Featured Diamond – The Timeless Pear Shape
The pear-shaped diamond has increased in popularity and we are excited to offer a selection to our qualified customers. These near-colorless diamonds range from 0.5-0.75 per carat and are classic way to add sparkling brilliance to your high-end designs!
Introducing Renaissance™ Lab-Created Diamonds
Popular with younger buyers, Renaissance™ lab-created diamonds are chemically, physically and optically identical to natural diamonds. Use small side stones in popular ring styles, or offer your clients a larger, brighter diamond at their ideal price point!
“When I call for diamonds from Shannon, she knows how fussy I am, especially because I’m a stonecutter. She knows, after all these years—we have the same eye for stones. I have to over-quality my custom-order pieces to ensure I don’t get stuck with the bill.”
—Tim, Customer since 1991
“Rio bends over backwards to find what I ask of them. It was so nice to find a place that was respectful to us. I cannot tell you in words how professional Chris and Shannon are. Their selection is unbelievable—the service and the supply and the resources at Rio are just phenomenal. Anyone looking for a diamond anywhere in the country should go to you, in my opinion. You’re not going to find a better total package anywhere else. I can’t tell you how happy I am. Trust, intelligence and honesty all come together to make it a pleasant experience.”
—Terry, Customer since 2011
