Design a modern setting around the antique diamond’s actual outline and condition. Start with accurate face-up measurements, side views and a map of the girdle so the setter can plan the seats and protection.

Resolve height early

The 5.02 ct H VS2 old mine cushion measures 10.39 × 9.11 × 6.41 mm. Its depth makes the side view particularly useful when planning a ring intended to sit close to the finger. The design needs room for the pavilion and clearance beneath the culet.

Place support where the stone needs it

Hand-cut corners and shoulders may differ. A thin girdle section, natural or earlier repair can affect prong position and bezel coverage. Mark these areas before approving the drawing, then agree how they will be protected during setting and daily wear.

Compare white and yellow metal beside the loose diamond. Keep side-stone scale and gallery detail in proportion to its face, and check how a wedding band will sit beside the finished ring.

Bring the condition notes to the workshop discussion. Our high-jewelry page shows the design and setting process.
