The pendant for this hemp necklace is a double-terminated, (Points on both ends. See last photo.) amethyst stone point measuring: 3.3 x 1 cm. (1 1/4" x 1/4").
Doing macrame, with purple colored hemp, I used: faceted and smooth, amethyst rounds and larimar rounds all strung on 7-strand beading wire.
The length is adjustable; starting at 34 cm. (13 1/2"), up to 75.5 cm. (29 1/2").
Just slip it over your head, and slide the lock knot to desired length.
