Award-Winning Idea from the CEO Kids Academy Business Contest  
"Learn While You Play! Mineral Playing Cards" 

In November 2020, I participated in a business contest for elementary and middle school students. I proposed the idea for “Calling All Stone Lovers! Multilingual Mineral Playing Cards — Become a Stone Expert!” and won first place.  

Back then, I was a 6th grader who absolutely loved minerals. Because I loved stones so much and couldn’t find anything like it anywhere, I decided to create my own
"Playing Cards That Teach You About Minerals!" 

How to Play with the Mineral Playing Cards

These cards feature photos of minerals I’ve collected, along with information about their hardness, specific gravity, rarity, and unique characteristics.  
I personally researched and wrote all the data because I’m a huge mineral fan! 

1. Play classic card games  
2. Battle it out by comparing mineral hardness, specific gravity, and rarity  
3. Use the cards as mini specimens by displaying them in card holders

To learn how to play the game of Mineral Playing Cards, please watch the video here or visit the "How to Play" page.  

- Instructions for the battle game are included with your purchase!  
- The back of each card features a QR code linking to a detailed mineral encyclopedia website.
