Bright Stone (Glowstone Variant)

A block formed from merging Glowstone Dust and Diamond, would be a brightly glowing white/gold and while as bright as Glowstone, would spread it's light over a wider area.

If clumped together or introduced to a redstone signal or such, would glow even brighter, and cause burning damage to any living thing in it's light radius, the same way sunlight deals damage to zombies.
