Description
Patented May 25, 1937 UNITED STATES PATENT OFFICE GEM Evanda Pollard Haltom, Fort Worth, Tex. Application May 14, 1936, Serial No. 79,795
2 Claims.
My invention relates to a process for treating gem material and to the product thereby produced, and has for its object to produce in gems or stones an increase of lustre or brilliance so that a relatively dull gem or stone will be given a greatly improved appearance and greater value.
With the above object in view my invention consists in and comprises the improved process and product hereinafter described and claimed.
Referring to the drawing:
Figure 1 is a front view on an exaggerated scale of a convex surfaced gem or stone embodying my invention. Y
Figure 2 is a central vertical sectional view of the gem shown in Figure 1, and
Figure 3 is a view of the back of the gem shown in Figures 1 and 2.
The gem or stone to which my process may be applied may be of any usual material either natural precious, or semiprecious gems, or stones produced by synthetic methods or of glass. The gern or stone shown is of a usual shape having its face l convex and its back 2 at.
In this at back 2 I form by grinding or otherwise parallel grooves 3 throughout the surface of the back and then polish the intervening surfaces 4 between the grooves, and I also polish the sides 5 of the grooves which are approximately V-shaped in cross section. I'here is thus produced on the back of the gem or stone a succession of linear faces of which one is a portion of the ilat back surface and the other two are at angles to the at back surface, and also at angles one to the other.
Light rays entering through the face of the stone or gem are reflected by the polished faces of the back and are concentrated toward the producing a lustrous a star sapphire or applied to stones having than convex and having grooves in said flat surface
