OVAL DIAMOND SIZE CHART
Choosing the ideal oval diamond can feel overwhelming. Unlike round diamonds, ovals introduce a new factor: proportions. They appear larger and more flattering on your finger than rounds of the same weight. But with many size variations, how do you find the one that sparkles and complements your style? In this guide, we reveal the secrets of the oval diamond size chart. We'll translate carat weight into millimeter measurements and share the magic ratio for maximum brilliance. Get ready to discover an oval diamond that stuns, flatters, and fits your budget perfectly.
