Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A radiant cut lab grown diamond on a band set with two kinds of accent stone: round brilliants and small emerald cuts. This pairing is unusual and it is the reason to buy this ring rather than a conventional pave design. A round brilliant scatters light into fine sparkle; an emerald cut is a step cut and returns broad flat flashes instead. Setting both along one band gives you two different kinds of light beside each other, and it echoes the centre stone honestly, because a radiant is itself a hybrid, cut with brilliant faceting inside a rectangular step cut outline. E colour, VVS2 clarity throughout, free IGI certificate for the centre diamond. Made to order in Surat in ten metals and four carat weights.
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. Because two accent shapes are used, metal contrast decides how clearly you read the difference between them. Yellow and rose gold outline each accent and make the mix obvious. White gold blends them into a single run of light and the design reads quieter. For everyday wear 14K is harder than 18K and holds small step cut accents level for longer.
Every ring is made to your finger size, so choose your size at checkout. If you are unsure, measure the inside diameter of a ring you already wear or ask us for a free size guide before ordering.
We can use only rounds, only emerald cuts, change the spacing, add a hidden halo, or carry the accents all the way round. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it before you order.
Why mix round and emerald cut accents?
Because they behave differently in light. Rounds give fine scattered sparkle, emerald cuts give broad flashes. Together they create contrast along the band instead of a uniform glitter. If you prefer one consistent effect, our plain pave radiant listings are the simpler choice.
What is a radiant cut?
A hybrid. It has the rectangular outline and cropped corners of an emerald cut but brilliant faceting inside, so it sparkles like a round while keeping a rectangular shape. It is the most brilliant of the rectangular cuts.
Are small emerald cut accents fragile?
They have straight edges and corners rather than a curve, so they must be set level and with the corners covered. Set properly they are no more vulnerable than any other accent, and the lifetime setting check covers them.
Does the carat apply to the accents?
No, the carat you select is the centre stone. The accents stay proportionate to the design.
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.
How long does it take to make?
Production usually takes ten to fourteen working days, plus shipping time to your address.
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 large certified centre plus two sets of shaped accents affordable in one ring. It is created without mining, so there is no excavation and no doubt about origin.
