The pendant for this hemp necklace is a double-terminated, (Points on both ends.  See last photo.) rose quartz crystal measuring: 3.3 x .8 cm. (1 1/4" x 3/8").

Doing macrame, with rose pink and white, colored hemp I used: twisted, rose quartz ovals;  faceted, amethyst and rose  quartz rounds;  smooth rose quartz rounds and larimar rondelles;  all strung on sturdy, 7-strand beading wire.

The length is adjustable;  starting at: 39.5 cm. (15 1/2"), up to 100 cm. (37 1/2").  
Just slip it over your head, and slide the lock knot to desired length.

This necklace is made for people of all sizes to wear any length.
If you would like it shorter, you can specify the length desired at time of purchase (no less than 60 cm. or 24" so it will still fit over your head), and I can easily shorten it.
