FAQ

Q: Is the shared prong setting durable enough for retail diamond pendant collections?
A: Yes. The continuous frame reinforces each shared prong along the heart border, keeping the structure rigid while preserving the open, lightweight silhouette for everyday retail wear.

Q: Can this open heart pendant CAD model be produced from a single open heart pendant STL file?
A: Yes. The open heart pendant STL file supports direct wax printing and casting across multiple metals without requiring a separate model for each alloy.

Q: How many diamonds does this pendant require for production?
A: The design uses 16 diamonds total — 8 round and 8 marquise stones — set along the open heart frame for a combined weight of 0.821 CT.
