Step 1
Design & Selection
We finalise your design and hand-pick the certified center stone.
Save 20%An emerald cut lab grown diamond set north to south in four slim claws, on a band that is flat across its top surface rather than rounded, engraved along its length and edged with fine milgrain. No accent stones anywhere on the ring.
Flat is the right profile for an engraved band and rounded is the wrong one, for a reason that has nothing to do with taste. Engraving is cut with a graver held at a consistent angle, and on a curved surface that angle changes continuously as the tool travels across the width, so the pattern shallows toward the edges and never quite reads as one clean design. A flat top gives the graver a constant plane to work on. The cuts stay the same depth across the full width, the pattern holds its shape, and the milgrain at each edge finishes it with a defined border instead of trailing off round the curve.
The shank is flat across its top surface and even in width, engraved along its full length and finished with milgrain beading at both edges. The outer corners are lightly softened so the band does not feel sharp, and the inside is rounded and smooth. Because it carries no stones it resizes easily and can be re engraved if the pattern ever softens.
Choose from 925 sterling silver, or 10K, 14K and 18K gold in yellow, rose or white. Yellow gold is shown here and warm metal reads engraving best, because the cut lines hold shadow and the pattern is legible from a distance. Rose gold does the same slightly more gently. White gold and sterling silver reduce the engraving to a fine texture rather than a visible pattern, which suits people who want the surface without the decoration.
This ring is available in a full range of US sizes. Select your size at checkout. If you are unsure of the size, contact us and we will help you measure at home before the ring is made.
We make every ring to order, which means the design can be adjusted. Ask us for a different engraving pattern, a plain flat band, an east to west orientation, a hidden halo, a wider band, a different centre shape or a matching engraved wedding band. Write to us through https://mapplegems.com/pages/contact and a member of our team will reply with drawings and a quote.
Why is the band flat rather than rounded?
Because engraving needs a constant plane. On a curved surface the graver angle changes as it crosses the width and the pattern shallows toward the edges. A flat top keeps the cuts even all the way across.
Is a flat band comfortable?
Yes. The flat face is on the outside. The inner surface is rounded and polished exactly like any other band, and the outer corners are softened so nothing feels sharp.
Why does an emerald cut look so clear?
It is a step cut with long parallel facets arranged like stairs rather than the many small triangular facets of a brilliant. You get broad flashes of light and an open view straight into the stone.
Does clarity matter more with an emerald cut?
Yes. There is nowhere for inclusions to hide, which is why the centre stone here is VVS2, a grade at which nothing is visible without magnification.
Is a lab grown diamond a real diamond?
Yes. A lab grown diamond has the same carbon crystal structure, hardness, refractive index and fire as a mined diamond. The only difference is that it was grown in a controlled environment rather than pulled from the ground.
Will I receive a certificate?
Yes. An IGI certificate for the center stone is included with every order at no additional cost.
How do I care for an engraved band?
Warm soapy water and a soft toothbrush worked along the cut lines. Avoid heavy polishing cloths, since aggressive polishing is what wears engraving and milgrain flat over time.
A lab grown diamond gives you the same optical and physical properties as a mined stone at a far better price for the size and quality. Because the growth conditions are controlled, high color and high clarity stones like the E VVS2 used here are available in large carat weights that would be rare and costly in mined goods. It is also a traceable choice, with a known origin and no mining footprint.
