Emerald Cut Lab Grown Diamond Ring with Hidden Halo on a Wide Flat Band

Emerald Cut Lab Grown Diamond Ring with Hidden Halo on a Wide Flat Band

An emerald cut lab grown diamond in four claws raised above a wide flat band, with a hidden halo of small round diamonds set in a milgrain edged collar directly beneath the stone.

Seen from above this is a bold, almost architectural ring, a large step cut diamond sitting on a broad plane of polished metal with nothing else on it. Turn it to the side and the hidden halo appears, a fine band of diamonds ringing the base of the setting with beaded milgrain along both edges.

Lifting the stone off a wide band is a deliberate decision. A large flat shank has a lot of visual weight, and setting the diamond flush into it would make the head look sunken. Raising it clear, and putting a bright collar underneath, keeps the stone reading as a separate object above the metal.

The band itself is straight sided and mirror polished, of even width all the way round, with the edges lightly softened so it sits comfortably against the finger.

Band details

A wide flat shank of even width around the full circumference, mirror polished on the outside and comfort domed on the inside. There is no taper, which is what gives the ring its solid modern balance.

Metal options

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. Yellow gold, shown here, is the strongest choice because the broad polished face is the main surface of the ring.

Ring size

Every ring is made to order in your size. Select your size at checkout. A wide band fits more snugly than a narrow one, so if you are between sizes we usually recommend the larger. Contact us for advice before we begin.

Custom orders

We can change the center carat weight, the color and clarity grade, narrow the band, or remove the hidden halo for a completely plain look. Write to us at https://mapplegems.com/pages/contact and we will quote your version.

Frequently asked questions

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.

What is a hidden halo
A ring of small diamonds set into the collar under the center stone. It is invisible from directly above and visible in profile, adding light under the stone without changing the outline of the ring.

Should I size up for a wide band
Usually yes, by about a quarter to a half size. Tell us your usual size and we will advise.

Can this ring be resized later
Yes, though a wide band takes more work than a slim one. Your first resizing with us is free.

How is this different from your other wide band rings
Our wide flat cigar band ring sets the stone low into the face with no accents. This design lifts the stone above the band and adds a milgrain edged hidden halo underneath.

Does a wedding band sit flush against it
Yes at the band, which is straight and flat. The raised head means the two rings meet at the shank rather than under the stone, which most people prefer with a wide band.

How do I clean it
Warm water, mild soap and a soft brush, working under the head where the hidden halo sits.

Which metal should I choose
Yellow gold for the boldest contrast between metal and diamond. White gold or sterling silver if you want the band to recede. Rose gold for something warmer and softer.

Why buy a lab grown diamond

A lab grown diamond gives you the same material as a mined stone with a documented origin. A wide band needs a large stone to stay in proportion, and lab grown is what makes a 4 or 5 carat emerald cut realistic on a ring like this.
