Companies from around the world have gathered in Verona, Italy, this week for Marmomacc, the annual international stone exhibition, which is now in its 45th year. And the show floor hasn't disappointed with large displays of innovation.

Long-standing exhibitors such as Italian-based Antolini Luigi once again are attracting visitors with its dazzling showcase of slabs from its Precioustone collection. Additionally, the international stone producer is grabbing the interest of attendees with the introduction of its Natura Collection -- featuring various animal patterns that are etched on stone pieces. 

Another display that is attracting attention on the exhibition floor is Marblelace, which features intricately cut pieces of stone that resemble the look of lace. The pieces in this product line can provide a decorative element in deigns. 

As for colors, purple seems to be a trend. The plum shade offers richness and vibrancy that can lend itself to a one-of-a-kind design. "Purple is a new design color," said Arik Tendler of CaesarStone USA. "We try to lead the pack instead of being behind the pack."

CaesarStone also expresses awareness of the environment and the Green Building movement with its Classico collection that is recycled. Slabs in the collection consist of material that has been reused instead of being left for waste.  

Innovation also continues to shine at Pokarna. The Indian producer of natural stone and quartz products introduced new shades to its Quantra line, a series of engineered quartz surfaces. The new colors replicate the look of onyx and can be backlit. "This is the first time we are able to make onyx-looking quartz," said Gautum Jain, owner of Pokarna. Among the new colors are Contrail -- a shade of soft tan -- and Noctilucent -- a blend of grayish green.

These are just a few of the many new introductions that are being shown at Marmomacc this year. The show will continue until Saturday, October 2.
