THREE WAYS TO WORK WITH US

From a brief to an informed choice.

01

Individual sourcing

We source to your specification, including beyond your initial catalogue shortlist. We discuss quality, origin and realistic alternatives within your budget.

02

Boutique and rare diamonds

For unusual colour, size or combinations of qualities, we review documentation, treatments and the available history of the stone. Each candidate is considered individually.

03

Specialist auctions

We can represent a client by individual instruction. The lot, maximum budget, fees and logistics are agreed in advance. An enquiry does not authorise bidding.

WHAT AN INVESTMENT DIAMOND MEANS

Rarity is a starting point. Analysis matters.

By “investment diamond” we mean a stone considered for long-term ownership or a collection. This is not a separate laboratory grade or a promise of returns. We discuss natural origin, quality, rarity, market comparisons and the total acquisition cost.

A grading report describes characteristics; it does not set a market price. Diamonds do not guarantee returns or a quick resale. Before a decision, we also consider delivery, insurance, fees and a potential future sale.
