Diamond Miner Trophy in Bejeweled 3

In Diamond Mine you need to match gems that are against the ground to destroy it and unlock gold etc. Be aware that horizontal matches will destroy 3 or more spaces on the ground while vertical matches only destroy one. Focus on horizontal matches.

In order to reach 200m you need to essentially get to level 10 of Diamond Mine. There is a line on the grid and you need to destroy all of the rock below that line to progress the level and get additional time. Each time you destroy all of the rock below the line you’ll dig 20m more down.
