Glasses for Diamond Face Shape: Compare Brow Emphasis, Curves, and Fit

Diamond-face guides agree on drawing attention upward, but differ on whether to use curves, a strong browline, or a nearly invisible rim.

Short answer first

Compare cat-eye, oval, round, browline, and rimless glasses. Every named style below has its own table row; cheekbone width and bridge comfort still need an actual fitting.

Where the sources differ: Warby Parker emphasizes the browline; All About Vision includes oval and browline routes; Mayo names straight or round frames; Evans & Piggott includes rimless frames. The table preserves those distinct recommendations.

How the measurements were added

Named-model dimensions come from the linked brand product pages. Browline and rimless remain “Not stated” because the cited guidance sources do not name product models with measurement fields.

Honesty note. Frame-shape advice is a starting point, not a comfort test. Use a frame’s three printed measurements and try the bridge and temples on your face.
