Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An elongated cushion cut lab grown diamond in four claws, with the band splitting into two arms as it approaches the head and two separate rows of pave hidden beneath the stone. The split shoulder is doing structural work, not just decoration. As the shank nears the head it divides, and the two arms rise to meet the basket from either side rather than a single thick post carrying the load. That spreads the weight of a large centre stone across a wider footprint, which matters at 4 or 5 carat, and it leaves an open window between the arms that light passes through. Inside that space sit two rows of pave, one wrapping the basket directly under the cushion and a second running along the bridge below it. From the front the ring is a clean solitaire. From the side it is a small piece of engineering. Free IGI certificate for the centre stone. Made to order in Surat in ten metals and four carat weights.
A polished band that divides into two arms as it rises toward the head, meeting the basket from either side and leaving an open space between them. Two rows of pave sit beneath the centre stone, one in the basket and one along the bridge below. The lower shank is plain and unbroken.
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. White gold, as photographed, makes the split arms read as a single clean structure. Yellow and rose gold separate the two arms visually so the split is more obvious.
Every ring is made to your finger size, so choose your size at checkout. The lower shank is plain and undivided, so resizing is straightforward. Ask us for a free size guide if you are unsure.
We can close the split into a single shank, drop back to one hidden halo, add pave to the shoulders, or change the centre to oval, radiant or emerald. 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 split shoulder?
The band divides into two arms before it reaches the head, so the stone is supported from both sides rather than by one central post. It spreads the load of a large stone and creates an open space beneath it.
What is a double hidden halo?
Two separate rows of small diamonds set beneath the centre stone. The upper row wraps the basket directly under the cushion, the lower row runs along the bridge between the split arms. Neither is visible from above.
Is a split shoulder stronger?
For a large centre stone, generally yes. Two arms distribute stress over a wider area of the shank than a single junction does, which reduces the chance of the head working loose over years of wear.
What is an elongated cushion cut?
A rectangle with rounded corners and a brilliant faceting pattern, sometimes called a pillow cut. Elongated means it is cut longer than wide, which flatters the finger and gives more spread than a square cushion of the same weight.
Does the open space collect dirt?
Less than a closed basket, in fact. An open gallery lets water and soap pass straight through when you clean it, which is easier than flushing a solid cup.
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.
Will a wedding band sit against it?
Yes. The lower shank is plain and straight, so a band meets it cleanly below where the split begins.
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 is what makes a VVS2 E colour elongated cushion at 4 or 5 carat achievable, and at that size the split shoulder construction earns its place. It is grown rather than excavated, so there is no mining involved and the origin is never in question.
