Jewellery definition clarifies which adornments and precious stones qualify as jewels for legal classification and valuation. Definitions centralise the legal characterisation of movable adornments: Jewellery is treated as gems or ornaments sold or made by jewellers, emphasising precious stones in mountings and collective use as adornment. Jewel denotes an article of value used for personal adornment, particularly items of gold, silver or precious stones and individual precious stones worn as ornaments.
