What the IGI certificate confirms

The International Gemological Institute is the leading grading lab for lab-grown diamonds. Its report independently confirms this diamond's carat weight, cut, colour, clarity, measurements and growth method. Enter LG745523227 on the IGI website to see the full report. This isn't a seller's claim. It's a document from an accredited laboratory.

What CVD means

Chemical vapour deposition is a premium method of growing diamonds. Carbon atoms are deposited layer by layer onto a diamond seed in the same crystal structure as a natural diamond. The result has the same hardness, refractive index and fire as a mined diamond. The only difference is where it was created, not what it is.

F colour at 10 carats

Diamond colour runs from D (colourless) to Z (visibly yellow). F is in the colourless range and looks the same as D or E to the naked eye. At 10 carats, F colour reads completely white and brilliant in every light, and it pairs beautifully with platinum, white gold or yellow gold.

VS1 clarity

Inclusions in a VS1 diamond can only be found under 10x magnification. To the eye, this stone is clean and brilliant from every normal viewing distance.

The radiant cut

The radiant cut combines the rectangular outline of an emerald cut with brilliant-style faceting, giving maximum fire and sparkle in a rectangular shape. At 14.54 × 10.97 mm face-up, this stone covers the width of a finger and reads as a statement from across a room.

Who this stone is for

Couples who want a statement engagement ring in a solitaire, three-stone or halo design. Buyers who want maximum presence on the finger. Ethical buyers who prefer to avoid mined diamonds entirely. And designers and goldsmiths creating a significant custom piece.

Size and setting reference

At 14.54 × 10.97 × 6.82 mm, this diamond needs a custom or semi-custom setting with enough basket depth to hold it securely. A skilled goldsmith can make a bezel, four-prong or eight-prong solitaire to fit. Full dimensional data is available on request, so please share it with your jeweler before choosing a setting.

A gemstone for him: the men's signet ring

At Roho Jewels, we believe men deserve beautiful gemstones too. A certified radiant cut lab-grown diamond set into a signet ring is a bold, personal alternative to a plain metal signet: one-of-a-kind, full of character, and a ring he'll wear for decades and one day pass down.

• Signet face: at 14.54 × 10.97 mm, this stone suits a signet face of about 18–21 mm (most men choose a face of about 15–18 mm), great on the ring or middle finger
• Setting: flush (gypsy), bezel or half-bezel keeps it low and smooth, with no claws to catch on sleeves or gloves
• Depth: the stone is 6.82 mm deep, so ask your jeweler for a signet head at least 7.8 mm deep
• Metal: rich in yellow gold, sharp in white gold or platinum, rugged in oxidised sterling silver
• Wear: Mohs 10, the hardest gemstone on earth, made for a ring worn every day
• Perfect for: husbands, fathers, grooms, graduates, milestone birthdays, or a signet he buys for himself

Common questions

Can I verify the certificate before buying? Yes. Enter LG745523227 on the IGI website to see the full report.

Is F colour noticeably different from D or E? Not to the naked eye. In a finished ring it reads as a perfectly white diamond.

Is it really identical to a mined diamond? Physically, chemically and optically, yes. Specialist lab equipment is needed to tell them apart, which is why the IGI report clearly states lab-grown.
