• Use masking and selection tools to isolate the jewelry pieces from the background. This allows you to edit them separately for best results.
• Adjust brightness, contrast, shadows and highlights to make details stand out. Increase contrast slightly to accentuate jewelry lines and textures.
• Carefully sharpen jewelry details and edges but avoid over-sharpening. A high pass filter can help sharpen without excessive grain.
• For colored gemstones, boost vibrance and saturation subtly to make the colors pop without looking artificial.
• Remove any visible dust, scratches or imperfections through spot healing and cloning if needed.
• Add catchlights to gemstones and metallic parts by using a brush tool set to screen mode. This makes them shine.
• Give metal components a polished look by applying the Smudge Tool lightly for a soft sheen.
• Use dodge and burn techniques to better define contours and light reflections on rounded jewelry shapes.
• Apply noise reduction selectively to smooth out any unwanted rough texture while retaining key details.
