Diamond Conversion

Buying a piece of jewelry can be an exciting and sometimes overwhelming experience. To help you make an informed decision, we have put together this diamond and jewelry buying guide with tips and information to help you navigate the process.

Understanding Diamond Sizes

Choosing the perfect diamond can be overwhelming, especially when it comes to understanding the different sizes. At C6 Diamonds, we believe in making this process as seamless and informative as possible. Our comprehensive diamond size chart is designed to help you visualize and compare diamond sizes, ensuring you find the ideal gem for your needs.

Why Diamond Size Matters

The size of a diamond significantly impacts its overall appearance and value. While carat weight is a common measure, the actual dimensions of the diamond play a crucial role in its visual size. A well-proportioned diamond can appear larger and more brilliant, making the size chart an essential tool for your selection process.

How to Use Our Diamond Size Chart

Our diamond size chart provides a clear comparison of diamond sizes in millimeters and carats. Here's how you can use it:

  • 1. Visual Comparison: The chart allows you to compare the actual size of diamonds at a glance.
  • 2. Carat to Millimeter Conversion: Understand how different carat weights translate into actual dimensions.
  • 3. Ideal Proportions: Identify the ideal dimensions for various diamond shapes and cuts.
