I’m Sandrine, a GIA-qualified gemologist with over 20 years of experience in global fine gems and jewelry sales, marketing, and product development. I’ve had the privilege of leading and training international teams, creating long-lasting and authentic client experiences that truly convert, and coaching high-potential talent on the sales floor and in leadership roles.

Gems are my language, but people are my purpose. Living and working across five continents broadened my understanding of cultural and human experiences, nurturing my deep belief in our shared humanity and intrinsic sameness. This journey taught me how culture shapes connection and how authentic connection drives performance. That is the core of the SEVEN GEMS METHOD™.

Today, I partner with leaders and sales teams across the jewelry sector and allied training organizations to elevate performance without losing the human touch. Through curated trainings and coaching, I foster ownership, responsibility, joy, and durable momentum.

Beyond coaching, I write features and stories on gems and jewelry history, and I design unique jewelry pieces that reflect my love for materials, craftsmanship, nature and meaningful stories. I’m also deeply committed to the natural world – wildlife, the outdoors, and responsible stewardship inspire me every day.
