Why Custom, Why Here

One-of-one custom wedding & engagement rings, from someone who'll still be here to fix it.

H&Z has assisted clients custom-designing engagement rings, wedding rings, and special-occasion pieces for many years — from a first sketch on paper to a finished ring on someone's hand. There's no rotating showroom floor and no sales quota: just our team, working through what you actually want, one appointment at a time.

That includes resets of inherited stones, redesigns of pieces you've outgrown, and full repairs or resizing on jewellery you already own — not just new builds.

How A Custom Piece Gets Made

Four Steps, No Guesswork.

Scroll to watch it come together
01The idea

Consultation & Sketch

Book a free, private appointment. Bring a reference photo, an inherited stone, or just an idea — our designer sketches concepts with you in the room.

02The materials

Stone & Metal Selection

Choose a lab-grown or mined diamond (IGI/GIA certified), coloured stone, or your own, in 14K white, yellow, or rose gold.

03The making

Hand-Built On-Site

Your piece is built and set in the Ancaster workshop — not shipped out to a third-party factory.

04The fit

Fitting & Lifetime Care

Final fitting, sizing, and finishing before pickup — plus resizing and repair whenever you need it, for as long as you own it. Purchases come with a lifetime warranty, excluding the centre stone.

The result

From a sketch on paper to a ring that’s entirely yours.

Every custom piece starts the same way — a conversation, a sketch, and the right stone. Bring your idea; we’ll take it from there.

Common Questions

Custom Jewellery, Answered

It depends entirely on the stone and design, but we can work with any budget starting from 0.50 carat. Bring your range to the consultation and we'll show you what's realistic within it — no pressure to go bigger.

Yes. We regularly reset inherited stones and redesign pieces clients already own into something they'll actually wear.

Timelines vary by design and stone sourcing — we'll give you a real estimate at your consultation rather than a generic number here. Custom jewellery requires a 50% deposit and normally takes two weeks.

Either — it's your choice. Both are independently certified by IGI or GIA. Lab-grown typically runs 50–70% less for a comparable stone.
