Guide

Metal, without mystique

We work in solid 18k gold and platinum 950. Every quote states the alloy, the gram weight and the finish — so you can compare like for like, here or anywhere else.

The alloys we use

Gold karats and platinum compared by purity, character and best use
MetalPurityCharacterBest for
9k gold37.5% goldHardest of the golds, palest colour; legal minimum for “gold” in the UK, not in all marketsBudget-conscious everyday pieces
14k gold58.5% goldThe US everyday standard; durable, slightly cooler colour than 18kEngagement rings worn daily
18k gold75% goldOur default. Rich colour, still bench-strong; yellow, rose and white (nickel-free) alloysMost commissions

About plating — the part others gloss over

Our default is solid metal, all the way through. Where plating or vermeil is requested (for example to match an existing piece), we say so explicitly on the quote and state a realistic durability expectation: plating is a surface, and surfaces wear. Gold vermeil over silver typically shows wear on rings within 1–3 years of daily wear; it can be re-plated, at a cost, more than once.

Plated pieces are never described as solid gold here — not on the page, not on the invoice. If you are comparing prices elsewhere and the number looks too good, ask what is underneath.

Skin contact: our white gold is nickel-free and platinum is naturally hypoallergenic. Tell us about sensitivities at inquiry stage and we will steer the alloy choice accordingly.

Commission

Begin with a sentence, a sketch, or a photograph.

Tell us what the piece should mean. We reply with a first direction, a price range and a timeline — free, and without obligation.
