A few years ago, in a very far away place, traveler Mar Aldeguer fell in love with quartz, mother of pearl and coral for their extraordinary beauty, energy and history. And since when you love something, you want everyone to know it, Mar wanted to design fine handcrafted jewelry, with natural stones, that was accessible to everyone. But no one had done this before.

Popular culture and many jewelers called these stones "semi-precious" and Mar always came to their defense, arguing that there was nothing "semi" about them, since for her they were always precious. They were times of uncertainty where the big brands opted for small jewelry, with hardly any stones, that timidly adorned women; but Mar had created COOLOOK and designed jewelry with a wide variety of stones in all their sizes, where apatites, calcites, fluorites, opals... showed off their maximum splendor and energy, elevating the look of each woman's style.

Little by little, COOLOOK jewelry fell in love with the entire world for its charm and versatility, occupying a place of honor within the jewelry boxes of the most influential personalities. And that's how this love story with stones found a mine, and no one will be able to imagine COOLOOK without them.
