This fee is charged by the jade stone laboratory for certifying the jade piece, we provide the service to take it there. Their location is conveniently across from our jade workshop.
Please see the pictures for the sample of what the certificate looks like.
There are various laboratories that are widely accepted in our industry: - Hong Kong Gems Laboratory - Hong Kong Kowloon Jade & Jewellery Laboratory - Hong Kong Jade & Stone Laboratory
Typically we use the most convenient one in terms of the time scheduling at that instance when we call for appointments. If you have a preference to a particular laboratory, please make sure to let us know in advance to avoid any misunderstanding. Thank you!
