The Lone Star Cut, designed by brothers Dr. Paul W. Worden, Jr. and Gary B. Worden, became the official state gemstone cut of the State of Texas when Governor Dolph Briscoe signed House Concurrent Resolution No. 97 on May 25, 1977.
If you guessed that Texas is the only state with an official gemstone cut, you would be right!
The Lone Star Cut is often applied to Texas' official state gem.
H.C.R. No. 97
HOUSE CONCURRENT RESOLUTION
WHEREAS, The flag of Texas, the public symbol for all to see, has a lone star as its prominent feature; and
WHEREAS, This is reflected in the State slogan "Texas--The Lone Star State"; and
WHEREAS, A special gemstone cut known as the Lone Star Cut has been designed by two native Texans; and
WHEREAS, Any gemstone may be cut in this manner, including the State Gem, the Blue Topaz; and
WHEREAS, The special characteristic of the Lone Star Cut is the appearance to the viewer when looking directly into the stone, in that it reflects the five-pointed star; now, therefore, be it
RESOLVED, by the House of Representatives of the State of Texas, the Senate concurring, That the Lone Star Cut be and is hereby designated as the official State Gemstone Cut of Texas; and, now, be it
RESOLVED, That the specifications for faceting the Lone Star Cut are for an 80 index gear and shall be as follows:
1. Cut 10 facets at 45°. Index 4-12-20-28-36-44-52-60-68-76.
2. Cut 5 facets at 54°, until the star is a measured 65 percent of the diameter of the stone. Index 80-16-32-48-64.
3. Cut 10 facets at 60.7°. Index 2-14-18-30-34-46-50-62-66-78. These are to meet the points of the star exactly.
4. Cut 5 facets at 65°. Index 8-24-40-56-72. These should also meet the points of the star exactly.
5. Prepolish in the same order, then polish from the culet to the girdle.
1. Cut 10 facets at 41.5° Index 2-14-18-30-34-46-50-62-66-78. These should be cut until the girdle is of the proper thickness.
2. Cut 5 facets at 52.1°. Index 8-24-40-56-72. Cut these until they match the corresponding facets of the pavilion in width at the girdle. This will insure the proper size for the table.
3. Cut 5 facets at 30°. Index 80-16-32-48-64.
4. Cut the table at 0° until the 30° facets meet at a point.
5. Prepolish in the same order, then polish in reverse order. If desired, the table may be cut and polished last; it depends on your machine. The girdle may be polished or not, as you wish.

Only a few of Texas' myriad symbols were actually adopted by an act of the legislature and written into the Texas Statutes.
