Gemstones: Jade

"Come on Yan Yu. She's way better being honest with us and at least she doesn't fake soft voices to sound like siren's as most people do these days. It shows that she's open minded and free." Bai Chen simply countered.

He'd rather hear her blast his ears with her loudness than to hear disgusting coquettish voices from girls who try to get close to him.

Yan Yime eyes glistened with adoration and worship as she was glad that he didn't mind. Her whimp of a brother was really good at making her feel bad.

"Big brother Chen does treats me the best! Hear that Yan Yu!" She stick out her tongue at him and he just rolled his eyes.

" Just don't sound like a toad choking on a sugared turd."

" You...!! " Yan Yime choked.

*Kpai!

"Aiyo! What was that for?!" Yan Yu shielded his head and ran a few meters away from Bai Chen. His eyes looked like he had been wronged by his wife–Ah! ptui! ptui! ptui! That doesn't sound right.

Bai Chen lowered his hand back into his trouser pocket and lectured him a little. His face solemn as Yan Yime try to suppress her giggles.

" Little sisters are meant to be pampered and indulged on by their own brothers not picked on and nagged on."

" Alright I know my mistakes now." Yan Yu mumbled loudly. He glanced at his sister silently communicating that he'll deal with her later. This time around she rolled her eyes at him.

They spent their time talking and joking about until the topic switched to AI and Yan Yime couldn't keep up with them. She felt rather drained speaking with people of high intelligence like her brother and unfortunately Bai Chen was one of them. Except the cool version of geeks.

"See you around Big brother Chen." She waved as she turned around to leave. She had piano lessons at the moment.

"See you around then." Bai Chen simply winked and Yan Yime sank into a daze. Her face gotten into a deeper shade of red.

" Um yeah a-around... around school today." She quickly fled the place before she do something stupid.

" Bro stop doing that!" Yan Yu complained.

" Doing what?" Bai Chen raised his brows.

" Doing all this–" Yan Yu posed to look cool while twitching his face to seem handsome but instead he looked pathetically adorable like a chipmunk," And that anyhow!"

" I didn't do anything." Bai Chen lightly ignored him and started heading down the stairs. Yan Yu quickly followed him nagging all the way.

" Today we talk about Gemstones and their characteristics." An ordinary male teacher with an unassuming personality wrote on the board. A bold writing on the board said, " Gemstones."

Some of the girls looked quite excited about this opportunity to learn more about Gemstones. Naturally women loved anything that had to do with jewelry and sparkly things. The boys appeared uninterested.

" Oooh! We talk about diamonds and emaralds and rubies?!" A girl who wore her hair in a braid asked the teacher.

" Yes Miss Fin and we'll start with the most common and highly sought after in China, Jade. " The teacher spun the marker in his hand.

" Cool! My family does Jade business far away from the city." Miss Fin piqued.

" Okay then tell us what you know about Jade." The teacher asked.

" It's a raw material found in caves of China. It's characteristically green in colour but they've been different versions and colors found. Some include the Fulushao, Cockscomb red, emperor's green, sticky rice and Glass type blue."

" Well Miss Fin you just mentioned the examples of the kinds of Jade known. You are quite right. You see Jade is one of the symbols of Chinese culture and heritage as it is one of the most beautiful and wonderful gemstones in the world. It has been one of the treasures of China since 2950 bc. It was believed that it could cure illness related to the body functions and even preserve the dead. Though I couldn't possibly say that it's true. It was always kept in emperor's tombs and caves or even buried with the royal blood."

" Jade is known for it's green colour and it has been mined for a long period of time. It is divided into Jadeite and Nephrite."

" Jadeite is quite a costly one because it's the purest form of Jade. As to why Jade has different colors is dependent on the metal components inside them. for example if the Jadeite contained chromium metal,then it will be green in colour. And if it contains iron then it will be red.

As for Nephrite,it contains what we call tremolite,a pale grey or green amphibole which is responsible for it's robustness. Nephrite can also be classified based on colours like white,gray,green, topaz and black Jade."

" Jade naturally feels cool when it's touched and has been used by traditional medical practitioners to cure illness and even reduce fevers."
