Edward Boehm: Gemmologist, Dealer, and Trade Advocate
Co-founder of Rare Source and past president of the American Gem Trade Association
Edward Boehm — known throughout the coloured-stone trade as Eddie Boehm — is an American gemmologist and fine gemstone dealer whose career spans the intersection of rigorous gemmological practice and high-level commercial expertise. He is best known as co-founder of Rare Source, a consultancy and trading firm focused on exceptional coloured gemstones, and as a past president of the American Gem Trade Association (AGTA), the principal professional body representing the coloured-gemstone and cultured-pearl industry in the United States. His standing in the trade rests on a combination of deep species knowledge — particularly in ruby, sapphire, and other high-value corundum — and a sustained commitment to ethical sourcing and industry education.
Career and Rare Source
Boehm co-founded Rare Source as a vehicle for sourcing, evaluating, and trading gemstones at the upper end of the quality spectrum. The firm's name reflects its operating philosophy: a concentration on stones that are genuinely scarce by reason of colour, clarity, provenance, or size, rather than the broader commercial inventory that characterises most wholesale operations. This positioning requires a practitioner capable of navigating both the gemmological laboratory reports that underpin high-value transactions and the producing-country supply chains — from Mogok to Madagascar — where exceptional material originates.
Boehm's expertise is particularly associated with corundum. Ruby and sapphire occupy the most contested and technically demanding corner of the coloured-stone market, where distinctions of geographic origin, heat-treatment status, and filler detection can move a stone's value by multiples. Dealers operating at this level must be conversant with the methodologies of the major gemmological laboratories — including GIA, Gübelin, and SSEF — and capable of interpreting, and occasionally challenging, their findings in dialogue with clients and auction specialists.
Role at the American Gem Trade Association
The AGTA is the principal trade organisation for coloured-gemstone professionals in North America, with a membership that encompasses dealers, cutters, designers, and allied industry participants. As a past president, Boehm occupied the association's highest elected office, a position that carries responsibility for strategic direction, public representation of the trade, and liaison with regulatory bodies, laboratories, and international counterparts.
His tenure and broader involvement with AGTA have been associated with two areas of particular emphasis: trade education and ethical sourcing. The AGTA has long maintained a Source Watch programme and related initiatives designed to encourage transparency in supply chains, and Boehm has been a consistent advocate for the kind of provenance documentation and responsible sourcing practices that have become increasingly important to institutional buyers, auction houses, and end consumers alike. His participation in AGTA's Gemological Testing Center activities further reflects the organisation's effort to bridge commercial practice and laboratory science.
Conference Speaking and Industry Education
Boehm has been a frequent speaker at industry conferences, including events organised by AGTA and allied bodies. His presentations have addressed topics ranging from the practical evaluation of fine corundum to the evolving landscape of treatment disclosure and laboratory certification. This public-facing educational role is characteristic of a cohort of senior American coloured-stone specialists who have worked to raise the technical literacy of the broader trade — an effort that benefits buyers, designers, and ultimately consumers navigating a market in which treatment status and geographic origin carry significant commercial and ethical weight.
Speaking engagements at trade events such as the AGTA GemFair Tucson — the largest coloured-gemstone trade show in North America — place practitioners like Boehm in direct contact with the full breadth of the industry, from emerging dealers to established auction-house specialists, and provide a platform for the kind of nuanced discussion that written guidelines alone cannot convey.
Significance in the Coloured-Stone Trade
The figure of the gemmologist-dealer — a practitioner who combines laboratory-grade evaluative skill with the commercial acumen to source, price, and place exceptional stones — occupies a distinctive and important niche in the fine gemstone world. Such individuals serve as trusted intermediaries between producing regions, cutting centres, and the collectors, designers, and institutions that ultimately acquire significant material. Their credibility depends on a reputation for accuracy and integrity that, once established, is carefully maintained over decades.
Boehm's career exemplifies this model. His association with AGTA lends institutional weight to his standing, while Rare Source provides the commercial framework through which his expertise is applied in practice. In a trade where the line between scientific assessment and market judgement is frequently blurred, practitioners who can operate with authority on both sides of that line are genuinely scarce — a quality that, in its own way, mirrors the material they specialise in.
