3D Product Animation for Jewelry

I am looking to animate a 3D jewelry product in a cartoon/animated style with a gold/silver tone color palette. The product is 7 individual pendants. I need the animation to be eye-catching, attention-grabbing, and creative. I anticipate the animation to be around 15-30 seconds in length. Please provide examples of your past work on similar projects when you apply. The product must be of high quality and accurately represent my product. Please explain how you think you can best create this animation to capture my vision.
