Introduction

Technical knowledge, practical insight, and independent judgement.

I am an independent jewellery and watch valuer with a strong technical foundation in gemmology, diamond grading, and valuation practice. My work is guided by precision, objectivity, and a deep respect for both the material and personal value of each piece.

My professional expertise is supported by advanced qualifications in diamond technology, gemmology, valuation, opal studies, cultured pearls, and laboratory-grown diamond assessment. These skills support a broad and technically informed understanding of natural diamonds, laboratory-grown diamonds, coloured gemstones, opals, pearls, and fine jewellery.

With additional experience in quality assurance within the jewellery and luxury sector, I bring a high level of consistency, detail, and professional judgement to every valuation. My approach combines technical knowledge with careful observation, clear methodology, and an understanding of both craftsmanship and market relevance.
