I have always known about these, and have always awed those who own them. But I have never been given the opportunity to actually buy one, until now. I'd like to find out all about these blocks. How did the people obtain them? How many are there in the game? Is it a worthy investment, or would something like a Notch be better worth? And most importantly, I'd like a rough estimate of its value. Hypothetically, if you had, say, 100 Onyx, how much would you be willing to pay for these rare, and unobtainable blocks? No more then 1 Onyx, or up to 50 Onyx? All opinions are appreciated.
I'd also like to find out about Water blocks, and dirt backdrop (@Sirentist
?). How did the players get them? What are they worth?
