     Catalyst' vision is to empower people to become that spark of change in the world through the jewelry they wear. By choosing Catalyst for everything jewelry, they join the movement of ethical and socially conscious fashion.

     In 2011, Steven Hartono founded the company to become a catalyst in the jewelry industry and in the world. Steven learned production from working closely with a GIA graduate, jewelry design from attending countless trade shows and following trends. He also leads the business development, having learned the ropes from being in corporate management and has a double degree from UCLA. He takes joy in customer service and educating clients about his Los Angeles made - engagement, bridal and fashion jewelry and enjoys donating a portion of the profits to a cause - such as ending human trafficking.
