एकशीर्षकः शुद्धो हारः ॥ कZ_०२.११.१७ ॥
ekaśīrṣakaḥ śuddho hāraḥ
A “pure necklace” (śuddha hāra) is the single-headed/single-terminal type (ekaśīrṣaka).
A baseline/standard form (and possibly unmixed material composition) used as the reference category for comparison and valuation.
Terminal structure affects workmanship, material use, and therefore valuation—critical for procurement and audit.
