There were three versions of this special run. GEM Stone Version 1 was a matte grulla ISH with four white socks and a blaze. Available in matte finish. 350 total pieces were produced for the Toy School and the Georgia Equine Miniaturists (GEM). 'Stone Mountain' is a well-known geographical landmark in the Atlanta and North Georgia area. Out of the 350 pieces, 150 of them were sent back to be modified as GEM Stone Version 2.
GEM Stone Version 2 was exactly the same, but had minimal pinto markings on the left side, and was available in matte finish. There were 150 models released, with 10 of those released in glossy finish as judge's models.

This version was a grulla ISH with leg barring and no white markings. 185 matte and 165 glossy models made. Limited to 350 pieces he was made for the Southern Model Horse Convention Live Show, but later sold through the Toy School.
