Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%A cushion cut lab grown diamond held in four claws, flanked by one tapered baguette on each side. The baguettes are step cut, so instead of scattering light the way a brilliant does, they show long flat flashes that lead the eye inward to the centre stone. This is the classic mid century three stone arrangement, and it remains the most flattering way to make a cushion look wider without adding a halo. The band itself is left plain so the three stones carry the whole design.
The shank is plain, gently squared and polished, widening slightly where it meets the baguettes so the three stones sit in one straight unbroken line across the finger. There are no pave stones on the band.
Choose 925 sterling silver with rhodium plating, or solid 10K, 14K or 18K gold in yellow, rose or white. White gold, rhodium finished, gives the cool platinum style look shown in the photographs and is the traditional choice for a baguette three stone. Yellow gold gives a warmer art deco reading. Rose gold is the softest of the three. Every metal is hallmarked and every carat weight is available in every metal.
This ring is made to order in your size. Select your size at checkout. If you are unsure of your size, order in the size you usually wear and contact us, we will help you confirm it before the ring is cut.
We can use trapezoid or half moon side stones instead of baguettes, add pave to the band, remove the side stones for a plain solitaire, or set a different centre stone shape and carat weight. Send us your idea through https://mapplegems.com/pages/contact and we will send back a quote and a rendering before any metal is cut.
Is the centre stone a real diamond
Yes. A lab grown diamond is chemically, physically and optically identical to a mined diamond and is graded on the same scale by the same laboratories.
Does the ring come with a certificate
Yes. An IGI certificate for the centre stone is included at no extra cost with every order.
What is a tapered baguette
It is a rectangular step cut stone that is wider at one end than the other. Set with the wide end against the centre stone, it visually pushes the eye towards the middle and makes the shoulders look slimmer.
Do baguettes sparkle less than round diamonds
They sparkle differently. Step cuts show broad mirror like flashes rather than fine scintillation. Used as side stones this is deliberate, because it keeps the attention on the centre stone.
Are the side stones included in the carat weight shown
No. The carat weight you select refers to the centre stone. The two baguettes are supplied in a proportion matched to the centre stone size.
Can I wear a wedding band beside it
Yes, though because the baguettes sit low and flat, a straight band sits very close. We can also make a matching band to order.
How long does it take to make
Made to order rings usually leave our workshop within 10 to 14 working days. We confirm the date by email once your size is set.
A lab grown diamond is grown from a diamond seed under the same heat and pressure conditions that create diamonds in the earth. It has the same hardness of 10 on the Mohs scale, the same refractive index and the same fire. What changes is the origin, the traceability and the price. For the same budget you can buy a considerably larger stone with a higher colour and clarity grade, and you know exactly where it came from.
Mapple Gems is a jewellery workshop in Surat, India, the city where a large share of the world diamonds are cut and polished. We cut, set and finish every ring in our own workshop, which is why we can offer custom work at production prices. Every piece is inspected by hand before it is packed.
