Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates generally to jewelry and gemstone
settings and more particularly to a gemstone setting wherein a
plurality of small diamonds are set to simulate the appearance of a
large diamond.
[0003] 2. Description of the Related Art
[0004] Different types of gemstone settings are employed by
jewelers to hold different types of gemstones in place. These
settings secure the gemstones and also add to the aura of the
gemstones by significantly enhancing their brilliance and
scintillation. The selection of settings is determined by the shape
and cut of a gemstone. Large gemstones such as, for example, a
large standard round brilliant (SRB) diamond are most coveted in
any jewelry setting. However, large gemstones are very expensive,
whereas settings wherein a plurality of small to very small
gemstones is employed offer an affordable choice to buyers. For
example, melee diamonds--small diamonds wherein the diamond weight
range from 0.001 carats to 0.18 carats--are used in micro pave
settings.
[0005] The gemstone settings in the prior art use small to very
small diamonds as accent diamonds to the primary diamonds. These
small accent diamonds accentuate large primary diamonds. Further,
the arrangements of small diamonds in these settings do not follow
an asymmetric pattern to present a single organic unit as standard
gemstone shape. The arrangement as a single shape does not offer
the appearance of parts of an SRB diamond such as for example, a
pavilion, a culet, a table, a girdle and a crown, and various other
standards that are associated with standards gemstone shapes. A
gemstone setting wherein very small gemstones set so as to present
an appearance of a large gemstone, such as, for example, a large
SRB diamond, is absent in the prior art.
[0006] Therefore, a gemstone setting is needed that (1) sets very
small gemstones so as to simulate the appearance of a large
gemstone and all the critical gemstone parts and features with
added brilliance and scintillation and (2) provides an alternative
to a large gemstone setting is needed.
SUMMARY
[0007] A gemstone assembly is disclosed. The gemstone assembly
includes a multidimensional base having an upper portion and a
lower portion joined together to form the multidimensional base.
The multidimensional base is adapted to facilitate the setting of
the plurality of gemstones to simulate at least a culet, a
pavilion, a girdle, a crown, a table and a plurality of facets to
provide the simulated look of a large gemstone.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
[0029] The embodiments of the invention shown and discussed herein
are illustrative of modes of application of the present invention.
Reference to details in this discussion is not intended to limit
the scope of the claims to these details, or to the figures used to
illustrate the invention.
[0030] A gemstone setting 100 in accordance with the present
invention that uses a plurality of small diamonds that are set
close together in the shape of a three-dimensional faceted diamond.
Referring to FIG. 1, the gemstone setting 100 includes a prong
assembly 102 having four prong members 104, 106, 108 and 110, a
prong assembly base 112 and a prong assembly end 114. The prong
members 104, 106, 108 and 110 have upper ends 104a, 106a, 108a and
110a. The prong assembly 102 holds a gemstone assembly 116 between
four prongs 104, 106, 108 and 110. The gemstone assembly 116 has a
plurality of gemstones 118 that is set in such a fashion that
similar to a real gemstone, the gemstone assembly 116 has a table
120, a crown 122 and a girdle 124. In this embodiment preferably
melee diamonds are used in a gemstone assembly. However, it is
understood that diamonds having a wide variety of sizes may be used
in accordance with the present invention, instead of melee diamonds
in alternative embodiments.
[0031] Referring to FIG. 2, the gemstone assembly 112 is set with
the plurality of diamonds 118 such that the gemstone setting 102
simulates the appearance of a standard cushion cut gemstone. The
gemstone setting 102 appears to have rounded corners and larger
facets that are so characteristic of a standard cushion cut
gemstone. The gemstones 118 are set such that only the table of
each gemstone 118 is exposed. The gemstone assembly has a table
periphery 125 and a crown periphery 126.
[0032] Referring to FIG. 3, the gemstones are paved in rows within
the table and the crown planes. A plurality of imaginary dotted 128
lines that is illustrated represent the paths that the gemstones
118 to be set. The gemstones 118 are set within a plurality of
imaginary rectangles 130 defined by the intersecting and/or
parallel dotted lines 128. The standard micro pave setting
technique is used for setting the gemstones 118. The standard micro
pave setting preferably employs gemstones of uniform size. However,
in accordance with the present invention, the gemstones 118 that
are used in the gemstone setting constructed may or may not be of a
uniform size. The gemstones are set within the rectangles from row
to row creating a pattern that resembles a honeycomb.
[0033] Referring to FIGS. 4A and 4B, the gemstones 118 of uniform
size are set very close to each other. The arrangement of gemstones
118 is held in place by beads 134. A plurality of carefully drilled
and tapered holes 132 is created in the metal. Each stone 118 is
placed in the hole132 and the metal is pushed over the edges of the
stone. Using industry standard tools, a bead like prong is created
out of the metal on the stone and the excess metal is removed and
the bead setting for the gemstones 118 is accomplished.
[0034] As shown in the figure, a plurality of bead like prongs 134
is represented by dotted triangles at the four corners of the
rectangles 128. The plurality of gemstones 118 are clustered
together with little or no metal showing within the beads 134.
Although each stone 118 is set in four beads 134 at four corners,
each stone 118 may share a common bead 134 with the adjacent stone
118. The beads 134 and the gemstones 118 are at same level and
there is little metal between adjacent gemstones 118.
[0035] It is noted here that the bead setting is also achievable
with tiny prongs already cast in the metal. Melee diamonds are set
into a design. The design has multiple tiny little prongs perfectly
formed in the prototype or wax. Preferably investment casting is
used for the purpose. However, other process may also be used.
[0036] The highly precise setting of very small diamonds 118 into
the chosen design and shape is accomplished. In some embodiments,
the plurality of gemstones 118 is preferably set to be almost on
the same level as that of the surface on the ring. However, in
other embodiments the gemstones may not be on the same levels as
that of the surface ring.
[0037] Referring to FIG. 5, the prong assembly 102 holds a gemstone
assembly 116 between four prongs 104, 106, 108 and 110. The
gemstone assembly 116 has a plurality of gemstones 118 set on a
multidimensional base 136 to simulate a large gemstone, such as,
for example an SRB diamond. The micro pave setting is employed on
the gemstone assembly 116 such that the tables of the stones 118
are exposed. In this particular embodiment, at the bottom of the
gemstone assembly 116 a metal vertex or culet 136 is provided. The
vertex 136 simulates a culet of a large gemstone. However, the
separate vertex or culet 136 may be absent in some other
embodiments and/or may be a small diamond or group of diamonds.
[0038] Referring to FIGS. 6 and 7, a multidimensional base 138
includes an upper portion 140 and a lower pavilion portion 142. The
upper portion 140 has a table portion 144 and a crown portion 146.
The upper portion 140 also has an upper girdle portion 148 below
the crown portion 146. The multidimensional base 138 has at least
two projected inserts 150 projecting out of the bottom.
[0039] The pavilion portion 142 has a plurality of faces 152. The
pavilion portion 142 is preferably hollow from inside and has a
lower girdle portion 154 that includes at least a pair of holes 156
located on a lower girdle top surface 158 to receive inserts 150.
The pavilion portion 142 has a bottom insert 160 that engages with
the prong assembly 102.
[0040] The upper and the lower pavilion portions 140, 142 are moved
up and down appropriately along the directions indicated by the
bidirectional arrow to achieve engagement and disengagement. Both
portions 140, 142 meet to form the complete multidimensional base
138. The upper girdle portion 148 and the lower girdle portion 154
combine and define the girdle 124.
[0041] Referring to FIGS. 8-11, the disengaged multidimensional
base 138 having a plurality of stone seats 162 formed in the metal
is shown. The stone seats 162 are formed in rows on the table 120,
the crown 122 and the pavilion portion 142. The gemstones 118 that
are set in the seats 162 which may range from less than a
millimeter to slightly larger, up to 3 mm. Although a variety of
gemstones may be used diamonds are the preferred gemstones used
micro pave designs. The diamonds that are used in the micro pave
designs may be as tiny as 0.0025 carat but generally are not larger
than 0.035 to 0.04 carat in size.
[0042] Another important feature of the gemstone setting 100, in
accordance with the present inventions is that the multidimensional
base 138 is separable. The use of a separable base 138 allows a
jeweler to create gemstone assemblies that simulate or resemble a
variety of standard gemstone shapes, as faithfully as possible. The
separable base 138 allows a jeweler to maintain strict focus on
implementing various norms pertaining to each stone shape such as,
for example, proper width and height proportions and/or angle
between the table and the crown. The separable base 138 allows a
jeweler to expedite the stone setting process. The use of separable
parts also allows a jewelry user to conveniently replace the base
portions conveniently when they are damaged.
[0043] Once the stones 118 are set in stone seats the gemstone
assembly 116 is complete and ready to be mounted in the prong
assembly 102, like a large gemstone. Depending upon the design
need, the jeweler may opt either for the bottom insert 160 of the
gemstone assembly of FIG. 10 or the culet 136 of the gemstone
assembly 11. The bottom insert 160 is employed to lock the gemstone
assembly into the hole provided in the prong assembly 102.
[0044] Referring to FIGS. 12-15, the prong assembly has a hole 164
that is formed at the confluence of a plurality of prong arms of
prong assembly 102. The prong arms have top arm ends 180. The
gemstone assembly 116 has a pavilion 182 that simulates the
pavilion of a large gemstone. The bottom insert 160 of the gemstone
assembly 116 is locked into hole 164 to complete the assembly of
the gemstone setting 100. In order to assemble the gemstone setting
100, the gemstone assembly is 116 is moved along the direction
indicated by the unidirectional arrow A. The prong arms are
preferably angled to match the angle of the pavilion 182 of the
gemstone assembly 116. However, these arms may be adjusted or
widened or bent to accommodate gemstones belonging to a wide
variety of sizes. The locking of the bottom insert 160 into the
prong hole 164 secures the gemstone assembly 116 more firmly. In
gemstone setting where the gemstone assembly has a bottom insert,
the prong assembly base 112 has a space that shows the position of
the bottom insert inside the prong assembly.
[0045] In this particular embodiment, the prong assembly has four
prong arms. However, the number of prong arms may be varied based
upon various design considerations such as, for example, the
gemstone shape being simulated by the gemstone assembly 116.
[0046] The gemstone assembly 112 is constructed in accordance with
the present invention presents not only very clean and neat
simulations of large gemstones, but also adds to the brilliance and
scintillation of the jewelry. The gemstone setting also gives
flexibility to users to use very small inexpensive gemstones to
provide a gemstone assembly that can be made to resemble a variety
of large gemstones of their choosing.
[0047] Referring to FIGS. 15A-15B, a gemstone assembly 186
constructed to simulate the large emerald cut gemstone is
shown.
[0048] Referring to FIGS. 16A-16B, a gemstone assembly 188
constructed to simulate the large gemstone shown. The ratio of
dimensions of the gemstone is set as per the standards recommended
for a particular diamond cut. The length to width ratio is within
the acceptable range for the heart shaped gemstone. The assembly
188 uses micro diamonds between 0.0025 carats to 0.04 carats.
[0049] Referring to FIGS. 17A-17B, a gemstone assembly 190
constructed to simulate the large marquise gemstone is shown. The
length to width ratio is within the acceptable range for the
marquise cut gemstone. The marquise assembly 190 uses micro
diamonds between 0.0025 carats to 0.04 carats.
[0050] Referring to FIGS. 18A-18B, a gemstone assembly 192
constructed to simulate the large square shaped gemstone is shown.
The length to width ratio is within the acceptable range for the
square shaped gemstone. The assembly 192 uses micro diamonds
between 0.0025 carats to 0.04 carats.
[0051] Referring to FIGS. 19A-19B, a gemstone assembly 194
constructed to simulate the large cushion shaped gemstone is shown.
The height of the assembly may be approximately 4.0 millimeter. The
length to width ratio is within the acceptable range for the
cushion cut gemstone. The assembly 192 uses micro diamonds between
0.0025 carats to 0.04 carats.
[0052] Apart from the gemstone shapes discussed above, other shapes
such as the rectangle shape, the princess cut, the trilliant cut
can also be simulated by constructing the gemstone assembly in
accordance with the present invention.
[0053] It is evident from FIGS. 15A-19B that the gemstone
assemblies constructed in accordance with the present invention
have all the important features of any prevalent and popular
gemstone cuts and shapes. Every gemstone assembly has at least a
culet, a table, a crown, a girdle and a pavilion which are the
important parts of a gemstone. The gemstone assembly also maintains
acceptable standards of length to width ratio. The gemstone
assembly tries to achieve the ideal length to width ratio.
