IGemsOnCurve

Returned by GemsOnCurveApi — a row of identical gems distributed along a parent curve. The “mother” here is the curve, not a single gem: the inherited GemShape / GemMaterial / GemCaratWeight describe the gem template that gets repeated along the curve. Read-only — no setters. Adds to IGemSetting:

Member	Meaning
CurveId	Guid of the parent curve
StoneCount	Number of gems in the row
