills of the expanded team, which now includes enhanced digital design capabilities. The company continues to emphasize empathy and integrity in its approach, treating each commission as a meaningful contribution to clients' lives.
In addition to custom design, the business provides expert repair services, including work on challenging heirloom pieces. Bridal jewelry remains a core offering, with options for engagement rings and coordinating items. The team draws on wholesale experience to maintain fair practices informed by broad market knowledge.
Client experiences often highlight the collaborative nature of the design process. Many return for additional pieces or repairs, building relationships that span years. The integration of certifications across the staff reinforces the company's commitment to ethical standards and consumer trust in the jewelry sector.
