Product Description

1 Carat Princess Cut Lab-Grown Diamond Solitaire Engagement Ring in 14K Gold

A 1ct princess cut Lab-Grown Diamond, D–F color, VS+ clarity, IGI certified, held by four corner prongs on a plain polished band with a comfort-fit interior. Yellow, white or rose gold, cut to your finger and made in 7 to 10 business days on my bench in Woodside, Queens. Square, geometric, deliberately unadorned. Here is what people ask me before they buy a princess cut.

How big is a 1 carat princess cut?

About 5.5mm on each side — and corner to corner, roughly 7.8mm across the diagonal. That second number is the one that matters. Measured edge to edge a princess faces up smaller than a 1 carat round, which is about 6.5mm, because the square carries more of its weight in depth. But your eye reads the diagonal, and 7.8mm across the corners is wider than any round of the same weight. It looks bigger on the hand than the side measurement suggests.

Why is a princess cut cheaper than other shapes at the same carat?

Because of how it comes out of the rough. Diamond rough forms as an octahedron, and a princess cut is essentially half of one — two princess stones can be cut from a single piece with very little waste. A round brilliant throws away well over half the rough to get its shape. That efficiency is real and it shows up in the price, which is why this ring sits below the round and oval in the catalog for the same weight and the same grades. You are not paying less for a lesser stone.

What color and clarity is the diamond?

D through F, the colorless range, and VS+ clarity, which is eye-clean at any angle. Princess cuts are brilliant-faceted like a round, so they hide inclusions better than a step cut such as an emerald — but the corners can catch color, so staying in D–F keeps all four points as white as the center. The IGI report ships with the ring.

Why are the prongs on the corners?

The corners are the thinnest and most chip-prone part of a princess cut. Putting a prong on each one covers the vulnerable points and leaves all four faces of the stone open to light. It looks like the prongs are simply sitting at the widest points, but the placement is doing protective work — an exposed corner is the most common way a princess cut gets damaged.

Will a wedding band sit flush against it?

Not quite, and I would rather say so up front. The low cathedral lifts the stone slightly off the finger, which reads well on its own but can leave a small gap under a straight band. If you want them flush, tell me when you order and I will flatten the rise or contour the band to suit. Since both are made to order, this costs you nothing but the asking.

Is the gold solid, or plated?

Solid 14K throughout — not plated over brass, not gold-filled. White gold is rhodium-finished the way every white gold ring is, and I re-finish yours whenever it needs it. Nickel-free in all three colors, with platinum available.

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.

What if I want a thinner band or a different setting?

The same shape runs on a 1.5mm ultra-thin band at a smaller carat weight, in a full bezel, and with a hidden halo. For other shapes there is a 1ct round, a 1ct oval and a 1ct emerald cut.

Who makes it?

I do. One bench, one pair of hands, in a workshop in Woodside, Queens. Nothing here sits in a case waiting for a buyer — yours is cast, set and finished after you order it, cut to your finger rather than sized down to it. If something is wrong with it, you are talking to the person who made it.
