The included Moldavite weights 4.56 gram from Chlum, Czech Republic.
The stone perfectly fits to its setting and I have ensured to stay in place with waterproof glue.
So if you jump in a lake and keep the amulet in place then it makes the pendant more fragrant while drying :)
Yes! The wood can be wet, but better avoid of perfume,shampoo and things like these .
