Emerald or Emerine
The Emeralds, also known as Emerines, are a green color mutation discovered by Ron Tremper. Although the Emeralds are not a completely green gecko like the orange in Tangerines or the white in Blizzards, they still show different shades of green. Typically they will have different patterns, either Banded, Jungle, Striped, or Reverse Stripe.
The original Emeralds first occurred in Ron's collection in 2004. They are featured in his book, "The Herpetoculture of Leopard Geckos." Currently the genetics are still to be determined, but as of right now, breeding Emerald to Emerald will create 100% Emeralds.
