Emerald-cut bracelet / CAD discussion

A rhythm of white and ruby.

36 stones. Three size studies. One unscaled CAD comparison. Proposed Pt950/Ru, subject to Elena’s approval.

Design discussion — not for manufacture. The 215.9 mm target is the stone section only, excluding the clasp. It is not a wrist measurement. Your wrist estimate is 8 inches or slightly less (~203.2 mm); it is not confirmed, and wrist width and thickness remain unmeasured.

Equal world scale / no stone rescaling

Three sizes, separated from three different lengths.

Stone-section length, closed hinge-path perimeter and inner wearing perimeter are different quantities. None is a personalized fit prediction. Unknown dimensions are deliberately marked, not substituted with gem-weight estimates.

Before a personal fit study

Reference, not your wrist.

Provide wrist circumference at the intended wearing position, wrist width and thickness, preferred ease, and desired drape. The illustrated reference is generic and cannot establish comfort, clearance or closure on your wrist.
