Inclusion profile
Tip integrity is the key value driver. This selection avoids visible fractures at both points. The elongated body requires screening across the full keel length.
A long, blade-like black diamond that creates a severe silhouette and a distinct editorial presence. The marquise returns drama to the collection without abandoning the original black-and-gold discipline.

In-depth analysis
Light behavior
Light travels along the long keel line, creating quick linear flashes when the piece moves. Rose gold softens the blackness just enough to make it seductive rather than harsh.
Provenance and certification
A fashion-forward stone that still needs serious structural screening before setting. Gemological memo includes full tip analysis.
Wearability profile
Elongates the finger but requires protected tip settings for everyday confidence. Best for formal and editorial occasions.
Care and handling
Do not wear during activities that create lateral pressure on the tips. Store in a dedicated slot to prevent tip contact with other objects.
Investment note
Marquise black diamonds with intact tips and clean structural screening are among the harder pieces to source in large-carat categories.
Curatorial analysis
The marquise returns drama to the catalog without abandoning the original black-and-gold discipline.
Rose gold softens the blackness just enough to make it seductive rather than harsh.
It gives the collection a high-fashion silhouette that the old static grid only hinted at.
