I can never remember the difference between etymology and entomology and I can't put into words how much that bugs me.

Well awktshualy...the definition says reflect, and while diamonds reflect internally, they refract light externally, so, the diamond is not bright because it reflects (those reflections are on the inside) they shine because they refract

But isn't their shine mostly due to the internal reflection rather than external refraction? That's why the gems are cut angularly, to help with the internal reflection.

You can only observe the external properties since you are on the outside

By that logic, glass mirrors also work by refraction, because it refracts out of the glass before it reaches your eye.

Albert knows that they actually do shine. This meme could only have been more wrong if it was Plank.

Yet another way this is wrong: the primary cause of the adamantine lustre of diamonds is refraction. Any old hunk of metal can reflect light.

Isn't it caused by internal reflection? That, by definition, is what happens when the light doesn't refract out of the diamond.

I considered that when posting, though the play of prismatic colors which defines the diamond's unique lustre, in addition to that same tendency toward internal reflection, are both ultimately caused by the extraordinary refractory properties of the crystal structure, and the refracted light coming out of the diamond after internal reflection is the constituent of the "shine"

If a post labeled, essentially, 'idiot', has two English mistakes in glurge written for a genius, is that irony?

Nothing is more on brand than a language pedant making grammar mistakes. What do you expect of person who thinks memorizing rules is the hallmark of intelligence?

If that gets stuck in my head I'm gonna be so fucking mad.

The "shining" nature of diamonds is not due to their reflective properties, it's due to how they refract.
