Save 20%A two ring bridal set pairing an emerald cut lab grown diamond engagement ring with a channel set wedding band. Channel setting sinks the accent diamonds into a groove between two walls of metal, with no beads or claws holding them individually, so the band presents a flat continuous surface with the stones sitting flush inside it. That suits an emerald cut particularly well, because both the centre stone and the band are then built entirely from straight lines and level planes. It is also the most snag free way to set a wedding band, which matters on a ring worn every day. Every diamond is a laboratory grown diamond, identical in carbon structure, hardness and brilliance to a mined diamond, graded E colour and VVS2 clarity. Each set is made to order in our own Surat workshop and ships with a free IGI certificate for the centre stone.
Both rings are made to order in ten metal choices, so you can match the set to jewellery you already wear.
All gold options are solid gold, never plated or filled. White gold is finished with rhodium for a bright white surface and makes the channel almost disappear into the line of stones. Yellow and rose gold show the two metal walls clearly, which emphasises the architectural quality of a channel band.
Choose your ring size at checkout and both rings are made to that size. We make every size from US 3 to US 13, including half sizes, at no additional cost. If you are unsure of the size, order anyway and contact us after checkout, we will help you confirm it before the set goes into production.
Want the engagement ring on its own, pave instead of channel setting on the band, a plain wedding band, a hidden halo beneath the centre stone, a different centre shape, or engraving inside either shank, we can make it. For any other customization request please contact us at https://mapplegems.com/pages/contact and we will quote it for you.
Yes. The price shown is for the complete set, the engagement ring and the matching channel set wedding band together. Both are made in the metal and size you select.
Channel setting places the accent stones in a groove between two raised walls of metal, so each stone is held by the walls rather than by individual claws or beads. The surface stays flat and the stones sit flush, which means nothing protrudes to catch on clothing. It is the most durable way to set a row of diamonds in a band worn daily.
Yes. A lab grown diamond is real diamond. It has the same carbon crystal structure, the same hardness of 10 on the Mohs scale, the same refractive index and the same fire and brilliance as a mined diamond. The only difference is that it was grown in a controlled laboratory over a few weeks instead of underground over billions of years. No jeweller can tell the difference by eye, only specialist equipment reading growth patterns can separate the two.
Pave gives more surface sparkle because the stones sit higher and closer together with metal beads between them, but those beads can catch and wear. Channel setting gives a cleaner, flatter line with less brilliance but considerably more durability. For a wedding band that never comes off, channel is usually the better choice.
Step cuts have large open facets and no busy sparkle to distract the eye, so anything inside the stone is easier to see than it would be in a brilliant cut. That is why we set only VVS2 clarity in this design. At VVS2 any inclusions need 10x magnification to find, so the open facets stay clean.
Yes. Every set ships with a free IGI certificate for the centre stone. IGI is the International Gemological Institute, one of the largest independent diamond grading laboratories in the world. The certificate confirms the carat weight, the E colour grade, the VVS2 clarity grade and the laboratory grown origin. There is no extra charge for the certificate.
E colour is the second highest grade on the diamond colour scale and sits inside the colourless range, so the diamond looks bright white with no warm or yellow tint. VVS2 means very very slightly included, the second highest clarity tier. Any inclusions are so small that a trained grader needs 10x magnification to find them and they are completely invisible to the naked eye.
A lab grown diamond gives you a materially identical stone for a fraction of the price of a mined equivalent, and on a bridal set that saving applies twice over, across the centre stone and every diamond in the band. It matters especially on an emerald cut, which shows its size plainly with no scattered sparkle to disguise a smaller stone. Because the origin of every stone is documented from the moment it is grown, a lab grown diamond is conflict free by definition.
Mapple Gems is a made to order fine jewellery workshop based in Surat, India, the city that cuts and polishes the majority of the world's diamonds. We design and hand finish every lab grown diamond piece in house rather than reselling stock, which is why every ring on this store can be adjusted to the metal, carat weight and size you actually want. Our team works only with laboratory grown and certified stones, and every order is inspected and photographed before it leaves the workshop.
