 2020 Worldwide Tumbling Contest!

The Feather River Lapidary & Mineral Society, Inc. would like to congratulate the top 3 winners of our contest.

1st place winner: JOSEPH BLANCHARD OF IL.

2nd place winner: Bob Davis of M.I.

3rd place winner: Chuck Martin of MI.

I want to first thank all the contestants for being so patient with us. 2020 has been a tough year for many of us, especially with the Northern California fires once again. Four of the five judges were forced out of their homes while in the middle of judging the stones. Some were out of their house for 20 days! Luckily they are all back in their homes and the stones made it back to me safely. No photos yet of the stones. 

I would like to thank the five judges for this year’s contest: Tom, Suzy, Bruce, Carol and Jesse. Awesome job!

There were only 3 points difference between the top 3 winners. Following is the point system we use to judge your work. Points are 1 (poor) to 5 (excellent) for a total of 30 points. What we judge on is 1-Finish, 2-Chips, 3-Polish, 4-Grinding marks, and 5-Overall appearance. We then add all five judges' scores for the total points of 150.

Joseph was our first contestant that scored 5 points across the board for a total of 150 points. Bob scored 148 points and Chuck scored 147. Very close contest this year. Great job to the three of you! The remaining 24 entries ranged in points from 143 to 87.

We hope that you will join in the 2021 contest starting January 1. Cost will once again be $35.00. The stone will be Burris Creek Jasper. Due to Covid-19 our travelling has been limited greatly this year. We hope that you are staying safe and healthy in these trying times. Now go out and brag about your accomplishments with the tumbling contest this year. You all deserve it!
