Realistic Book Cover Artwork

I'm in need of a skilled digital artist to create a realistic, object-focused piece for a book cover. The artwork should prominently feature a golden necklace with a pendant made of purple amethyst winged by yellow flourite.

Ideal Skills:
- Proficiency in creating realistic digital artwork
- Experience with designing book covers
- Strong understanding of object-focused compositions

Please provide samples of your previous work that align with this project. Thank you.
