Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A marquise cut lab grown diamond held by six claws with V tips over both points, flanked by a tapered baguette on each side, on a slim shank set with fine pave. Three stones in a row, all of them elongated, so the ring reads as one long line drawn across the finger.
Putting a straight edged stone against a curved one is a problem the cutter has to solve before the setter can begin. A baguette has four flat sides. A marquise has two shallow curves meeting at points. Set them side by side as cut and they touch at a single spot with a visible wedge of daylight behind the contact, which on a large centre stone is impossible to ignore. The answer is to re-cut the inner end of each baguette to a shallow concave that follows the exact curve of the marquise at its girdle, so the two stones meet along a line rather than at a point. It is done stone by stone against the individual centre diamond, which is why side stones for a design like this cannot be bought ready made. Once the join closes, the eye stops seeing three separate stones and starts reading the group as one continuous shape, which is the entire reason for choosing baguettes over rounds here.
The shank is slim and pave set through its upper half, stepping up at the shoulders to carry the baguettes. The lower half is plain, which keeps the ring comfortable and leaves clean metal for resizing.
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, which keeps the eye on the long silhouette of the three stones rather than on the metal that carries them.
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 adjust the pave run so the coverage looks even at any size in our range.
We can change the carat weight, the length to width ratio of the marquise, the size of the baguettes or remove the pave for a plain band. 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 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 are the side stones cut to fit
Because a straight baguette against a curved marquise meets at one point and leaves a visible gap. Shaping the inner end to the curve closes the join so the three stones read as one shape.
Are the marquise points protected
Yes. Both points sit inside V shaped claws that wrap the two facets meeting at each tip rather than gripping from one side.
Does a marquise look larger than other shapes
Yes. For a given carat weight it has one of the largest face up areas of any cut, because the weight is spread into a long shallow outline.
Can this ring be resized
Yes, working in the plain lower shank.
How long does the ring take to make
Each ring is made to order. The baguettes are cut to the individual centre stone, so production usually takes fourteen to eighteen working days before dispatch.
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. Since the baguettes here have to be cut specially anyway, growing them to match the centre in colour costs nothing extra.
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.
