The only way for us to get these right now that iknow are.
1. from the character growth reward(your first character to get to X lvl, think maybe 50)
2. Valencia main quest 2 Concetrated Armor stone's and 1 Concentrated Weapon Stones.
Also a small amount ppl recieve 100's of these Way Back in the day...that sometime's makes it in the market but ever since boss gear started dropping these have not appeared there.
Cant Gather sharp/hards right now. Also cannot melt witch earring/scarla etc. to get sharp/hard.

 

You can also get one concentrated magical black stone (armor) from the node manager in Bashim Base (56~57).
Complete the first 3 quests and then you will get this one: Torrenandu's Declaration of War
