Our Team

Cindy Gayer

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 Beringer

Colette is widely known as a confidante to many. Her appreciation for all things beautiful is unmistakable, yet her passion is diamond jewelry. Following a successful career in sales and marketing, particularly in luxury lifestyle publications and interior design, her love for diamonds has now reached its pinnacle.

Renowned for her integrity, munificence, and steadfastness, Colette magnetically attracts individuals from various circles, be it friends, family, or clientele. During intervals away from her family in Cleveland and Chicago, Colette establishes her home in Naples, Florida, alongside her spouse Dave, and their canine companions, Navy and Teddy.

Colette graciously works with clients to discover the diamond jewelry that fits their distinct preferences and lifestyles.
