It seems that all the pictures are real. There are natural mineral cracks, cotton wool and impurities in the crystal.
Although there are many fakes on the market now, amethyst and white crystal are not very expensive crystals to tell the truth.
So from the price point of view, it is meaningless to make fakes.
In particular, there are fewer fakes polished by the original stone crystal stone.
The bottom seven-star array pad is generally transparent glass.
Of course, the obsidian seven-star array also has the following obsidian pad directly. Because obsidian itself is very cheap.
And to be honest, about amethyst pendants, we should distinguish between true and false.
It's hard to tell whether it's stained glass or not from the appearance.
Because the crystal that is often used to make pendants will be very transparent.
More interestingly, many pendants just say "Crystal Pendant".
But it didn't say what crystal it was. It is incorrect to judge that it is amethyst only from purple.
Therefore, taking the pendant as an example, apart from the original stone carving, there is no need to care too much about whether it is natural or not.
Just focus on a good-looking one.
I hope I can help you.
