Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A two piece bridal set. The engagement ring is an elongated radiant cut lab grown diamond in four claws over a hidden halo, on a fine plain band. The wedding band that sits with it is set all the way round with radiant cut lab grown diamonds, each one claw set and squared off so the band reads as a continuous line of rectangles rather than a row of dots. Matching the accent stones to the centre is what makes this set work. Most bridal sets pair a fancy shape engagement ring with a round brilliant eternity band, and the two shapes argue with each other. Here the band repeats the centre stone's outline at a smaller scale, so worn together the set reads as one continuous design rather than two rings sharing a finger. Both rings are included in the price. Free IGI certificate for the centre stone. Made to order in Surat in ten metals and four carat weights.
Two rings. The engagement ring with the certified radiant cut centre stone, and the matching radiant cut eternity band. Both are made in the same metal and to the same finger size, and both are included in the price shown.
Radiant cut lab grown diamonds run the full circumference of the band, each held in its own set of claws with the stones sitting edge to edge so almost no metal shows between them. The profile is kept flat so the band sits flush against the engagement ring without rocking.
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. Both rings are made in the metal you choose. White gold, as photographed, keeps everything colourless so the two rings read as one piece. Yellow and rose gold outline each stone more visibly and give a warmer look.
Both rings are made to your finger size, so choose your size at checkout. Please order carefully. A full eternity band cannot be resized without rebuilding it, because stones run the entire way around. Ask us for a free size guide if you are unsure.
We can supply the engagement ring alone, make the wedding band a half eternity so it can be resized later, change the centre to oval, emerald or cushion, or set the two rings in different metals. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it before you order.
Are both rings included?
Yes. The price shown covers the engagement ring and the matching eternity band together, in the metal and carat weight you select.
Why match the band stones to the centre shape?
Because shapes repeat better than they contrast. A radiant cut eternity band beside a radiant cut centre continues the same rectangular geometry down the finger. A round brilliant band beside a radiant centre creates two competing outlines that never quite settle.
What is a hidden halo?
A row of small diamonds set into the basket beneath the centre stone, facing outward instead of upward. Invisible from the front, but it lights the profile and lifts the head just enough to clear the wedding band.
Can the eternity band be resized?
Not easily, because diamonds run the full way around and there is no plain metal to cut into. If you expect your size to change, ask us for a half eternity version instead, which resizes normally.
Does the band sit flush against the engagement ring?
Yes. The engagement shank is straight rather than curved and the band profile is flat, so the two meet cleanly along their whole contact edge.
Do I get a certificate?
Yes. A free IGI certificate for the centre stone comes with every order, listing colour, clarity, cut and carat weight.
What is an elongated radiant cut?
A rectangle with cut corners and a brilliant faceting pattern beneath, so it has the clean outline of an emerald cut but the fire of a round. Cut longer than it is wide, it flatters the finger and looks larger for its weight.
A lab grown diamond is chemically and optically the same as a mined one, graded on the same scales by the same laboratories, at a fraction of the price. That gap matters most on a set like this, where you are buying a large certified centre stone and a full eternity band of matched fancy cut diamonds at the same time. It is grown rather than excavated, so there is no mining involved and the origin is never in question.
