Spectrum of gems

In this world of gems ruled by red rubies, blue turquoises and green emaralds, it is easy to break in to anything with a not bad hammer. But on some rarest of moments, there arises a few, who are a fusion of these bright colours inside, yet clad in the unbreakable armour of celestially enchanted diamond, cut in a way to shine even in the most fading star lights. Best of anvils made with the toughest of blunt matter will shatter trying to break through the shining armour of unbreakable will. But yet a cauldron of liquid oxygen is all it takes to erode that blunt mein and reveal the colourful inside.
It's always a waste of time to try break in to the hardest of evasive minds, trick is to dissolve away that shell of enigmatic wisdom distancing itself from the realms of this nihilistic world.
