     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The case comprises a bottom case portion 10 which is circular in plan view, an upper case portion 11 which is also circular in plan view, and a holder 12 in the form of a band which extends around the peripheries of the case portions 10 and 11. 
     The holder 12 is formed of a non-transparent non-magnetic hard material, such as a metal. It is substantially circular in plan view and has ends 13 which extend radially outwardly forming a pair of flanges 14. In transverse cross-section the body of the holder 12 is part circular. The flanges 14 are each provided with holes 15 and 16. The holes 15 are for the provision of a locking device 17 and the holes 16 enable the case to be linked, or hooked to another object. The external surface of the holder 12 can be engraved with a decorative pattern. When the locking device 17 is unlocked the holder 12 can be expanded by moving the flanges 14 apart so as to allow the case portions 10 and 11 to be removed from or reinserted into the holder 12. In the region of the flanges 14 the holder 12 is provided with a curved recess 18 which receives locating portions 19 provided on case portions 10 and 11. 
     The upper case portion 11 is formed of a transparent material so that the contents of the case can be viewed. It has a domed portion 20 which forms a magnifying lens to enlarge the main displayed object 21. The periphery of the case portion 11 is part circular in section enabling it to seat in the holder 12. The case portion 11 has an annular downwardly extending flange 22 which is provided on its outer periphery with a portion 23 which engages in a recess 24 provided on the bottom case portion 10 so that the upper case portion 11 cannot be rotated relative to the bottom case portion 10. The upper case portion 11 is stepped internally to provide support for a top transparent support plate 25 and a non-magnetic metal support plate 26 which is retained by a stainless-steel wire spring clip 27 which engages in a groove. The upper case portion 11 also has an annular face 28 against which the bottom case portion 10 seats. 
     The bottom case portion 10 is formed of transparent material and internally is stepped and provided with a face 29 opposed to the face 28. The face 28 is provided with a groove 30 which receives a seal or sealant material so that an air and moisture and waterproof seal is provided. After the casing portions 10 and 11 have been brought together and sealed a hole or holes 31 are drilled in the peripheral portions at a location or locations where they will be covered by the holder 12 and a magnetic pin 32 is inserted in the or each hole 31. the location angle of inclination and size of the or each hole 31 will be different for each case produced and the location, angle, size and number of holes 31, and thus pins 32, will be recorded for future identification and be given a confidential serial number for security purposes. This will enable each case to be given a security identification. The bottom case portion 11 suppors a bottom transparent plate 33 and a non-magnetic steel bottom plate 34. the bottom transparent plate 33 defines with the bottom case portion 10 a sealed space 35. 
     The main displayed object 21 is located below the domed portion 20 and is supported by the support plate 26 and located between the support plate 26 and the plate 25. The support plate 26 is held in position by the wire spring clip 27 and provided on the underside of the support plate 26 is a layer of foamed material 36. The support plate 26 is thus upwardly biased by the foam material 36 and urges the object 21 into contact with the plate 25 so that the object 21 is held in a stable position. A description of the object 21 is provided on the underside of the bottom plate 34. Further displayed objects 37 are provided in holders 38 provided on the upper side of plate 25. The holders 38 may be fixed or they may be allowed to move freely on the plate 25. A description of the objects 37 can be provided on the underside of the bottom plate 34. 
     Provided between the layer of foamed material 36 and the plate 34 is a micro-film 39 of a certificate which the owner will have giving the contents, ownership details etc. 
     Within the space 35 are objects 40 of any desired shape or form which are movable within the space 35 and which provide a decorative appearance to the case. 
     The locking device 17 consists of a core or insert 41 formed of a soft metal or other suitable material which can be easily deformed. The core 41 is located within a button member 42 and extends through a stem portion 43 having a flared end 44. Mounted on the stem portion 43 is a stem portion 45 of a second button member 46. Initially the core 41, button member 42 and button member 46 are separate parts. When the flanges 14 have been brought together after the casing portions 10 and 11 have been assembled and inserted into the open holder 12, the stem 45 of button member 46 is inserted into the aligned holes 15 and the core or insert 41 inserted into the stem portion 43 and the stem 43 pushed into the stem 45. Opposed forces are then applied to the button members 42, 46, i.e. by a punch, to change the shape of the button members. Both ends of the core or insert 41 are deformed and prevent separation of the button members. 
     Removal of the holder 12 can only then be achieved by breaking and destroying the locking device 17, which cannot be re-used. 
     The plates 26 and 34 each have at their periphery a locating projection 47 which engages in a recess 48 in the respective casing portion. 
     The plate 33 is sealed to the bottom casing portion 10. 
     The items 21, 37 may be gemstones or valuable jewellery items.
