How to Choose A Diamond Engagement Ring

An engagement ring is a beautiful expression of your love for one another. As a timeless symbol of your commitment, it’s important to choose a quality diamond or colored gemstone that will be as enduring as your life’s journey together.

At Classic Rock, we’ve been helping individuals learn about diamonds and colored gems for more than 40 years. Feel free to make an appointment with our knowlegeable staff and GIA Graduate Gemologist. We’ll show you the science behind the gemstones and explain what makes them valuable in one of our four gemological laboratory areas. You’ll learn about the 6 Cs—Color, Clarity, Cut, Carat weight, Certificate and Cost. And discover the importance of proportions—for example, depth and table percentages—to ensure you’re getting the highest brilliancy of your diamond.

We’ll help you find your diamond or colored gemstone, plus the wedding ring design that’s right for you.
