When you want diamonds, you want I W Marks. The largest independent jeweler in Houston, this family-run business generates more than $10 million a year in sales. But while great service and an unbeatable selection earned I W Marks our Best Jewelry Store nod, the company's also high on our list of socially responsible corporations. In addition to selling jewelry (which it does really well), I W Marks supports the community with generous contributions to the Houston Grand Opera, Houston Symphony and Houston Ballet, as well as the Ensemble Theatre and Society for the Performing Arts. Sell a great product, good for you. Invest those profits in the community, good for us.
