This green isn’t just rare… it’s elite. 💚
Imperial jadeite jade is one of the most expensive gemstones on earth.
And it’s not just about color.
It’s the combination of:
- Rich green
- Glowy luster
- Smooth texture
- Perfect uniformity
- Most importantly, untreated.
Almost no jade has all of these at once.
That’s why it’s one of the most desired gemstones in the East.

How To Test If Gold Is Real At Home
A $30 acid test kit can tell you whether your gold is real and help estimate its purity.
• Scratch the metal onto the testing stone• Apply the corresponding acid
• If the gold mark remains, the metal is that purity or higher
• If it disappears, it’s lower purity or not gold at all
Simple, inexpensive, and one of the fastest ways to screen gold before deeper testing.
