My gemmological consultancy service provides academically grounded, ethical advice for private collectors and buyers seeking rigorous analysis and informed perspective in the study and acquisition of gemstones and diamonds. Rooted in gemmological science and material understanding, my service can support careful, evidence-based collecting with a focus on investment and development of high quality collections. As a Fellow of the Gemmological Association of Great Britain (FGA), I operate in full compliance with the Gem Code, the ethical code of conduct governing Gem-A members.

Advisory Support for Gemstone and Jewellery Acquisition and Collecting

Collecting gemstones and diamonds requires more than aesthetic appreciation; it demands critical evaluation of material quality, rarity, and context. I can provide advisory support to collectors and buyers by offering:

Detailed gemmological verbal assessment of gemstones and diamonds (if in person), with independent certification or valuations advised in any situation wherever you are, and general verbal assessments based on information provided from anywhere.

Pre purchase advise for any location, live general guidance and advice wherever you are provided reliable online connection.

Assessment of likelihood of natural origin, potential treatments, and material stability of gemstones, probable quality of jewellery, hallmark assessments based on information provided.

Consideration of rarity, comparative quality, and collector relevance.

Contextual expert guidance to support well-informed purchases and collection development

Advice can be provided independently and without involvement in sales, ensuring intellectual and professional objectivity.

Guidance on Independent Valuation

While I do not provide valuations directly (it would be unethical to claim independent valuations as I supply gemstones and jewellery), I recognise their vital importance for insurance, estate planning, and collection management. I can advise gemstone and jewellery owners on:

When and why an independent valuation is appropriate.

The most suitable valuation specialists or services for a specific piece.

The distinction between estate (probate), insurance replacement, open market value, capital gains valuations and reputable services for these.

I have no commercial relationships with any valuation services, I can assess any service you may be thinking of using, or recommend a well qualified, reputable and independent service suited to your specific needs.
This ensures valuations are obtained from appropriately qualified, impartial professionals and are aligned with the purpose required.

Care, Preservation, and Ownership

Material condition is fundamental to both the integrity and longevity of a collection.
I provide guidance on:

Storage environments and handling practices.

Cleaning and maintenance suited to specific gem materials of specific durability concerns, treatments, or inherent vulnerabilities.

Long-term preservation considerations for privately held collections.
