About me, the owner of Radiant Reef Jewels

My name is Siena Ciliento, I was born, raised, and live in Clearwater, Florida. I am the founder of a non-profit, Marine conservation, company- Radiant Reef Jewels.

In my free time, you will almost always find me near the sea. With the ocean practically in my backyard, it has always been a part of me. I have seen Florida’s Gulf Coast through both its best and worst times, which has shown me just how important and fragile this ecosystem can be. As a teenager growing up in such a special place, I feel a responsibility to help protect it however I can. It is a blessing to call the Gulf Coast my home, and I want to do my part to keep its waters clean and its marine life healthy. That is why I combined my love for jewelry, design, and the Gulf into my business, Radiant Reef Jewels. Through my jewelry, I hope to give back to the place that has given me so much.

Each time $1,000 in necklaces is made, the money is donated to various marine conservation companies who then make a difference by carrying out Florida clean water acts, animal rehabilitation, and sea life protection.

Events

Radiant Reef Jewlels Pop-Up Events

The Edit Boutique Pop-Up Sale

Radiant Reef Jewels hosted a pop-up event at The Edit Boutique in Belleair, bringing together members of the local community to shop for a cause. The event had an incredible turnout, with friends, families, and neighbors stopping by to support our mission and shop our handmade jewelry. By the end of the event, we raised $1,000, which was donated to Captains for Clean Water to support their work protecting and restoring Florida's waterways. This event was more than just a pop-up... it showed me how a community can come together to make a real difference for the waters we all call home. https://captainsforcleanwater.org @captainsforcleanwater -Instagram @the_edit_ boutique_ -Instagram

Safety Harbor Third Friday 7/17/ 2026

Safety Harbor Third Friday was such a fun opportunity for me to take Radiant Reef Jewels to one of the area's biggest community events. I loved setting up alongside so many different local vendors and meeting people throughout the night who shared my love for Florida and its wildlife. The energy of the market made it an experience I will always remember. Most importantly, the event allowed me to donate $1,000 to FWC (Florida Fish and Wildlife Conservation Commission) , helping contribute to the conservation of the wildlife and natural habitats that make Florida so special. https://myfwc.com https://www.facebook.com/3rdFridaySafetyHarbor/

Clearwater Marine Aquarium has always been a special place to me. Having spent so much time volunteering there I have seen firsthand the dedication that goes into protecting and caring for marine life. At Designer Bag Bingo, I had my own Radiant Reef Jewels table set up inside the bingo room, displaying a variety of my necklaces and jewelry for the hundreds of women attending the event. Throughout the night, I was able to meet so many new people, share the story behind Radiant Reef Jewels, and explain how my jewelry connects to my passion for the ocean. The room was filled with excitement as guests played bingo, won designer bags and prizes, and supported the Aquarium. Having my business be part of an event benefiting an organization I already love and volunteer with made the experience even more meaningful. At the event, I made $1,000 that was donated to Clearwater Marine Aquarium to help support its mission and the marine animals it works to protect. https://www.cmaquarium.org @cmaquarium -Instagram

Features

The Stroll Belleair & The Beaches magazine was kind enough to feature Radiant Reef Jewels in their September magazine issue. The four magazine pages were so thoughtfully designed and display the origin and impact Radiant Reef is making so well!
