Neck Circumference and Pendant Weight Sizing Protocol
- Neck Circumference Offset: An 18-inch Princess chain fits loosely on a slender 13-inch neck, but behaves like a tight 16-inch Choker on a 15.5-inch neck. Always measure neck circumference with a soft tailor's tape and add 2 inches for a choker fit, or add 4 inches for a standard collarbone resting position.
- Pendant Weight V-Drop: Adding a heavy gemstone pendant naturally pulls the chain into a sharp downward 'V-shape', dropping the visual bottom of the necklace by an extra 1 to 2 inches compared to a plain lightweight chain.
