Radiant Cut Lab Grown Diamond Solitaire Engagement Ring with Wide 3MM Band, E Color VVS2

Radiant Cut Lab Grown Diamond Solitaire Engagement Ring with Wide 3MM Band, E Color VVS2

A radiant cut lab grown diamond set alone on a wide flat 3mm band. Most solitaires are built on a fine shank that disappears under the stone, and this one deliberately does the opposite, the band has real presence on the finger and gives the ring a solid, architectural weight. Against that width the radiant reads as grounded rather than perched, and the flat surface catches light along its whole length. It is a quieter, more modern look than a thin band, and it suits people who want the ring to feel substantial without adding a single accent stone. 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 ring is made to order in our own Surat workshop and ships with a free IGI certificate for the centre stone.

Metal options

This ring is made to order in ten metal choices, so you can match it to jewellery you already wear.

• 925 Sterling Silver
• 10K Yellow Gold, 10K Rose Gold, 10K White Gold
• 14K Yellow Gold, 14K Rose Gold, 14K White Gold
• 18K Yellow Gold, 18K Rose Gold, 18K White Gold

All gold options are solid gold, never plated or filled. White gold is finished with rhodium for a bright white surface. Yellow gold is the metal shown in the photographs, and a wide band shows far more metal than a thin one, so the colour you choose matters more on this design than on most.

Ring size

Choose your ring size at checkout. We make every size from US 3 to US 13, including half sizes, at no additional cost. A wider band sits closer on the finger than a thin one, so some people prefer to go up a quarter or half size. If you are unsure, order anyway and contact us after checkout, we will help you confirm it before the ring goes into production.

Custom orders

Want the band narrower or wider than 3mm, a comfort fit interior, a brushed or matte finish instead of polished, pave along the top, a hidden halo beneath the stone, a different centre shape, engraving inside the shank, or a matching wedding band in the same width, 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.

Frequently asked questions

How does a 3mm band compare with a standard engagement ring band

Most solitaire shanks are between 1.5mm and 2mm wide. At 3mm this band is noticeably broader, closer to what many people would choose for a wedding band, so the ring reads as one substantial piece rather than a delicate one. It also distributes weight better under a large centre stone.

Is a wide band comfortable to wear every day

Yes, and many people find it more comfortable than a thin band, because the pressure is spread over a larger area rather than concentrated in a narrow line. The main adjustment is sizing, a wide band feels snugger at the same measurement, which is why we suggest considering a quarter size up.

What is a radiant cut diamond

A radiant is a rectangular or square stone with cropped corners and brilliant style faceting. It combines the elegant outline of an emerald cut with the fire of a round brilliant, scattering light in many small bursts rather than the broad flashes of a step cut. The trimmed corners also make it more robust than a sharp cornered shape.

Is a lab grown diamond 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, 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.

Does this ring come with a certificate

Yes. Every ring 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.

Can a wide plain band be resized

Yes. With no stones set into the shank there is nothing to work around, so a plain 3mm band is one of the easiest designs to resize, up or down, by a competent jeweller.

What does E colour VVS2 actually mean

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.

Why buy a lab grown diamond

A lab grown diamond gives you a materially identical stone for a fraction of the price of a mined equivalent, which is what makes a 4 carat or 5 carat radiant centre realistic on a normal budget. That matters more here than on most designs, because a solitaire has nowhere to hide, the size and quality of the single stone is the whole ring. Because the origin of every stone is documented from the moment it is grown, a lab grown diamond is conflict free by definition. Growing a diamond also avoids the open pit excavation, land disruption and water use that mining a comparable stone requires.
