Emerald Cut Lab Grown Diamond Ring on a Split Double Rail Shank with Marquise Accents

Emerald Cut Lab Grown Diamond Ring on a Split Double Rail Shank with Marquise Accents

An emerald cut lab grown diamond held in corner claws above a shank that divides into two fine rails, each carrying marquise and round accents, running apart around the stone and rejoining beneath the finger. Between the rails is a narrow open window through which skin shows.

That window is the reason for the split. A solid shank places a continuous band of metal directly beside the centre stone, and metal is the thing the eye uses to judge how big the diamond is. Divide the shank and the metal beside the stone becomes two thin lines with a gap between them, so there is less of it to measure against and the diamond reads larger than the same stone on a solid band of the same total width. The gap does something else as well. On a solid shank the ring's outline against the finger is one continuous edge. On a split shank the skin visible through the window breaks that outline in two, and a broken outline is read by the eye as lighter, which is why a split shank ring looks delicate even when it carries more stones than the solid version. The two rails also give twice the surface for accents at no extra apparent bulk, which is what the marquises and rounds are doing here.

Center stone details

• Shape: emerald cut, step faceted
• Carat weight: 2, 3, 4 or 5 carat, selected at checkout
• Color grade: E
• Clarity grade: VVS2

Band details

The shank divides just below the shoulders into two fine rails that pass either side of the setting and rejoin under the finger. Both rails are the same width so the split reads as deliberate rather than as a taper, and the underside is a single band for comfort.

Metal options

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, where the matched tone lets the two rails read as one openwork shape rather than as two separate wires.

Ring size

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, and we set out the accents so both rails stay balanced at any size in our range.

Custom orders

We can change the carat weight, the centre stone shape, the width of the window between the rails or set only one rail. Write to us through https://mapplegems.com/pages/contact and our workshop will prepare a quotation and a rendering before any metal is cut.

Frequently asked questions

Is a lab grown diamond a real diamond
Yes. It is carbon in the same crystal structure as a mined diamond, with the same hardness and the same optical properties, 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.

Why does a split shank make the stone look bigger
Because there is less metal beside the diamond for the eye to measure it against, and the visible gap breaks the outline of the ring so the whole piece reads lighter.

Is a split shank strong
Yes. Two rails carry the load between them and rejoin into a single band under the finger, so the section that takes the most wear is solid.

Will a wedding band sit flush
The rails meet the setting at an angle, so a contoured band follows the line best. We can make one to match.

Can this ring be resized
Within a moderate range, working in the joined lower band.

How long does the ring take to make
Each ring is made to order. Production usually takes fourteen to eighteen working days before dispatch.

Why buy a lab grown diamond

A lab grown diamond gives you a larger stone and a higher colour and clarity grade for the same budget, with a traceable origin and no mining. An emerald cut shows its clarity plainly through the open table, so the grade is visible rather than theoretical.
