Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An oval cut lab grown diamond laid sideways across the finger and sunk into the face of a solid domed disc of metal, held by six sharp claws cut directly out of the dome so they read as the points of a star.
Two decisions make this ring what it is, and both are unusual. The first is orientation. Almost every oval engagement ring sets the stone north to south, running with the finger, because that lengthens the hand. Here the oval is turned ninety degrees and set east to west, so it lies across the finger. The stone immediately reads wider and flatter, the ring looks more like a signet or a seal than a conventional solitaire, and it sits lower and more securely against the hand. The second decision is the mount. Rather than a wire basket or a plain rub over bezel, the stone is set into the top of a solid domed cushion of metal, so there is a broad polished curve of gold or silver surrounding it on every side. The six claws are not applied on top of that dome. They are cut out of it, tapering to sharp points that run inward over the girdle, which is why from directly above the setting reads as a six pointed star with the diamond at its centre. The shank is a simple round wire that forks into two arms as it reaches the dome and joins it from beneath, leaving the dome apparently floating clear of the band.
A slim round wire shank, fully polished, that forks into two arms at the shoulders and meets the underside of the dome so the setting appears to float above the band. The interior is smooth and comfort rounded.
Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. White gold is shown in the photographs. Because the dome is a large uninterrupted polished surface, the metal colour matters more here than on a pierced or paved design.
The ring is made to your finger size. Select your size at checkout. If you are unsure, we will send you a printable size guide before we begin work.
We can change the carat weight, set the oval north to south in the same dome, brush or hammer the dome instead of polishing it, widen the shank, or add a hidden diamond under the dome. Write to us through https://mapplegems.com/pages/contact and our workshop will prepare a quotation and a rendering before any metal is cut.
Is a lab grown diamond a real diamond
Yes. It has the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same optical behaviour as a mined diamond, and it is graded on the same scales by the same laboratories.
Does the ring come with a certificate
Yes. An IGI certificate for the center stone is included at no extra charge.
What does east west setting mean
The oval is turned sideways so its long axis runs across the finger rather than along it. The stone reads wider, the ring sits lower, and the look is closer to a signet than a classic solitaire.
Does an east west oval look smaller
It looks wider rather than longer. The carat weight is identical, but a north to south oval lengthens the finger while an east west oval spans it, so the same stone gives a completely different impression.
Why are the claws shaped like star points
They are cut out of the dome itself rather than added on top, and tapered to sharp points running inward over the girdle. From above that reads as a six pointed star with the diamond at its centre.
Is this setting secure for daily wear
Very. Six claws in a solid metal dome protect the girdle on every side, and the low profile means the stone is far less exposed than in a raised basket.
Will the dome scratch
A large polished surface will pick up fine marks over years of wear, exactly as a signet ring does. Repolishing during servicing restores it, and it is included for life.
How long does the ring take to make
The dome is carved and the claws are cut from solid metal rather than assembled, so allow eighteen to twenty two working days before dispatch.
An east west setting shows the whole face of the oval flat to the eye, which means clarity and colour are visible in a way a raised north to south stone can disguise. Lab grown material lets us put an E colour VVS2 stone of two to five carats in that exposed position without the price a comparable mined stone would carry, with a traceable origin and no mining.
