Character created and owned by Emerald. References image by Fenix Dust.
Note: Jade does not have a mark designed, so she should be drawn without one.
Jade Stonesetter is a pegasus mare, and along with her twin brother Emerald, is the eldest of the Stonesetter-Wing siblings (though she was born first and is about an hour older than him).
She makes, uses, and sells her own shampoo. It's so good that wherever she goes, mares around her want to use whatever she uses - which she will gladly sell to them.
