A square cushion cut lab grown diamond held in four claws on a plain flat band. There is no halo, no hidden halo, no pave and no accent stone anywhere on this ring. It is the cushion cut presented on its own, which is the point. A cushion has the softened corners and rounded sides of an antique cut with modern brilliant faceting underneath, so it throws broad rounded flashes rather than the fine pinpoint sparkle of a round brilliant, and that character is easiest to read when nothing else is competing for attention. The band is flat across the outside rather than rounded, which gives the ring a crisp modern line and lets it sit tight against a wedding band. E colour, VVS2 clarity, free IGI certificate. Made to order in Surat in ten metals and four carat weights.
A plain band with a flat outer face and comfortable rounded inner edge, even in width the whole way round with no stones, engraving or milgrain.
Available in 925 sterling silver, 10K yellow gold, 10K rose gold, 10K white gold, 14K yellow gold, 14K rose gold, 14K white gold, 18K yellow gold, 18K rose gold and 18K white gold. On a design with no accent stones the metal is the entire setting, so the colour decision matters. Yellow and rose gold warm the stone and suit the antique character of a cushion. White gold and sterling silver keep it cool and modern and make the diamond look whiter still.
Every ring is made to your finger size, so choose your size at checkout. A plain band with no set stones is the simplest of all designs to resize later. Ask us for a free size guide if you are unsure.
We can add a hidden halo beneath the cushion, add pave to the shoulders, use double claws at each corner, or switch to an elongated cushion outline. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it before you order.
What is a cushion cut?
A square or slightly rectangular outline with rounded corners and curved sides, like a pillow. It combines the softened shape of an antique cut with modern brilliant faceting, which is why it gives broad rounded flashes rather than fine sparkle.
Is this cushion square or elongated?
Square. The length and width are close to equal, giving a compact chunky look. We also make elongated cushions, which are noticeably longer than they are wide.
Does this ring have any hidden detail?
No. The basket is plain and the band carries no stones. This is deliberately the most pared back version of a cushion solitaire we make.
Why a flat band instead of a rounded one?
A flat outer face gives a sharper more contemporary line and sits flush against a flat wedding band with no gap. A rounded band feels softer and more traditional. Both are available.
Are four claws enough for a large stone?
Yes, on a cushion. The claws sit over the four rounded corners, which are the strongest points of the outline, and hold securely even at 5 carats.
Is a lab grown diamond a real diamond?
Yes. Same carbon structure, hardness and brilliance as a mined diamond. Only the origin differs.
Do I get a certificate?
Yes. A free IGI certificate for the centre stone comes with every order, listing colour, clarity, cut grade and carat weight.
A lab grown diamond gives the same hardness, brilliance and fire as a mined stone at a fraction of the price, which is what makes a certified 4 or 5 carat cushion cut achievable. It is created without mining, so there is no excavation and no doubt about origin.
