About Bert Esterhuysen:
Master Business Administrator, Gemologist, Jewelry Professional, Senior Appraiser
Professional Experience
Bert brings a rare mix of bench-level gemology and real-world valuation savvy. Trained as a GIA Graduate Gemologist (and AJP), he’s spent years grading diamonds and colored stones, documenting findings clearly, and turning complex details into reports insurance companies, estate planners, and private clients can trust. His work emphasizes transparency—explaining what he sees, why it matters, and how it impacts value—so clients walk away confident, not confused.
Beyond the microscope, Bert helps jewelry businesses build better products and smoother operations. With his MBA, ASA appraisal background, AGS evaluation methods, and NAJA ethics at the core, he maps processes, tightens inventory workflows, and supports litigation needs when required. Whether it’s launching a collection or cleaning up a chaotic back office, his approach is practical, measurable, and designed to create clarity—and momentum—in both Pittsburgh and Ohio.
