[0014] FIG. 5 illustrates an enlarged front view of a block of the device of FIG. 1;

[0015] FIGS. 6 and 7 illustrate the device of FIG. 1 respectively in an unlocked condition and in a removal condition of the jewel from the device.

BEST MODE OF CARRYING OUT THE INVENTION

[0016] With reference to FIG. 1 to 5, numeral 1 indicates the removable jewel support device comprising an ornamental element 3 commonly and mainly consisting of one or more elements, also combined together, which are selected among various materials, for example precious stone, pearl, precious metal element (gold, silver, platinum, etc.), or less valuable materials (copper, brass, silver laminates, steel, etc.). The combination of the device 1 and jewel 2 defines both jewelers and costume jewelry.

[0017] The jewel 2 consists of the ornamental or decorative element 3 and a hooking element 4 provided with a stem 4a and a bulge or bulb 4b. The ornamental element 3 is locked to the hooking element 4 in a known way, for example by gluing, welding or supported by staples. It is also provided that the ornamental 3 and hooking 4 elements are preferably of the same material, for example gold, silver, platinum or steel.

[0018] In the preferred embodiment, the device 1 essentially consists of a base 10 having a first housing 5 made in an almost central area which has a front opening 6 and a rear opening 8.

[0019] The base 10 provides a second housing 9 which externally surrounds the first housing 5 and which is intended to accommodate the jewel 2 inside it, even partially.

[0020] The device 1 also comprises a fixing element 11 which is constituted by a cover 11a provided with a front hole 12a and a hollow block 11b with front opening and provided on its back with a rear hole 12b.

[0021] An elastic ring or O-ring 7 is housed inside the internal cavity of the hollow block 11b, while the cover 11a is arranged on the front opening 6 of the block 11b so that the O-ring 7 is locked inside the fixing element 11, so that the axis of the hole of the O-ring is almost axial with the axis of the front 12a and rear 12b holes.

[0022] The fixing element 11 is cylindrical and is locked into the first housing 5 by embedding and/or gluing and/or welding and/or interlocking.

[0023] A variant, not illustrated, of the device 1 provides to produce a plurality of first housings 5, each assigned to house a respective fixing element 11. Obviously, the hooking element 4 will provide corresponding stems for coupling with each respective fixing element 11.

[0024] The device 1 also provides a support element 13 protruding from the edges of the second housing 9, preferably fixed at the sides of the base 10 and assigned to allow for the suspension of the device 1 to a jewelry or costume jewelry element chosen, for example, among a chain, a necklace, a ring, a latch element, a pendant, etc.

[0025] The second housing 9 has a substantially cylindrical or preferably straight prism shape.

[0026] The use of the device 1 for defining the jewel provides that the fixing element 11 is inserted in the first housing 5 of the base 10 in an assembly condition A in which the stem 4a is inserted into the fixing element 11 passing from the front hole 12a, through the O-ring 7 and the rear hole 12b, until the bulge 4b protrudes, even partially, from the rear opening 8 in correspondence with a support condition S of the removable jewel 2 by the device 1.

[0027] In the support condition S, the front hole 12a, the rear hole 12b and the rear opening 8 are coaxial through holes and therefore arranged on the same axis as the stem 4a.

[0028] In this supporting condition S, the jewel is firmly anchored to the base 10 since the stem 4a, the bulge 4b and the attachment portion of the stem 4a to the bottom of the hooking element 4 are in close contact with the internal walls of the O-ring 7.

[0029] Furthermore, the jewel 2 is further locked to the base 10 because it is partially housed in the second housing 9 and it is practically embedded or in any case firmly locked therein.

[0030] Referring now to FIGS. 6 and 7, the device 1 further comprises a jewelry accessory 14 assigned to contact the bulge 4b to allow for the latter to be pushed beyond the O-ring 7 in the passage of the device 1 from the support condition S to a removal condition R thereof from the device 1.

[0031] It has been advantageously shown that the jewel 2 is both removable from the base 10, thus being interchangeable, and firmly locked to the jewel support device in the support condition S.
