Image of Diamond Dust, who is the best friend of Golden Veil. A couple years younger than Golden, Diamond was born in Canterlot and grew up with Golden Veil since they were fillies.
Having knack for jewelry making and knowing a real diamond from the rough, she decided to work with Golden when she opened the Golden Emerald and act as her partner and co-manager.
She is kind mare, loyal to her friends, and just a lover of jewelry altogether. After Golden Veil passed away, her will stated that Silver would be the one to inherit the business, but because of Silver running away to the Badlands, Diamond was tasked in keeping the business running until the day Silver returned.
Five years passed and after the events of Nightmare Moon's return, Silver returned home and visited the store, seeing that even then, his mother's business is still in operation, with Diamond doing an excellent job acting as manager. Silver offered to give her full ownership of the shop, but Diamond felt that Golden gave the store to her colt for a reason and should bide by her wishes to continue as the main owner of the Golden Emerald.
Because of this, Silver continues to earn his share in the revenue the business was getting, as a means of having a livelihood, even if he doesn't wish to run the store and go on with his dream as guardian. Diamond continues to manage the operations in the store, but would request Silver to come to Canterlot to help her should she be overwhelmed, to which he obliges.
