A coffin cut lab grown diamond bezel engagement ring from Signora Jewels.
The photographed design carries a 2.00 ct coffin cut measuring approximately 10.5 × 6.5 mm, enclosed by a full geometric bezel with no accent diamonds. Approx. 2.00 ct total. IGI certified.
Made to order in 11 metals: silver, 9K/14K/18K gold (yellow, white, rose) and platinum.
Free insured express shipping over $500, duties prepaid to the US, UK and Canada, 30-day returns.
Each metal color is shown in the photos. Choose a 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct center and your preferred metal from the options on this page.
Signora Jewels follows the 10.5 × 6.5 mm coffin cut with a complete rim of metal rather than breaking its outline with prongs. At the photographed 2.00 ct weight, the bezel traces the clipped upper corners, long tapered sides and narrow lower edge of the diamond.
The rest of the ring stays deliberately plain. Cathedral supports rise from shoulders measuring approximately 2.30 mm, meeting the bezel without adding side stones or decorative metalwork. The lower shank is about 2.20 mm wide and 1.85 mm thick, while the reference setting reaches approximately 6.30 mm high.
Design highlights
- Coffin cut center options: 1 ct, 1.5 ct, 2 ct, 2.5 ct, 3 ct, 3.5 ct, 4 ct or 4.5 ct
- 2.00 ct reference center measuring approximately 10.5 × 6.5 mm
- Full geometric bezel surrounding the entire diamond perimeter
- No accent diamonds or pavé along the shank
- Cathedral-supported shoulders measuring approximately 2.30 mm
- Approx. 6.30 mm reference setting height with a 2.20 mm lower band
The bezel makes the unusual outline impossible to miss. Its polished border repeats every change of direction in the coffin cut, while the undecorated shank leaves nothing beside the center to compete with that geometry.

About Lab Grown Diamonds
The coffin cut reference center measures approximately 10.5 × 6.5 mm at 2.00 ct. Its clipped upper corners, long angled sides and narrower base create a distinctly geometric outline. The full bezel follows those edges closely instead of placing prongs over them.
Metal, Care & Fit
The reference construction uses approximately 5.40 g of 18K gold before the diamond is set. Yellow and rose gold create a strong border around the white center, while white gold and platinum make the bezel visually recede toward the diamond. Clean around the underside of the setting with warm water, mild soap and a soft brush.
FAQ
How does the full bezel protect this coffin cut?
The bezel surrounds the complete perimeter of the diamond with metal. That gives the angular 10.5 × 6.5 mm reference center a continuous protective edge instead of leaving corners between exposed prongs.
Does this ring have any side or accent diamonds?
No. The photographed design contains one 2.00 ct center diamond and no accent stones, leaving the polished bezel and plain shank completely free of pavé.
How high does the 2 ct reference setting sit?
The photographed construction is approximately 6.30 mm high. Cathedral supports rise from the shoulders into the bezel, keeping the center connected to the shank from both sides.
How wide is the band?
The lower shank measures approximately 2.20 mm wide and 1.85 mm thick, with shoulders of approximately 2.30 mm near the setting. The nearly consistent width keeps attention on the geometric center.
Which metal gives the coffin outline the strongest contrast?
Yellow and rose gold create the clearest visible border around the white diamond. White gold and platinum keep the bezel closer in tone to the center while preserving the same angular outline.
