Signora Jewels sets the 10.8 × 6.5 mm coffin cut between branches that curl around the center rather than stopping beneath it. Six prongs hold the photographed 2.00 ct diamond, while six round green gemstones sit between polished vines and individually modeled leaves.
The shoulders spread to approximately 5.20 mm through the botanical sections before narrowing to a 2.30 mm lower shank. Open spaces separate the leaves, colored stones and crossing branches. At the photographed center weight, the setting stands approximately 8.00 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 10.8 × 6.5 mm
- Six round green gemstones totaling approximately 0.30 ct
- Six-prong setting following the angular center outline
- Sculptural leaves and crossing vines worked into the open shoulders
- Approx. 5.20 mm shoulders tapering to a 2.30 mm lower shank
The green stones are worked into the vine rather than arranged as a conventional straight side-stone row. Three rounds sit on either side of the center among raised leaves and curling branches, putting small points of color against the angular white center.

About Lab Grown Diamonds
The coffin cut reference center measures approximately 10.8 × 6.5 mm at 2.00 ct. Its elongated body, clipped upper corners and tapered lower outline give the six-prong setting distinct contact points while leaving broad sections of the diamond visible between them.
Metal, Care & Fit
The reference construction uses approximately 6.65 g of 18K gold before the stones are set. Yellow and rose gold bring out the modeled leaves and contrast with the green side stones; white gold and platinum put more visual separation between the botanical metalwork and colored accents. Clean beneath the center and between the open branches with warm water, mild soap and a soft brush.
FAQ
What are the six colored stones beside the center?
Six round green gemstones totaling approximately 0.30 ct sit through the leaf-and-vine shoulders. Three are positioned on either side of the photographed coffin cut center.
How is the coffin cut center secured?
Six prongs hold the photographed 10.8 × 6.5 mm center around its angular outline. The spaces between the prongs leave much of the 2.00 ct reference diamond exposed to view.
How wide are the botanical shoulders?
The shoulders reach approximately 5.20 mm through the leaf-and-vine sections before tapering to a 2.30 mm lower shank. Open spaces between the branches break up that width.
How high does the 2 ct reference center sit?
The photographed setting is approximately 8.00 mm high. The center setting scales with the selected diamond weight while retaining the surrounding botanical shoulder design.
How should I clean around the green side stones?
Use warm water, mild soap and a soft brush around the six round gemstones and from beneath the open vine shoulders. The spaces between the leaves and branches give direct access to areas where lotion can collect.
