Lab grown diamonds

The same stone, a larger one

A lab-grown diamond is a diamond — same carbon lattice, same hardness, same fire. It is grown in a few weeks instead of a billion years, which is why the same budget buys a visibly bigger, cleaner stone. Every one we sell is certified and clearly described as lab-grown, on the site and on your invoice.

Looking for natural diamonds instead? We sell those too.

  • IGI / GIA certified

  • VS2 and above

  • Transparent stone pricing

  • 7-day easy returns

  • Bigger for the same money

    Roughly a fifth of the price of an equivalent mined stone. The budget that buys a 0.50ct natural solitaire buys well over a carat here, and the difference is visible from across a room.

  • Not a simulant

    This is not cubic zirconia or moissanite. It is crystallised carbon with the same structure, hardness and refractive index as a mined diamond, and it tests as diamond.

  • IGI certified

    Graded on the same 4Cs scale by the same laboratories, with the report number inscribed on the girdle and the stone identified as laboratory-grown.

  • Origin you can point to

    A known facility and a known date. No question of where it came from or whose hands it passed through on the way.

Laboratory-grown diamond. Physically, chemically and optically identical to a mined diamond. Certified by IGI, and described as lab-grown on your invoice.

How diamonds are graded

The four Cs, without the sales pitch

Every jeweller quotes these. Few explain which ones actually change what you see — and which ones you're paying for without noticing.

01

Cut

The one that decides sparkle

Cut isn't the shape — it's how precisely the facets are angled. A well-cut stone returns light back to your eye; a poorly cut one leaks it out of the bottom, and looks dull however large it is. If you optimise for one C, make it this one.

Scale

  • Excellent
  • Very Good
  • Good
  • Fair

We stock Excellent and Very Good only.

02

Colour

Graded by how little there is

Diamonds are graded D (colourless) through Z (light yellow). The difference between adjacent grades is invisible to the naked eye — which is why buying at G–H rather than D gets you a stone that looks identical for meaningfully less.

Scale

  • D–F colourless
  • G–J near colourless
  • K–M faint

We set G–H in white metals, and up to J in yellow gold where the warmth hides it.

03

Clarity

Nature's fingerprints

Almost every natural diamond formed with tiny inclusions. Clarity grades how visible they are under 10× magnification. Anything VS2 or better is 'eye-clean' — you will not see an inclusion without a loupe.

Scale

  • FL–IF flawless
  • VVS1–VVS2
  • VS1–VS2
  • SI1–SI2

VS2 and above, so every stone is eye-clean.

04

Carat

Weight, not size

Carat measures weight, not diameter. A well-cut 0.90ct can look larger than a deep-cut 1.00ct, and costs noticeably less because prices jump at round numbers. Buying just under a milestone weight is the most reliable way to get more stone for your money.

Scale

  • 0.30ct
  • 0.50ct
  • 0.70ct
  • 1.00ct+

Every stone above 0.20ct ships with its own certificate.

Certification

A stone you can verify
without taking our word for it

Every diamond above 0.20ct comes with an independent report from IGI or GIA. The report number is laser-inscribed on the girdle of the stone itself — invisible to the eye, readable under magnification.

You can type that number into the IGI or GIA website and read the full grading report from the laboratory, not from us. That's the point of certification: it doesn't rely on trusting the seller.

How a diamond piece is priced

Four numbers, all of them shown

Most jewellers quote a single figure for a diamond piece, which makes it impossible to tell whether you're paying for the stone, the gold or the markup. We separate all four.

  1. 01

    Metal value

    Today's gold or platinum rate multiplied by the exact weight of the mount.

  2. 02

    Stone charges

    The certified diamond itself, priced on its own 4Cs and shown as a separate line.

  3. 03

    Making charge

    A stated percentage of the metal value for the craftsmanship. Never hidden.

  4. 04

    GST

    3%, calculated on the subtotal and shown separately.

You'll see this breakup on every product page, before you add anything to your bag.

Questions worth asking any jeweller

They are the same material: identical carbon structure, identical hardness, identical sparkle. No one will look at your hand and tell the difference, and neither will a jeweller without specialist equipment. What differs is scarcity and price. A natural diamond formed over billions of years and the supply is finite, so it holds resale value. A lab-grown diamond was grown in a few weeks and can be grown again, which makes it roughly a fifth of the price — but prices have fallen year on year, so treat it as something to wear rather than an asset. Buying a milestone piece you may pass on: natural. Wanting the largest, cleanest stone your budget allows: lab-grown, comfortably. We sell both and we will not push you toward the expensive one.
Yes, and this is settled rather than a marketing claim. It has the same crystal structure, the same 10 on the Mohs scale, the same refractive index and the same fire. A standard diamond tester reads it as diamond. The only way to tell it apart is specialist equipment that detects the growth pattern, which is exactly how the certifying laboratory identifies it. It is not a simulant, and we would not call it a diamond if it were.
Almost certainly, and you should buy knowing that. Lab-grown production capacity keeps rising and prices have fallen substantially year after year. Resale value today is close to nil and there is no reason to expect that to reverse. Buy it to wear and enjoy, not as something to sell on. If value retention is part of why you are buying, choose natural instead — we would rather tell you that now than have you find out in ten years.
Every stone above 0.20ct carries an IGI or GIA report number, laser-inscribed on the girdle of the diamond itself. You can enter that number on the IGI or GIA website and read the full report independently of us. If any jeweller cannot give you a report number to verify, walk away.
Two reasons. We show the metal value, making charge, stone charges and GST separately instead of quoting one number, so you can see exactly what you are paying for. And we run one workshop rather than a chain of showrooms, which is why our making charges start at 10% rather than 20–25%.
You have 7 days from delivery for a full refund — no questions, no restocking fee. We do not offer exchanges, so if you are torn between two pieces, buy the one you prefer and return it rather than trying to swap later. Keep the invoice and certificate either way; together they establish the stone's identity and value if you ever sell it elsewhere.
