So the description does not give the dimensions of this pendant, other than reviews (of the gold version and the versions with the black cord) saying that it is quite big and has weight.
For future purchasers, it is 4.5 cm long by 3 cm wide, and weighs 24 grams on my kitchen scale, or the weight of five Canadian quarters. This does make it among the largest and definitely heaviest necklaces I own, but the weight, I find, is nice and soothing.
The cord requires you to tie it in a knot behind ...
