Gemstone Setting Arrangement and Method for Setting a Gemstone
Disclosed is a gemstone setting arrangement in which a gemstone includes a groove disposed proximal a culet of the gemstone. The gemstone setting arrangement further includes a setting having a culet seating portion and a girdle retaining portion. A setting abutting portion of the groove engages a gemstone abutting portion of the culet seating portion. Translation and rotation of the gemstone relative to the setting are inhibited. Also disclosed is a method for setting a gemstone.
This invention is in the field of jewelry design and manufacture, and in preferred embodiments is in the field of setting of gemstones, such as natural and synthetic diamonds and other gemstones.
BACKGROUND OF THE INVENTION Gemstone jewelry comprises at least one gemstone retained in a setting, the combination being known as a setting arrangement. Numerous gemstone setting arrangements are known in the art. Conventionally, a so-called “solitaire” setting arrangement includes a base and a plurality of protruding gemstone retaining prongs extending therefrom, the prongs forming a retainer or “cage” for a gemstone. The setting is typically made from one or more metals, such as gold, silver, or platinum. Another conventional form of gemstone setting arrangement is known as a “channel set” arrangement. The general form of such arrangement is illustrated generally in
Another prior art arrangement, known colloquially as an “invisible setting” arrangement, is shown in
Many other settings arrangements and methods for setting a gemstone have been heretofore described. Examples of such heretofore described settings and methods can be found in U.S. Pat. No. 5,848,539 (Ouzounian, assignor to Gem Information Center, Inc.); U.S. Pat. No. 5,419,159 (Muller); U.S. Pat. No. 6,584,804 (Freedman, et al., assignor to Volare, LLC); and U.S. Pat. No. 6,782,715 (Ruth), among many others.
The invention seeks to provide, in its preferred embodiments, a gemstone setting arrangement that is different from the heretofore described conventional “solitaire” and “channel-set” arrangements.
THE INVENTIONThe invention provides a gemstone setting arrangement and methods for setting a gemstone, as defined by the appended claims. In preferred embodiments, the gemstone setting arrangement includes a gemstone having, inter alia, a girdle portion and culet. In accordance with the invention, the gemstone is retained by a setting. The gemstone includes a groove that is disposed relatively proximal to the culet of the gemstone and that engages a gemstone abutting portion of a culet seating portion of the setting. The setting also includes a girdle retaining portion that engages the gemstone relatively proximal to the girdle. Preferably, the girdle retaining portion is disposed in an opposed position with respect to the gemstone abutting portion.
A method for setting a gemstone is also provided. The method comprises providing a gemstone and a setting and securing the gemstone with respect to the setting, the gemstone including a groove proximal the culet.
Further details concerning the preferred embodiments of the invention are set hereinbelow and in the drawings and appended claims.
BRIEF DESCRIPTION OF THE DRAWINGS
The terms “top,” “front,” and other terms signifying direction or orientation are not intended to be limiting, but are used with reference to the orientation of the setting arrangement illustrated in the figures. In practice, the arrangement may be orientated omnidirectionally, and plural gemstones may be set in different orientations in a single piece of jewelry. The dimensions shown on the Figures are not necessarily intended to represent actual or relative dimensions. In practice the absolute and relative sizes of the gemstone and setting may differ from those shown.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSThe invention is described with respect to a natural diamond, but it should be understood that the teachings of the present invention are not limited thereto, and that any gemstone setting arrangement may be prepared in accordance with the invention. For instance, the invention may be employed in connection with rubies, sapphires, synthetic diamonds, or other suitable precious or semiprecious gemstones. Likewise, the invention is depicted herewith with respect to a Round Brilliant Cut 58-facet diamond, but it should be understood that diamonds or other gemstones of any suitable shape, regardless of number of facets, may be incorporated into the present invention.
With reference to
With reference to
As illustrated in

With reference to
With further reference to
When a diamond set in a setting as heretofore described, the engagement of the gemstone abutting portion and setting abutting portion inhibits rotation of the diamond about rotational axis 55 (illustrated in
Additionally, with reference to
To prepare an arrangement as described hereinabove, a diamond having a groove as shown in
In an optional part of the invented method, the invention may encompass cutting a faceted gemstone to incorporate the groove as illustrated. Generally, the gemstone should be cut using a conventional jewelers' diamond cutting wheel, which is brought into contact by moving the diamond with respect to the wheel parallel to axis 55 of the diamond, and optionally moving the diamond with respect to the wheel transversely parallel to axis 56 to provide a groove with a uniform wall dimension.
Other embodiments are possible. For instance, the gemstone may be imparted with plural grooves.
When the foregoing teachings are followed, it is possible to prepare articles of jewelry that differ in appearance from conventional solitaire and channel set-arrangements. For instance, with respect to
It is thus seen that the invention provides a setting arrangement that differs from conventional solitaire and channel set arrangements and from conventional invisible setting arrangements.
All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided herein, is intended to illuminate the invention and does not pose a limitation on the scope of the invention unless otherwise claimed. No language in the specification should be construed as indicating any non-claimed element as essential to the practice of the invention. This invention includes all modifications and equivalents of the subject matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.
