Comercianti de Diamante by Rosenberg was born out of the passion for precious gemstones and jewels, combined with the founder's experience working with the top jewelers of Bucharest. In 2007, Alex took over the leadership of Cielo Venezia 1270, the second jewelry company founded in Italy.

  After, he franchised two stores, built relationships with over 40 retailers across the country and opened 10 stores within the company. This experience has led Alex to fall in love with this business, deciding to take on a diamond business of his own, Rosenberg & Associates, who have now become Comercianti de Diamante by Rosenberg.

  Our purpose is to create bespoke jewelry for customers who are paying attention to details and constantly search for exclusive products through an expert gemological assistance service. In addition to guaranteeing exclusive brands and free gem consultancy, we offer an excellent service in the creation of unique jewelry, alongside masters of jewelers.

  Our workshop specializes in creating and making unique jewelry of any shape, color, and desire. Being a GIA* retailer, we care about sustainability. All our diamonds are ethically sourced and certified.

  This means our gemstones come from countries where they were legally extracted. Attention to details and originality in creation is our emblem. We draw, design, and craft any of your ideal jewelry.
