Patent Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention generally relates to jewelry such
as rings or pendants and, more particularly, to an enhanced setting
in which a plurality of cut and polished stones, especially diamonds,
is mounted.
[0003] 2. Description of the Related Art
[0004] It is conventional to set a diamond or other precious or
semi-precious stone on a jewelry item such as a ring by using a
plurality of prongs to hold the diamond or other main stone such
that the table, i.e., the flat upper surface of the main stone,
is visible from the top or front of the ring when worn. In order
to enhance the appearance of the main stone, it is known in the
art to mount complementary stones on the ring or on the setting
for the main stone. Thus, U.S. Pat. No. 5,664,440 and U.S. Pat.
No. 5,868,008 disclose a single complementary stone underneath the
main stone. U.S. Pat. No. 4,936,115; U.S. Pat. No. 6,012,302; U.S.
Design Patent No. D-315,698 and U.S. Design Patent No. D-412,681
disclose the use of a plurality of complementary stones at the sides
of and below the main stone. U.S. Design Patent No. D-393,227 discloses
the use of a plurality of complementary stones arranged circumferentially
along the annular shank of a ring below the main stone.
[0005] As attractive and advantageous as these known settings and
assemblies are for use as jewelry or decoration, it would be desirable
to improve the amount of light directed by the complementary stones
into the main stone as viewed from the front of the main stone.
It would be further desirable if the complementary stones themselves
are directly visible, or at least partly visible, from the front
of the jewelry.
SUMMARY OF THE INVENTION
OBJECT OF THE INVENTION
[0006] Accordingly, it is a general object of this invention to
enhance the appearance of a main stone mounted on a jewelry item.
FEATURES OF THE INVENTION
[0007] In keeping with the above object and others which will become
apparent hereinafter, one feature of the present invention resides,
briefly stated, in a jewelry assembly which comprises a support
extending in a circumferential direction at least partly about a
support axis, and a setting including a base mounted on the support,
an upper stone mounted at an elevation above the base, and a plurality
of lower complementary stones mounted on the base, at least one
of the lower stones being overlaid by the upper stone.
[0008] In accordance with a first embodiment of this invention,
the lower stones are arranged in a row extending in a circumferential
direction at least partly about a setting axis perpendicular to
the support axis. More particularly, the base includes arcuate wall
portions bounding an arcuate channel in which the lower stones are
held. The lower stones have individual axes of symmetry which intersect
one another at a common point. The lower stones are cut and polished
and have individual tables lying in planes which intersect one another.
[0009] Hence, according to the first embodiment, in the case wherein
the support is an annular shank of a ring having a width dimension
that extends along the support axis, the lower stones are arranged
in a row that extends widthwise of the shank in a "saddle-type"
setting that sits astride the shank. The tables of the lower stones
face at least partly toward the front to improve the appearance
of the setting and to increase the amount of light collected, reflected
and refracted back toward a viewer.
[0010] In accordance with a second embodiment of the invention,
the lower stones are arranged in a linear row that extends generally
widthwise of the shank of the ring. The lower stones have individual
axes of symmetry parallel to one another. The individual tables
of the stones lie in a common plane parallel to the table of the
upper stone.
[0011] Each of the stones is cut and polished and is a precious
or semi-precious stone or gem. Preferably, diamonds are used. The
invention is best implemented in a diamond engagement ring, but
is also applicable for usage in pendants and earrings.
[0012] The novel features which are considered as characteristic
of the invention are set forth in particular in the appended claims.
The invention itself, however, both as to its construction and its
method of operation, together with additional objects and advantages
thereof, will be best understood from the following description
of specific embodiments when read in connection with the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Reference numeral 10 in FIG. 1 generally identifies a setting
including a base 12, a plurality of prongs 14, 16, 18, 20 extending
upwardly away from the base 12, and an upper stone 22 held by the
prongs at an elevation above the base. Upper stone 22 is, as shown
in FIG. 4, cut and polished with many facets and has a planar table
24, a crown 26, a pavilion 28, a vertex 30, and an axis 32 of symmetry.
Upper stone 22 is preferably a gemstone, such as a diamond, but
could be any other precious or semi-precious gem.
[0021] The setting 10 can be mounted on diverse items of jewelry,
for example, a ring having an annular support or shank 34 extending
at least partly about, and preferably completely around, a support
axis 50. As best seen in FIG. 2, the shank 34 has a width dimension
"W" extending along the support axis.
[0022] The base 12 is mounted on the shank 34 and includes a pair
of arcuate frame portions 36, 38 bounding a channel in which a plurality
of lower complementary stones 40, 42, 44, 46 is mounted in a row
extending widthwise of the shank 34 and in a circumferential direction
at least partly about a setting axis 48 perpendicular to the support
axis 50. Each lower stone is cut and polished and has individual
axes of symmetry 52, 54, 56, 58 (see FIG. 4) intersecting one another.
The stones have individual tables lying in intersecting planes.
Each lower stone is preferably a gemstone, such as a diamond, but
could be any other precious or semi-precious gem.
[0023] In accordance with the embodiment of FIGS. 1-4, the appearance
of the upper stone 22 is enhanced by the lower stones 40, 42, 44,
46 which are arranged in a "saddle-type" base which sits
widthwise astride the shank 34. The tables of the lower stones face
at least partly upwardly toward the table 24 of the upper stone
and in a curved path by which the lower stones collect, reflect
and refract more light into and through the upper stone.
[0024] The lower stones can be set in the base by any of several
setting techniques, such as channel setting, nick setting, prong
setting, pave setting and burnishing. The size and number of the
lower stones is adjustable. The setting 10 can be assembled as a
discrete unit and can thereafter be mounted in a separate step on
the shank. When production warrants, the setting can be pre-attached
to the ring during casting or stamping.
[0025] The upper stone need not be a round center diamond as illustrated,
but could be a square-shaped, rectangular-shaped, oval-shaped, or
cushion-shaped, center stone. The upper stone need not be held by
four single prongs as illustrated, but could be four double-prongs,
four triple-prongs, half-bezel prongs, less than half-bezel prongs,
v-shaped prongs, or fishtail prongs.
[0026] In the embodiment of FIGS. 5-7, the upper stone 60 is a
marquise and is a pointed oval, rather than the round stone 22 of
FIG. 1. The upper stone 60 is held by a pair of prongs 62, 64, rather
than the four prongs of FIG. 1. A plurality of lower complementary
stones, including a group of lower stones 66, 68, 70 is arranged
in a row extending transversely and linearly across the width of
an annular shank 72 of a ring 74. The shank 72 extends around a
support axis 76. the linear row of the lower stones can extend along
the support axis 76, or, as shown in FIG. 6, can extend at an angle
relative to the support axis.
[0027] For enhanced appearance, the group of lower stones 66, 68,
70 can include additional groups of stones 78 extending along arcuate
paths on axial ends of the shank, and further groups of stones 80,
82 extending circumferentially of the shank at opposite sides of
the upper stone.
[0028] The lower stones 66, 68, 70 are overlaid by the upper stone
60, have individual axes of symmetry which are parallel to one another,
and have individual tables lying in a common plane that is parallel
to the table of the upper stone 60. The lower stones 66, 68, 70
collect, reflect and refract light into and through the upper stone
for an enhanced appearance.
[0029] It will be understood that each of the elements described
above, or two or more together, also may find a useful application
in other types of constructions differing from the types described
above.
[0030] While the invention has been illustrated and described as
embodied in a jewelry assembly, it is not intended to be limited
to the details shown, since various modifications and structural
changes may be made without departing in any way from the spirit
of the present invention.
[0031] Without further analysis, the foregoing will so fully reveal
the gist of the present invention that others can, by applying current
knowledge, readily adapt it for various applications without omitting
features that, from the standpoint of prior art, fairly constitute
essential characteristics of the generic or specific aspects of
this invention and, therefore, such adaptations should and are intended
to be comprehended within the meaning and range of equivalence of
the following claims.
[0032] What is claimed as new and desired to be protected by Letters
Patent is set forth in the appended claims. |
