First and Foremost…the complete line of “Pearl’s” conform with the USGA Rules of Golf. The putter was found to conform on May 20, 1998, and the woods on December 1, 1998.  USGA LETTERS 

Although USGA approval is not a prerequisite to the manufacturing and sale of golf clubs, it is a key factor in determining the acceptability of a golf club for use in any USGA, PGA, Senior PGA, or LPGA sponsored events.
 
The “Pearl” is radically different from anything on the market…Why? Not wood, metal or titanium, but a time-tested, proprietary composite, white in color, injection-molded from custom-designed molds, and with performance characteristics not unlike the old woods made of Persimmon.

The sound of Persimmon…the control of Persimmon… the distance of Titanium!
