For example, bread is baked as one piece of bread dough.

But afterwards, you can slice it apart into different sizes and shapes.

This would be like assembling a bookshelf from smaller parts into one large piece of furniture.

But recent evidence and observations have thrown some kinks in the armor of the top-down hypothesis.

Some younger star clusters are apparently in the outer halo, and even the oldest stars are metal-poor but not necessarily completely free of metal. A new hypothesis has been developed to account for these new discoveries. In essence, it states that large galaxies, like the Milky Way galaxy, formed from the combinations of small galaxies and star clusters.

Except in space, it was gravity, not wind, that ripped the big cloud apart.

Some of the smaller gas clouds wound up colliding with one another and combining, sort of like you would plop pieces of bread dough together to make a big pizza dough ball.

So the culet - the tiny little facet tucked away at the bottom of the diamond where no one can see it – is actually a gemmological hero. This means some of the light entering the stone at the top will escape out the bottom without having to do any of that lovely bouncy refracting diamonds are famous for. mean your diamond will shatter into a thousand tiny pieces at the drop of a hat.

A culet mainly protects the diamond during the cutting and polishing process – the tip is fairly well protected anyway after it’s placed in a setting.

If your chosen diamond been paying attention in class, you’ll have put two and two together and realized that when it comes to culets, it’s the size that counts.

Very simply, if your chosen diamond has a culet, make sure it’s a small one.

Thanks to some very technical stuff to do with crystallographic structural planes, even a small knock to the tip of a diamond could cause the entire bottom half to split.
