How to Take Better Gemstone Photos
Better photos mean stronger gemstone matches
Do This
Use Natural Light
Shoot near a window or outdoors. Natural light preserves true gemstone color and transparency.
Capture Multiple Angles
Include face-up and side angles to capture cut style, shape, and luster.
Use Neutral Background
Place the stone on white or gray so color and transparency are easier to evaluate.
Avoid This
Avoid Glare and Reflections
Strong reflections hide inclusions and facet details that help with matching.
Avoid Flash
Flash can blow out highlights and hide inclusions or internal texture.
Avoid Filters
Color filters and heavy edits distort hue and clarity, reducing match quality.
