Nicole married into the business, and lets just say her husband and pioneers of the business could not have done it without her! She has always been the sales guru, and although he passed years ago, she took everything she learned and has continued to serve the community in Estero going on 14 years. She is the expert when it comes to all things having to do with design, custom work, and repairs. 

Customer Reviews

“Nicole was amazing to work with. Her entire team delivers exceptional customer service. She took my grandmothers’ diamonds and made my design come true. Now I wear my beautiful diamonds everyday instead of them sitting in a jewelry box. Many thanks to she and her team and I highly recommend you pay them a visit.”

"Nicole helped me buy the perfect engagement ring for my (now) wife. She was knowledgeable, informative, charming, and fun! I would recommend her to anyone! She also sold me my wife's ring for a great price! If you are looking for personal, local, and knowledgeable service, then this is the place for you!"

"Nicole is a wonderful designer and person. I love her jewelry, I have to fight with myself to keep from going into the store all the time. When it is the right time to buy jewelry, this is where I go!”
