To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This was a birthday gift for a six year old who loves rocks, minerals and gems. Very clear photos and useful tables at the end. This is a book that will interest the child as they get older. The book was a big hit!
Very beautifully done. Good information. My seven year old granddaughter received it for her January birthday and loved it as she is fascinated by rocks and gemstones and started collecting at the age of 2. The colours are captivating. Thank you so much.
