LAB GROWN CUSHION CUT DIAMONDS

A cushion is a square with its corners rounded off and its facets cut large. Fewer, broader facets means it throws color instead of the fine white sparkle of a round. It's the cut that looks warmest in low light. Browse all 9 pieces, rings and stud earrings, every one of them lab grown, in 14K or 18K white, yellow, or rose gold, or platinum, with prices ranging as low as $1,152.99

THE DETAILS

Buying a Lab Grown Cushion Cut

A short shelf, and a cut most people have seen without knowing its name. Here is what it actually does.

Its facets are bigger and there are fewer of them, so light comes back in broad flashes with visible color in them rather than in fine white points. People usually describe it as warmer, and you don't need a loupe to see it: candlelight is where the difference shows.

A ratio of 1.00 to 1.05 is the square cushion most people picture. Push past 1.10 and it reads as a rectangle and starts to lengthen the finger the way an oval does. Neither is more correct; they just look like different rings.

It's diamond. Same crystal, same hardness, graded on the same color and clarity scales, and it takes equipment to tell one from a mined stone. It costs a great deal less than a mined cushion of the same specification, which is why the floor on this shelf sits where it does.

No. Rounding the corners takes the weak spot off the stone before it reaches a setting, so a cushion doesn't need the corner prongs a princess takes or the V prong a pear takes. That makes it one of the easier shapes to wear every day.

Because that's the honest count of cushion cut designs we list ready to order, and padding the page with the same ring at three more weights wouldn't help you decide anything. Anything else in cushion is made to order, designed in 3D first, and that design work is free with no deposit.

About Our Lab Grown Cushion Cut Jewelry

The cushion descends from the old mine cut, the shape most Victorian diamonds were cut into before electric light changed what people wanted from a stone. That history is why a cushion reads antique even when the ring around it is brand new.

Browse all 9 pieces, all cushion cut, all made to order in our own US factory in 14K or 18K white, yellow or rose gold, or in platinum.

The diamonds run every one of them lab grown, and prices range as low as $1,152.99. It's a small shelf, and we'd rather it stayed accurate than looked full.

A cushion halo, a heavier center or a three stone in this cut is made to order. Send us the idea and our jewelers will design it in 3D before a stone is set. Whatever we build ships free inside the US, carries a Lifetime Limited Labor Warranty on the setting work, and comes back within 30 days of the ship date.
