Tarev,
Sorry to inform you. You have a reversion back to the original spices. Called Sansevieria trifasciata. The gold edge ones are called Sansevieria trifasciata Laurentii. Named after the man who first discovered a gold edge on one of his regular trifasciata. It probably grew from a stem cutting below the ground level. Below is a picture of several large gold edged leaves that I rooted in a pot several years ago. All new growth is regular but beautiful.
