Why jaw width makes this a good match
A diamond face has cheekbones that form its widest line, with a narrower forehead and jaw. The chin is pointed. A full beard suits this face shape because it can fill out the narrow lower face.
Where you place that fullness matters. Width at the forehead and chin softens the cheekbones' point, while volume at cheekbone level exaggerates it. Your beard shapes the lower part of that outline.

Keep the chin short and the sides fuller
Shape it: keep the chin short and the sides fuller. Ask your barber to preserve width beside the jaw while limiting length at the chin.
A diamond-shaped face with a full beard doesn't need a longer point at the bottom. If your chin already looks long or pointed, extra length there carries that line farther down. Keep the fullness across the lower face instead of concentrating it at the tip.
Set the lines while the beard grows
Don't wait for a finished beard before deciding its outline. The common mistake is growing everything first and shaping it later. Set the cheek and neck lines from week two.
Use those lines to guide the beard as it grows. Keep the intended shape in mind: fuller sides and a shorter chin. Letting the chin grow unchecked works against the reason this style suits a narrow jaw.
Keep up with the shape
Upkeep means shaping every two to three weeks and daily combing. At each shaping appointment, check whether the sides still provide width and the chin has started to look longer.
