ABOUT US

Several years ago, the Diadem founders set out to change the game - to create a product that could generate unfathomable spin with a comfortable feel. 


Players no longer have to sacrifice their body (shoulder, elbow, wrist) to achieve the spin they crave and be able to maintain the utmost precision and control on their shots. After testing an array of different shapes (round, hexagon, octagon, twisted) and gauges of string to find the most performance-enhancing string, came the birth of the patent pending string aka Star Core Technology. 


After multiple generations of prototyping and adjusting everything from formulas, degree of angles, sharpness and extrusion process, the Solstice line of products was created - Solstice Power and Solstice Pro. Since its introduction, the Elite XT range has been added aimed at bigger hitters, those looking for massive spin without compromising durability.​ 


 As former junior, college and professional tennis players, Diadem look forward to sharing their passion of the game with tennis enthusiasts.​
