DETAILED DESCRIPTION OF THE INVENTION

[0070] Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the construction and arrangement of parts illustrated in the accompany drawings. The invention is capable of other embodiments, as depicted in figure as described above and of being practiced or carried out in a variety of ways. It is to be understood that the phraseology and terminology employed herein is for the purpose of description and not of limitation.

[0071] The present invention relates to process of cutting and assembling natural diamonds, naturally colored and treated color natural diamonds to form composite diamond with enhance brilliance. The diamonds are precious natural resources which are obtained as a raw diamonds from mines. In general, brilliant diamonds have crown, pavilion, girdle and facets. The brilliance depends on its very bright and smooth surface for reflection in combination with its high refractive index. Diamonds are cut in such a manner that when a viewer is looking at the crown/table, the light entering the diamond through the table/crown is reflected within the diamond by the pavilion's facets and units through facets on the crown or the table for the benefit of the viewer.

[0072] The process of cutting and assembling diamonds to form composite diamond having enhanced brilliance and shade comprises following steps on raw diamonds:

[0073] Assorting the small diamonds from raw diamonds based on clarity and color, each assorted diamonds as per the ultimate design, mapping each blocked diamonds in manner that minimize the waste and optimize the use of maximum diamond.

[0074] The assorting mainly focuses on parameters like size, purity and design etc. The present invention mainly involves forming composite diamond from white, naturally colored and treated color diamonds. The naturally colored and treated color diamonds include pink, yellow, blue green and other color diamonds. In many diamonds, though, color is quite subtle. In addition, colors that result from atomic-level impurities or defects may be evenly or unevenly distributed within the rough crystal. Color can also result from the presence of a colored inclusion(s), or from staining (usually brown) by a foreign material within a surface-reaching fracture. These impurities are removed to manifest the exact color. The color treated diamond refers to the natural diamonds and the diamonds which are processed by radiation treatment to coat the artificial color. Further present invention uses various 8 shades i.e. faint, very light, light, fancy light, fancy, fancy intense, fancy deep, fancy vivid in the diamond for creating variety in the diamonds. The process of assortment is also focused on the purity or clarity of raw diamonds where rough diamonds are sorted in terms of their potential clarity grade. As with color grades, the better clarity grades are only distinguished by slight differences, such as in the number, visibility, position, and size of internal features (inclusions, fractures etc.), as these features would appear in the final faceted diamonds. The process of blocking involves positioning each assorted diamonds for the process of mapping the diamonds. The process of blocking is important because the same is crucial for ultimate brilliance, shade and size. The blocking involves the process of separating diamonds from the assorted diamonds with respect to purity and proposed design. The blocks are established based on proposed design and number of pieces intended to form as combinative purpose. These blocks are prepared via horizontally mounted circular cast iron disc known as scaife of the blocking machine.

[0075] The process of mapping involves magnification of each blocked diamond in the machine to have cut of the design. The process of mapping will figure out the best possible shapes of the diamond in order to minimize waste and maximize the yield of the rough diamonds. The process of mapping also focused on various defects in the raw diamonds i.e. flawless, internally flawless, very slightly included that changes design for more perfect shape.

[0076] The process of cutting is performed on laser machine. The process of cutting in the present invention does not refer only to a diamond's shape but to a diamond's proportions, symmetry and polish. The present invention provides wide range of combinations that are possible, ultimately determining the diamond's interaction with light. In general when light strikes a diamond, approximately 20% immediately reflects off the surface (as glare) and 80% of remaining that enters, a portion will escape through the bottom of the diamond (where the observer cannot appreciate it). The present invention will proportion diamond that have each facet properly placed and angled so as to maximize the amount of light that reflects back out of the crown (top) of the diamond, to the eye of the observer.

[0077] The present invention provides combinative principle in small brilliant cut diamonds that assembled to have overall brilliance through cumulative reflection and refraction in system. Each diamond is cut to have three main portions i.e. a crown (Cw), a girdle (G) and a pavilion (P) in which the girdle (G) is the widest portion around the diamond forming a thin circle. When viewed from a side, the girdle (G) is in form of a line, i.e. a girdle line. The crown (Cw) is a trapezoid portion above the girdle (G), while the pavilion (P) is a triangle portion below the girdle (G).

[0078] The pavilion of diamond of the subject invention is cut to have at least three main facets (A) angularly pointed toward periphery, at least three secondary facets (B1, B2) between two main facets (A) and at least one tertiary facet (C) on at least one of periphery. The secondary facets (B1, B2) are either angularly pointed toward the main facets (A) or toward the periphery. The main facets of the pavilion (P) of the diamond are cut within the angle degree of 25 to 30. The secondary facets (B1,B2) of the pavilion (P) of the diamond are cut within the angle degree of 27 to 32. The tertiary facet (C) of the pavilion (P) of the diamond is cut within the angle degree of 55 to 60.

[0079] The crown (Cw) of diamond of the subject invention is cut to have flat facet (T) and at least one main facet (D) on at least one of periphery. In another embodiment the crown (Cw) of diamond of the subject invention is cut to have flat facet (T), at least one main facets (D) having at least one angle in contact with the flat facet (T), two secondary facets (E) between the flat facet (T) and at least one tertiary facet (F) and on the periphery. The main facets (D) of the crown (Cw) of the diamond are cut within the angle degree of 28 to 31. The secondary facets (E) of the crown (Cw) of the diamond are cut within the angle degree of 20 to 25. The tertiary facets (F) of the crown (Cw) of the diamond are cut within the angle degree of 32 to 35.

[0080] The crown (Cw) height, pavilion (P) height and girdle (G) thickness of each diamond to form the composite diamond ranges from 5 to 8%, 40 to 45% and 10 to 15%. The L/W ratio and total depth of each diamond varies considering crown (Cw) height, pavilion (P) height and girdle (G) thickness due to change in design.

[0081] The step of polishing is done by setting the diamonds in a mechanical clamp also known as tang and holding it down on a revolving cast-iron lap (horizontal, circular disk) also known as scaife of the machine, that has been charged with diamond dust. Further, the present invention focuses on individual diamonds polishing where facets of adjacent diamonds are sharing at least one side of the diamonds therefore the polishing of the said side is performed at the same grade as precedent diamonds grade. The polishing of the flat surface is done with the care of refracting angle and refractive index consideration. The step of polishing includes the formation of girdle (G), overall proportions, such as table size, crown (Cw) angle, pavilion (P) depth percentage and facets for each piece which shares the same with adjacent piece.

[0082] The step of grooving is done by the mounting the polished diamond pieces together as per the design of the jewelry.

[0083] The basic principle and the step of arranging diamonds to form composite diamond of the present invention is described in FIG. 1 where it is observed that cumulative reflection and refraction in two diamonds if they placed in specific arrangement i.e. the diamond having at least one straight edges girdle (G) is placed together. At least three diamonds are held adjacent to each other along a respective single straight edge of the girdle (G) of the diamonds.

[0084] In another embodiment, the diamond having at least one straight edges girdle (G) and at least one tertiary facet (C) of the pavilion is placed together.

[0085] The composite diamond according to the present invention includes but not limited to shapes or combination thereof i.e. heart, pear, flower, radiant, rectangular, round, marquise and star. FIG. 2-52 describes different shapes of the composite diamond prepared from different number of individual diamonds. In these figures number of diamond is sequentially mentioned.

[0086] The composite diamond according to the present invention when a viewer is looking at the crown, the light entering the diamond through the crown is reflected within various diamonds by the flat adjacent surfaces i.e. united through girdles (G) in a manner that ultimately reflected out from the crown (Cw) as the enhanced brilliance for the benefit of the viewer. The brilliance is enhanced through preventing loss of light, in combinative system the factors like refractive index, number of refraction, angle of refraction and arrangement of closely packed diamond system. The refractive angle of the diamond is 22 to 24 and the same is important to prevent loss of light and brilliance enhancement.

[0087] The adhering is important as ultimate brilliance and diamonds setting is governed by successful mounting of pieces on metal wire or other abstracts. The metal used for the purpose of adhering mainly includes but not limited to gold and platinum. This binding is also made by the metal wire duly fixed in the groove made in the girdle (G). In addition, adhering of diamonds is performed via chemical treatment and subsequent washing. In other embodiment setting of a center diamonds held by small prongs, an outer series of diamonds wherein each outer diamonds is held by a pair of large prongs, and an intermediate series of diamonds held by the larger outer prongs which hold the small diamonds so that the intermediate diamonds partially cover the center diamonds and outer series of diamonds in a manner which conceals the way the outer diamonds are held.

[0088] Once the composite diamond is prepared if it required it is buffed.

[0089] After that the final jewelry is evaluated in for combinative effects of the facet shapes and angles, girdle (G) width, culet size, polish and symmetry on the overall appearance of a diamond.

[0090] The invention is illustrated more in details in the following example. The example describes and demonstrates embodiments within the scope of the present invention. This example is given solely for the purpose of illustration and is not to be construed as limitations of the present invention, as many variations and other designs thereof are possible without departing from spirit and scope. Different shapes of the composite diamonds using the present invention is prepared by following example.
