2 Carat Round Lab-Grown Diamond Solitaire Engagement Ring
A 2ct round brilliant Lab-Grown Diamond, D–F color, VS+ clarity, IGI certified, four-prong set on a plain polished band in solid 14K gold. Made to order in 7 to 10 business days on my bench in Woodside, Queens. Two carats in a round brilliant is the size people picture when they say large.
How big is a 2 carat round diamond?
About 8.1mm across. A 1ct round measures 6.5mm and a 1.5ct measures 7.4mm, so the steps get smaller as the weight climbs — that is geometry, not a trick. Doubling the weight from one carat adds only about 1.6mm to the diameter, because weight grows with volume while what you see is a flat circle. On a size 6 finger an 8.1mm round covers most of the width and there is no mistaking it for anything smaller.
Is 2ct worth the jump from 1.5ct?
It is the largest step in price of any upgrade in the catalog, and the smallest step in millimeters. Large rough is the scarcest thing in the diamond trade, and price per carat climbs steeply past a carat and a half. What you are buying at 2ct is not a proportionally bigger stone — it is the number itself, and the presence that comes with a stone that reads unambiguously large across a room. For some people that is exactly worth it. For others, a 2ct oval at 10mm long gets more visible size for the same money, and I will tell you so.
Why does cut matter most at this size?
Because a 2ct round has nowhere to hide. A poorly proportioned stone leaks light through the bottom instead of returning it, and the larger the stone the more obvious the dead center becomes. A well-cut 1.75ct will outshine a badly cut 2.25ct in any light, at any distance. Cut is the only one of the four Cs that is entirely workmanship rather than luck, and at two carats it is the difference between a stone that looks alive and one that looks like glass.
What color and clarity is the diamond?
D through F, the colorless range, and VS+ clarity, eye-clean at any angle. A round brilliant's faceting hides more than any other shape — both inclusions and warmth get broken up in the light return — but at 2ct there is simply more stone, and grades that pass at a carat start to show. The IGI report ships with the ring.
Which wedding band fits it?
A contoured band. There is a second gallery under the head — an extra rail of gold beneath the basket that carries the stone's weight and stops the prongs flexing over years of wear. It is why this head will still be tight in a decade, and most makers leave it out. It is also why a straight band will not seat: the band meets the gallery rather than the shank and stands off, leaving a gap under the stone. A curved band dips at the center, clears the gallery and nests flush. I make both to order, so tell me and I will cut the pair to meet properly — or start with the plain contour band or the pavé contour.
How long does it take, and can it be resized?
Made to order in 7 to 10 business days, sizes 4 through 9 including halves. Resizing is complimentary within 60 days of delivery, craftsmanship carries a lifetime warranty, and you have 14 days to return it if it is not right and you have not had it engraved. It ships fully insured in our signature suede pouch with the IGI report.
Want a different weight or shape?
The same ring runs at 1ct. To compare shapes at this weight, start with the diamond shape guide. Anything not on the site, I build custom — that is most of what I do.
Who makes it?
I do. One bench, one pair of hands, in a workshop in Woodside, Queens. A two carat head has to be built heavier than a one carat head or the prongs flex over time — that is the kind of decision that does not show in a photograph and shows in ten years. Nothing here sits in a case waiting for a buyer.
