Design 3d crystal for etsy

I have some 3D crystal product images that I want to list on Etsy, but I’d like to make them more attractive. I need help changing the background to something cleaner or more elegant, and I want the products to appear brighter and more eye-catching. The goal is to improve the lighting, sharpness, and overall quality so they stand out better on Etsy. If you can also add a soft glow or reflection effect, that would be a bonus. Let me know if you’ve done similar work before
