Memory Jades had ranks of their own. From lowest to highest, one had: white, green, blue, violet, red, black and finally, crystalline Memory Jades. These ranks didn't necessarily correspond to how valuable what was inside it was, but what it did correspond to was just how much information a Memory Jade could withstand and also the kind of information it could store.
Due to the distortion of the Spiritual Qi pool, Ryu hadn't had any idea what the color of the Memory Jade was previously, but now that he held it in his hand, he couldn't help but be baffled.
White, green and blue Memory Jades could easily store up to Heaven Grade techniques, even some simpler Mystical Grade techniques would fit. Violet Memory Jades were large enough that even an Origin Grade technique could fit and still have plenty of room to spare.
