Signora Jewels builds this ring around the unusual 9.8 × 5.8 mm outline of a coffin cut center. Six prongs hold the photographed 1.50 ct diamond while polished branches cross around the setting, carrying individually modeled leaves above, below and alongside the stone.
The botanical shoulders spread to approximately 5.00 mm around the open vine sections, then return to a 2.30 mm lower shank. There are no accent diamonds in the leaves or branches. At approximately 7.40 mm high in the reference design, the center remains open underneath for cleaning.
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
- 1.50 ct reference center measuring approximately 9.8 × 5.8 mm
- Six-prong setting following the angular coffin cut outline
- No accent diamonds; the botanical detail is worked entirely in metal
- Sculptural leaf-and-vine branches crossing around the center
- Approx. 5.00 mm shoulders tapering to a 2.30 mm lower shank
The branches refuse to end neatly beneath the center. One vine climbs above the upper edge, another crosses beneath the diamond, and individual leaves project from both sides, making the center look caught inside the metalwork.

About Lab Grown Diamonds
The coffin cut reference center measures approximately 9.8 × 5.8 mm at 1.50 ct. Its elongated body, clipped upper corners and tapered lower outline give the six-prong setting several distinct contact points while leaving broad sections of the diamond visible between them.
Metal, Care & Fit
The reference construction uses approximately 6.30 g of 18K gold before the center is set. Yellow and rose gold make the modeled leaves and overlapping branches easiest to read; white gold and platinum put more visual emphasis on the center. Clean beneath the diamond and between the open vines with warm water, mild soap and a soft brush.
FAQ
What makes the coffin cut different in this ring?
The photographed center has an elongated 9.8 × 5.8 mm outline with clipped upper corners and a tapered lower section. The angular shape stands apart clearly because there are no accent diamonds around it.
How is the coffin cut center secured?
Six prongs hold the photographed 1.50 ct center around its angular perimeter. Open spaces between the contact points leave much of the diamond visible from the sides.
Are there diamonds set into the leaves and vines?
No. This design uses one center diamond and no accent stones, so the branches and individual leaves are sculpted entirely from the selected metal.
How high does the 1.50 ct reference setting sit?
The photographed construction is approximately 7.40 mm high. The selected center weight determines the final head dimensions as the setting scales through the available carat options.
Can this ring sit flush beside a straight wedding band?
The projecting leaves and crossing bypass branches make a perfectly flush straight-band fit unlikely near the center. A contoured band is better suited to following the irregular botanical outline.
