Meet the diamond lovers.

Cindy@Authentic-Diamonds.com

With a lifelong passion for fashion and art and a successful career in interior design, Cindy Gayer is excited to jumpstart her newest venture — lab grown diamonds. 

The inspiration behind Authentic Diamonds came from her sustainable lifestyle of investing in beautiful and durable pieces you can live, work and play in. You may even see Cindy wearing a tennis bracelet in yoga class or her eternity band on the tennis court.

Cindy has roots in Michigan and New York but for the past twenty years has happily lived in Naples, Florida, where you can find her with her husband Tom and King Charles Spaniel Samantha Lee.

Colette@Authentic-Diamonds.com

In childhood, Colette was drawn to everything beautiful. She loved dressing up and trying on makeup, but above all else, she loved diamonds.

After spending a successful career in sales and marketing, notably for luxury lifestyle magazines and interior design, her adolescent love of diamonds has come full circle. Colette is excited to help you find the gorgeous diamonds she dreamed about as a little girl.

Friends, family and clients of Colette are drawn to her trustworthiness, generosity and dependability. When not with loved ones in Cleveland and Chicago, Colette lives in Naples, Florida with her husband Dave and dogs Navy and Teddy.

At 14, Camille landed her first job as an “intern” at Cindy’s interior design studio, where she got her first taste of a creative career. 

Twelve years later, she went on to study mass media communications and journalism and currently specializes in digital marketing, creating social media content, email newsletters and websites.

Camille proudly wears a lab grown engagement ring from her fiancé Joe and hopes more young couples her age consider the affordable and sustainable gem option.
