Every 24 KARAT piece is made once, for one client. We'll design something in the same spirit, made around you, in the gold and diamond you choose.

01 · The diamond

Lab-grown
or mined.

Grown in controlled conditions rather than mined. Physically, chemically and optically the same as a mined diamond, often letting you choose a larger stone for the same budget. A gemmological laboratory can tell the two apart, and every lab-grown report says so.

02 · The price

No retail
markup.

A ring from a traditional jeweller pays for the showroom, the display stock and layers of markup. We have none of that. You pay for the gold, the diamond and the design.

own ring.

It's the one you imagined. Design an engagement ring or a wedding band, with diamonds or in plain gold, and watch it come together in 3D. We'll refine every detail with you and send a personal quote.

Your design

How it works

Four steps. You approve the design before anything is made.

  1. Step 01

    Share your idea

    Send us your style, inspiration photos, preferred diamond and anything else you have in mind. A rough idea is enough.

  2. Step 02

    See your design

    We prepare a detailed design and a personal quote, so you see your piece before you commit. Ask for changes until every detail feels right.

  3. Step 03

    Approve it

    Once you're happy with the design and the price, you give the go-ahead. No surprises after approval.

  4. Step 04

    Receive your piece

    Your finished jewellery arrives ready to wear, with the grading report for its centre diamond.

The guide

Know your diamond

Everything worth knowing before you choose: shapes, the 4Cs, gold and settings. Ask us anything, there's no such thing as a silly question.

Round brilliant

The most sparkle of any shape, and the classic choice. The only shape with a full cut grade.

Oval

Elongated and flattering on the finger. Looks larger than a round of the same weight.

Cushion

A softened square with pillowy corners and a romantic, vintage feel. Also comes elongated.

Princess

Square with crisp corners and bright sparkle. Its corners are protected by V-shaped claws.

Emerald

A step cut with long, clean facets: less sparkle, more of a calm "hall of mirrors" glow.

Asscher

A square step cut with cropped corners and an Art Deco character.

Radiant

The clean outline of an emerald with the brilliance of a round. Durable cropped corners.

Pear

A teardrop that lengthens the finger. The point is held by a protective V-tip claw.

Marquise

A boat shape with two points. The largest-looking shape for its carat weight.

Questions, answered

Can't find what you need? Ask in your enquiry or send us a DM.

How long does a custom piece take?

It depends on the design. We'll give you a timeline with your quote, before you commit to anything. If you have a proposal, wedding or special date in mind, tell us in your enquiry and we'll plan around it.

How does payment work?

Every piece is quoted individually, so you'll know the full price before anything begins. Your quote sets out the payment terms, including any deposit, and nothing is made until you approve the design.

Why don't you show prices?

Because no two pieces are the same. The price depends on the design, the gold and the diamond you choose. Send us an enquiry and we'll prepare a quote for exactly what you want.

How do I find the right ring size?

If you know the size, add it to your enquiry; our size guide in the form converts Canadian/US, UK and millimetre sizes. If you don't know it, or you're planning a surprise proposal, tick "It's a surprise" and we'll walk you through simple, discreet ways to find it.

Do your diamonds come with a grading report?

Yes. Every centre diamond we supply comes with a GIA or IGI grading report. It records carat weight and quality, including colour and clarity grades on IGI reports, with a cut grade for round brilliants and polish and symmetry for other shapes. Lab-grown reports clearly state that the diamond is laboratory-grown. Small accent diamonds, such as pavé and halo stones, don't come with individual reports. Tell us if you prefer one laboratory over the other.

Lab-grown or mined: which should I choose?

Both are real diamonds with the same hardness and sparkle, and both come with independent grading reports. Lab-grown often lets you choose a larger stone for the same budget; mined appeals if natural origin matters to you. For lab-grown diamonds we usually recommend IGI, which gives full colour and clarity grades. Tell us your priorities and we'll show you both.

Can I check my diamond myself?

Yes. Every centre diamond we supply has a report number you can look up on GIA Report Check or IGI's verification, and most stones are laser-inscribed with it on the girdle. Ask us for the report number with your quote.

Is it real gold?

Always. We work in 10K, 14K, 18K, 22K and 24K gold. 24K is pure gold and comes only in yellow, and 22K in yellow or a soft rose. Both are very soft, so for claw-set and pavé diamonds we recommend 14K or 18K. White gold is usually finished with rhodium, which can be refreshed over time. Tell us the karat and colour you'd like and we'll advise on the best option for your design.

What kinds of jewellery do you make?

Rings, wedding bands, necklaces, bracelets, earrings and anything else you have in mind. If it's jewellery and you can describe it, we can quote it.

Do you make custom pieces for clients outside Toronto?

Yes. We work with clients across the GTA and throughout Canada. Delivery is arranged with your quote.

Find your size

Wrap a strip of paper round the base of the finger, mark where it meets and measure the length in millimetres. Or measure across the inside of a ring they already wear on that finger. A guide only: we'll confirm the size with you before anything is made.

No obligation. We'll reply with questions, ideas and your personal quote, and only use your details to do so.
