History 
A leader in its sector, GSM was founded in Carpi in the early ‘90s by Giuliano Rossi and his sons Massimiliano and Stefano, who doggedly wanted to specialise in the manufacture of automatic machines for the application of hot fix rhinestone, crystals and cabochons. 
Our goal was to cater to the market demand for distribution of crystals to be used in the creation of fashion garments and accessories. 
Thanks to our dedication, seeking perfection and innovation, the GSM crystals and strass are now used in various sectors from clothing, shoes,fashion accessories to jewellery and furnishing. 
Chosen by big names in the fashion system because of their superb quality, these perfect crystals adorn exquisite objects of desire all over the world. GSM offers the best in system design and construction for the sector industries.  

Technology and Machines 
Continuously developing technology, curiosity and acuteness characterise the work of GSM, which debuted in 1996 with the world preview of Fixy 2400 Twin Head: the first automatic machine with dual loader for the application of hot fix rhinestones. Since then the GSM innovation process has not stopped resulting in the design of Fixy 2400 Twin Head Ultrasonic: the machine with all the features of the earlier model and in addition an exclusive ultrasonic soldering system. The last-born of the family is Fixy Automatic capable of producing any pattern directly on the support, fabric or leather, without using preconfigured guides. 

Brilliant Binomial with Preciosa
Not wanting to settle for second-best and wanting to achieve top product quality, GSM many years ago tied a fertile knot with Preciosa, in its turn a world leader in the creation of high-quality crystal. 
Born in the heart of the earth, in the air and, for some decades now in laboratories, crystals have always been admired for their beauty and used as ornaments in cultures across the world and have today also become an essential part of technology. 
Crystals have a life of their own: they are born, grow, sometimes change and die. In the Preciosa laboratories today the growth of a crystal can be controlled with an accuracy unachievable in nature. The partnership with Preciosa allows creating an exceptionally specialised product. 
GSM and Preciosa guarantee crystals for specific sectors and provide support services dedicated to anticipating the trend and the application technologies.
