How to use this Diamond Size Charts template
Can these charts help distinguish between diamond cuts with similar carat weights but different sizes?
Yes, these charts display both carat weights and millimeter measurements for popular cuts like round brilliant, princess, and oval. For example, a 1.00-carat round diamond might measure 6.5mm, while a 1.00-carat emerald cut could be 7.0mm long but narrower in width. This helps buyers see how shape affects perceived size.
Are these charts designed for specific diamond shapes, or do they cover a broad range?
The collection includes charts for round, princess, oval, emerald, marquise, and pear cuts, with millimeter measurements and actual-size visuals for each. Some charts focus on a single shape (like round or princess), while others compare multiple shapes in one chart for quick reference. This variety helps jewelers and buyers find the exact comparison they need.
How do the visuals on these charts compare to real diamonds, and are they to scale?
The charts include actual-size visuals printed at 100% scale, so a 6.5mm diamond will appear exactly 6.5mm wide when printed. This lets users hold the chart up to a diamond or its setting to see how it measures in real life. The visuals are simplified for clarity but maintain proportional accuracy to carat weight and millimeter data.
