How can I achieve high-quality jewelry photography using a macro lens?

To achieve high-quality jewelry photography with a macro lens, start by using a sturdy tripod to eliminate any camera shake. Set your aperture around f/8 to f/11 for sharp focus and good depth of field. Use diffused lighting to reduce harsh reflections and bring out the sparkle. Keep your jewelry clean and dust-free before shooting. Finally, fine-tune colors and clarity during post-processing for a polished finish.
