Quick Answer
GemBrush is a precision retouching tool built into the GemIQ mobile app. It gives you three targeted brushes: Remove Blemish, Brighten, and Darken, each designed to make small, controlled corrections directly on your jewelry image without needing a separate editing app.
How to Access GemBrush
Tap the ellipsis (⋯) in the bottom right corner of any image and tap Edit Image. At the bottom of the editing screen, swipe right through the tool options and tap GemBrush. Use the slider to set your brush radius before you start. A smaller radius works best for fine detail like prong work or small stones, while a larger radius suits broader areas like metal surfaces.
Remove Blemish
Use this tool to remove small spots, dust marks, or light artifacts that appear on the jewelry or background. These can come from light reflections, small imperfections on the piece itself, or particles on the shooting surface.
To use it: tap on Remove Blemish and tap on the area you want to fix. Do not drag the brush. Keep tapping on the same spot repeatedly and the tool will gradually blend it into the surrounding area for a natural result.
Brighten
Use this tool to add a soft highlight or to lift areas of the image that came out too dark. This is useful for reclaiming detail in shadowed areas of the jewelry, such as the underside of a ring or the inside of a setting.
