Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An emerald cut lab grown diamond flanked by two smaller emerald cuts, all three held in full bezels that follow the cut corners of each stone, on a slim polished band.
Using the same cut for all three stones is what makes this design read as one deliberate object. The side stones repeat the proportions of the center diamond exactly, so instead of a big stone with accents you get a graduated row of three step cuts, and the eye moves along the line rather than stopping in the middle.
Bezel setting each stone rather than using claws is the second decision that holds it together. Every bezel is a continuous wall of metal cut to the octagonal outline of the diamond inside it, and because the three frames sit at the same height the whole head reads as a single machined block. It is a very art deco way of building a three stone ring, and it also protects the corners of all three step cuts, which are the parts most likely to chip.
The band stays quiet, slim and polished, meeting the outer bezels cleanly on each side.
A slim rounded shank, polished throughout, with no stones on the band. The three bezels sit low, so the ring has an even, flat top profile that slides under a cuff easily.
Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. White gold is finished with rhodium for a bright cool white, which is how this design is photographed. Yellow gold gives each bezel a strong warm outline and makes the three stone rhythm more graphic.
Every ring is made to order in your size. Select your size at checkout. If you are not sure of your size, order anyway and contact us, and we will help you confirm it before the ring goes into production.
We can change the center carat weight, the color and clarity grade, enlarge the side stones, or set them in a coloured gemstone. Write to us at https://mapplegems.com/pages/contact and we will quote your version.
Is the center stone a real diamond
Yes. A lab grown diamond is real diamond. 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. The only difference is where it was grown.
Does the ring come with a certificate
Yes. An IGI certificate for the center stone is included at no extra charge.
Is anything else in the photographs included
No. The lifestyle photographs show the ring worn on the hand for scale. You receive the ring only, in the metal, carat and size you select.
Why bezel set all three stones
Because it protects the corners of every step cut and gives the head a single continuous outline. Claws would break the line between the three stones and leave the corners exposed.
Can this ring be resized later
Yes. The band carries no stones, so sizing is straightforward in either direction. Your first resizing with us is free.
How is this different from your other emerald cut three stone ring
Our other emerald cut three stone design holds all three stones in claws with an open gallery. This one bezels each stone in metal, which is the more protective and more architectural of the two.
Does a wedding band sit flush against it
Yes. The bezels sit low and level and the band is straight, so a plain or eternity band sits neatly beside it.
How do I clean it
Warm water, mild soap and a soft brush. Bezel settings keep dirt out from under the stones better than claws, so this design stays bright with very little effort.
Which metal should I choose
White gold or sterling silver for a cool continuous look. Yellow or rose gold if you want each bezel outlined and the three stone rhythm emphasised.
A lab grown diamond gives you the same material as a mined stone with a documented origin. It also makes matched emerald cut side stones straightforward to source in the same colour and clarity as the center, which is difficult and expensive in mined goods.
