I read that yin is the texture in Jade, and yang is color. A colorless ice Jade has a lot of yin and no yang...thinking in those terms, about 'balance', the second bangle has a Fabulous balance of both body and color while remaining translucent.
The first does also, but the colors are more toned/muted, and gives a restful feel to me, whereas the second pops out in its color. I hope this describes why I adore it.
Yes you are describing exactly how I feel! the first one is calm and soothing. Peaceful and gentle. The second one is alive and vibrant in colour and personality. Both are earthy to me and makes me think of nature at it's best.
