Lab grown diamonds.

A lab grown diamond is a diamond. The same carbon, the same crystal, the same 10 on the Mohs scale. The difference is that it grew in a chamber instead of in the ground, so its origin is known and written down. Every stone we set arrives with its IGI or GIA report.

How they are grown

Every lab grown diamond starts as a thin slice of diamond called a seed. From there it is grown one of two ways. High pressure high temperature, or HPHT, puts the seed under the same crushing pressure and heat that forms a diamond underground. Chemical vapor deposition, or CVD, holds the seed in a chamber of carbon rich gas and builds the crystal up layer by layer. Both make the same material. What takes the earth a billion years takes a matter of weeks, and the result is a diamond by every measure a gemologist takes.

Grown, not mined

Because the stone is grown, we know exactly where it came from. There is no mine and no chain of hands between the ground and the setting. Growing a stone also uses far less land and water than mining one. Every stone comes with its IGI or GIA report, so none of this rests on our word.

One grade, every stone

Every lab grown diamond we set is E to F color and VVS2 clarity. We do not carry a lower grade at a lower price and leave you to work out the difference. There is one standard here, and it is at the top of the scale.

Six ready to order

Each one is a four prong solitaire in solid 10K, 14K or 18K gold. One carat starts at $2,550, and the ladder runs up through 1.5, 2, 2.5, 3, 3.5 and 4 carats. Choose the shape, the carat and the gold, and we make it to your size.

Every shape is also made with a hand laid pave band, with your choice of moissanite or lab grown diamond accent stones. See all twelve.

Diamonds in color

Lab grown diamonds are not only colorless. We source and set them in color, and a colored stone is priced above a colorless one of the same size. A green marquise lab diamond in 14K gold, for example, is $3,150.

Cuts you will not find in a shop window

Euro cut, antique cushion, Dutch marquise, moval and other period and modified shapes can all be cut to order. If you have seen a cut you want, send us the picture. We will tell you whether it can be done and what it will take.

Every ring includes

  • An E to F color, VVS2 clarity stone with its IGI or GIA report

  • Engraving inside the band, up to 20 characters

  • A ring sizer sent to you first, at no charge, if you are not sure of the size

  • Insured and tracked delivery

  • Made to order, hand set and hand polished, in 10 to 14 working days

If you want something else

Tell us below what you are picturing. The shape, roughly the size, the gold, and anything you have seen and liked. If you have not decided yet, say that too.

What happens next

We read it the same day and reply by email, usually within 24 hours, with the stones we can source and the report for each one.

You choose the stone. Nothing is charged until you have seen the certificate and agreed the piece.

We make US ring sizes 3 to 9, including half sizes. If you need a size outside that range, write to us before you order and we will arrange it.
