RAPAPORT... Gemological Science International (GSI) has appointed Jonathan Tack as executive vice president of business development.

Tack, who has more than 25 years of experience in the luxury-goods sector, will help the gem lab and educational institution expand its reach and form new partnerships, it said Monday. He previously served as vice president of sales for luxury brand Suberi Brothers, revamping the company and launching its e-commerce site. He then founded fine-jewelry brand Proposition Love, where he designed pieces for Cher, Kathy Griffin and Tori Spelling, before leaving to lead sales and marketing at jewelry companies Beauty Gem and SDC Designs.

“Jonathan has successfully guided cross-functional teams while launching products into new markets, developing business strategies for multichannel sales, and fostering lucrative partnerships,” GSI noted. “His professional drive and loyal relationships have brought him great success, which he plans to continue at GSI.”

Tack’s “vast” knowledge of the industry will help the organization achieve continued growth and success, GSI president Debbie Azar added.
