Real diamonds, grown instead of mined

A lab-grown diamond is a diamond: the same carbon crystal, the same hardness, the same fire, graded by the same laboratories on the same 4C scale as a mined stone. The only difference a gemologist can find is the growth environment, and finding even that requires specialized equipment. What you and everyone else will see on the hand is simply a diamond.

What lab growth changes is the economics. The same budget reaches two to four times the carat weight, or steps up several color and clarity grades, or both. A two-carat stone that would be out of reach mined becomes an ordinary Tuesday decision grown. That is why the majority of engagement ring centers we sell today are lab-grown.

Our collection runs deeper than the standard shapes. Alongside more than 800 rounds, ovals, pears and emerald cuts, we stock lab-grown antique cuts, old mine and old European style stones faceted to the hand-cut proportions of the 1800s, a combination of character and price that almost no other retailer offers.

How to choose well

Buy the certificate and the video together. Every stone here carries independent IGI or GIA grading, and every stone is filmed in 360° so you can judge what the grade cannot show: how it actually handles light. From one carat up, prioritize cut quality first, then color, then clarity, in most shapes VS2 and SI1 stones are indistinguishable by eye from flawless at a fraction of the price.

Prices on this page start around $1,000 for certified stones over a carat. Pair any stone with any Hitched setting and the full ring price shows before checkout, no surprises at the end.

Questions, answered

Are lab-grown diamonds real diamonds?

Yes. A lab-grown diamond is chemically, physically and optically identical to a mined diamond, pure crystallized carbon at 10 on the Mohs scale, graded by the same laboratories on the same color, clarity, cut and carat scale. Distinguishing one from a mined stone requires specialized laboratory equipment.

How much cheaper are lab-grown diamonds?

Typically 60 to 80 percent less than a comparable mined stone. In practice the same budget moves you up two to four times in carat weight or several grades in color and clarity. Our certified lab-grown inventory starts around $1,000 for stones over one carat, with two-carat stones commonly between $1,500 and $4,000.

Do lab-grown diamonds test as diamonds?

Yes. On a standard diamond tester a lab-grown stone reads as diamond, because it is one. Only advanced spectroscopy in a grading laboratory can identify the growth origin, and the result is printed on the certificate, which is why every stone we sell carries independent IGI or GIA grading.

Will a lab-grown diamond cloud, fade or change over time?

No. A lab-grown diamond is as permanent as a mined one, the same crystal with the same hardness and stability. It will not cloud, yellow or lose brilliance with age. Clean it the way you would any diamond and it will look identical in fifty years.

IGI vs GIA for lab-grown diamonds, does it matter?

Both are reputable independent laboratories. IGI grades the majority of the world’s lab-grown diamonds and its reports are the market standard for them; GIA grades fewer lab stones but carries the longest reputation in mined diamonds. We stock both and print the certificate on every stone’s card, judge the stone by its video either way.

Can I get an antique-cut lab-grown diamond?

Yes, and it is one of the rarest things we offer. We stock lab-grown old mine and old European style diamonds cut to the historical proportions: high crowns, small tables, open culets. The romance of an 1800s cut with a modern certificate and a lab-grown price, and each one is filmed in 360°.
