Technical Skills
While inspecting a batch of loose diamonds for a high‑end retailer, I noticed an unusually low refractive index in one stone.
I needed to verify authenticity, prevent a costly mistake, and maintain client trust.
I used a handheld spectroscope, consulted the GIA database, and isolated the stone. I reported findings to the purchasing manager, recommended returning the stone, and documented the incident in our quality log.
The counterfeit was removed before shipment, saving the client $12,000 and reinforcing our reputation for rigorous quality control.

Working at a boutique studio, clients increasingly requested contemporary, minimalist pieces.
I needed to integrate fresh design trends while preserving the brand’s classic aesthetic.
I subscribe to industry publications (JCK, National Jeweler), attend the annual JCK Show, follow leading designers on Instagram, and experiment with CAD software to prototype trending motifs.
Within three months, I introduced a new line that boosted sales by 15% and received positive press in a local design blog.

Customer Service & Sales
A client commissioned a bespoke heirloom necklace incorporating a family crest, rare sapphire, and 18k rose gold, with a tight six‑week deadline.
Deliver a flawless, emotionally resonant piece on time while managing client expectations.
I conducted an initial design workshop to capture the story, created detailed sketches, produced a 3D CAD model for client approval, sourced the sapphire from a certified dealer, and coordinated with a trusted goldsmith for casting. I provided weekly progress updates and addressed concerns promptly.
The necklace was completed two days early, the client praised the craftsmanship, and referred three new high‑value clients, generating an additional $25,000 in sales.

Our studio launched a 20‑piece sterling silver collection with tight tolerances for finish and durability.
Implement a systematic QC process to catch defects before shipping.
I established a three‑stage inspection: (1) visual and dimensional check after casting, (2) ultrasonic testing for internal cracks, (3) final polish and wear test. I created a checklist and trained the team on documentation, and set up a defect‑tracking spreadsheet to identify recurring issues.
Defect rate dropped from 8% to 1.2% within the first month, reducing rework costs by $3,500 and improving on‑time delivery to 98%.
