Really?? I think its a fake diamond.
It's a fake diamond in the same way that an emerald is a fake diamond. As in, not a fake diamond at all, but rather an entirely different mineral.
The only reason to buy a real natural diamond is so that you can brag about it to people, to use it as a form of conspicuous consumption. "Hey look at this ridiculously overpriced thing I just wasted a ton of money on, isn't it lovely?" It's like putting spinning rims on your gold plated jet-ski. It automatically earns you a highlight post on the Antimustachian Wall of Shame and Comedy.
Here’s the thing. You said a "CZ is a fake diamond"
Is it in the same family? Yes. No one’s arguing that.
As someone who is a scientist who studies geology, I am telling you, specifically, in science, no one calls CZ a fake diamond. If you want to be “specific” like you said, then you shouldn’t either. They’re not the same thing.
If you’re saying “diamond family” you’re referring to the taxonomic grouping of gems, which includes things from emeralds to rubies to opals.
So your reasoning for calling a CZ a fake diamond is because random people “call the synthetic ones fake diamonds?” Let’s get synthetic sapphires and synthetic emeralds in there, then, too.
Also, calling something a gemstone or a mineral? It’s not one or the other, that’s not how taxonomy works. They’re both. CZ is a gemstone and a member of the mineral kingdom. But that’s not what you said. You said a CZ is a fake diamond, which is not true unless you’re okay with calling all synthetic gemstones of the mineral kingdom fake diamonds, which means you’d call synthetic alexandrite, amethyst, and spinel fake diamonds, too. Which you said you don’t.
It’s okay to just admit you’re wrong, you know?
