A calm, clear guide to lab-grown diamonds, the 4Cs, diamond shapes, certification, and what truly matters when choosing a stone for a custom piece.

Choosing a diamond can feel complicated from the outside. Cut, colour, clarity, carat, certification, proportions, pricing it is a lot to take in.
Shape is where technical choice becomes personal. Each silhouette carries a different feeling, from timeless to architectural to softly modern

Classic, brilliant, timeless.

Oval
Elegant, elongated, softly modern.

Pear
Distinctive, graceful, expressive.

Emerald
Architectural, understated, refined.

Elongated Cushion
Distinctive, graceful, expressive.

Princess
Romantic, soft, dimensional.

Marquise
Distinctive, graceful, expressive.

Bold, bright, and structured.

Asscher
Bold, bright, and structured.
Understanding the 4Cs Cut, Colour, Clarity and Carat makes it easier to compare a diamond's appearance, quality and overall value with confidence.
Cut determines how effectively a diamond reflects and returns light. It is what creates the brightness, fire and sparkle you see when the stone moves. Even a diamond with exceptional colour and clarity can appear dull if its proportions compromise light performance. This is why we consider cut the most important of the four Cs.

Excelent
Brilliant, balanced, precise

Very Good
Bright, refined, impressive

Good
Pleasant, moderate, acceptable

Fair
Uneven, subdued, compromised

Poor
Dull, imbalanced, lifeless
We'll review the diamond certificate with you and explain what it all means, so you can understand the grading and make an informed decision without having to do all the homework yourself.
We'll review the diamond certificate with you and explain what it all means, so you can understand the grading and make an informed decision without having to do all the homework yourself.
It's not all about the paperwork. We personally hand pick and visually review every diamond because a certificate doesn't always tell the full story. Whether you're with us in person or online from anywhere in the world, we'll make sure your diamond truly sparkles.

Lab-grown diamonds are created in controlled environments rather than mined from the earth. They are chosen for beauty, value, and a more considered sourcing path.
Many clients choose lab-grown diamonds for value, allowing them to prioritise size, quality, or design within the same budget.
Certification, cut quality, proportions, and real light performance matter more than chasing the highest grade on paper.
Lab-grown diamonds offer the visual beauty people expect from fine jewellery, with a different origin story and a more transparent buying process.
Guidance on our process, craft, and commissions.
A commission unfolds over six to eight weeks, from the first appointment to the finished piece. The early weeks are given to selection and design; the remainder to the workshop, where the piece is set by hand. Timelines are shaped by the nature of the design and the stone, and we provide a considered estimate once the brief is settled. Where an occasion is fixed, tell us the date, and the house will work to meet it.
Yes. A lab grown diamond is diamond in every physical, chemical, and optical respect. It is graded to the same standards, certified by the same laboratories, and indistinguishable to the eye. The single distinction is origin: one is formed within the earth over millennia, the other grown under the same conditions in a matter of weeks. We work almost exclusively in lab grown stones because they allow a finer diamond for the same investment, with no compromise in quality.
Certainly, and it is among the most meaningful work we undertake. A number of our commissions begin with a stone already held: an inherited diamond, or a stone from a piece no longer worn. Before any design proceeds, the stone is examined closely for its condition, as older stones can carry inclusions or wear that affect how they may be reset. We will advise you honestly on what can be done, and on any precautions the setting requires, so that its history is carried safely into something made to be worn again. Sentiment is treated with the same care as the metal.
We do. Much of the consultation can happen remotely, with secure shipping and full certification for clients outside Melbourne.
Gentle regular cleaning and periodic professional checks keep it brilliant. We include care guidance with every piece.
