Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An emerald cut lab grown diamond turned sideways so its length runs across the finger rather than along it, set low in four claws on a flat yellow gold band with nothing else on the ring.
Turning a long stone east to west changes what the ring does to the hand. Set the conventional way, an emerald cut points along the finger and its length is read against the length of the finger, so the two compete and the stone tends to look narrow. Turned ninety degrees, the same stone spans the finger and the eye now reads its length against the finger's width, which is a much smaller measurement, so the diamond appears substantially wider than the identical stone set north to south. There is a practical consequence as well. An east west stone sits with its short axis running along the finger, so it clears the knuckle more easily and is less likely to catch when the hand closes, which is why the orientation was common in signet and gypsy set rings long before it returned as a modern choice.
The shank is flat rather than round, with square edges and an even width the whole way round. A flat band gives the stone a straight line to sit on, which suits the straight facet edges of a step cut in a way a curved wire does not.
Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. Yellow gold is shown in the photographs, where the flat polished surface reads as a clean bar across the finger.
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 stone north to south instead, use a bezel rather than claws, or add a concealed halo. 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, hardness and optical behaviour as a mined diamond and is graded on the same scales.
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 mean
The long axis of the stone runs across the finger rather than along it.
Does an east west setting make the stone look bigger
It looks wider, because its length is measured against the width of the finger rather than the length. The stone is the same size either way.
Is an east west ring comfortable to wear
Yes, often more so. The short axis runs along the finger, so the ring clears the knuckle easily and is less likely to catch.
Can this ring be resized
Yes. The band carries no stones, so resizing is done entirely in plain metal.
How long does the ring take to make
Each ring is made to order. Production usually takes twelve to sixteen working days before dispatch.
An emerald cut has large open facets that show colour and inclusions plainly, so grade matters more here than in a brilliant. A lab grown diamond makes an E colour VVS2 emerald cut of this size achievable, with a traceable origin and no mining.
Mapple Gems is a jewellery workshop in Surat, India, the city where a large share of the world's diamonds are cut and polished. We grow, cut, grade and set in one place, which is why we can offer certified stones in fully hallmarked gold at workshop prices.
