Understanding Diamond Carat Size

Carat weight is probably one of the most critical things to consider when choosing a diamond for any of your pieces of jewelry. Carat weight refers to the weight, not the size, of the diamond. Two diamonds with the same carat weight can be different sizes based on their shape and cut. Here's a brief rundown:

2 Carat Diamond Ring

Measuring about 8.0mm in diameter. This is a more dramatic look without going overboard, which makes it ideal for those who want something showy without giving up on the subtleness.

3 Carat Diamond Ring

Approximately 9.3mm in diameter. This size is best for those who want to go big on the sparkle. This size is best for those who want to go big on the shine. It is mostly selected for special/fancy events or to celebrate a big milestone.

Common Mistakes to Avoid

1. Choosing based solely on carat weight without considering cut, clarity and color. As cut and clarity is an important aspect of the diamond and plays a huge role in what it looks like.

• Excellent Cut: Reflects maximum light, making the diamond appear larger.
• Poor Cut: It diminishes sparkle and can make the stone look smaller.
• Clarity: Measures inclusions and imperfections.
• Color: Ranges from colorless (D-F) to light yellow or brown (Z).
  

2. Ignoring lifestyle factors—larger diamonds may not suit everyone’s daily routine.

3. Overlooking how different shapes affect visual size.
