It's diffuse + ambient that should be kept under 1.
So :
#declare GOLDDARK = material {texture { pigment {rgb <0.81, 0.71, 0.23>} 
finish
{diffuse 0.5 ambient 0.5 specular 1} } }

Normally, ambient should be kept under 0.2. As it's a metal, it's better 
to set it at zero. So, my suggestion will be :

#declare GOLDDARK = material {texture { pigment {rgb <0.81, 0.71, 0.23>} 
finish
{diffuse 0.7 ambient 0 specular 1 metallic} } }

Or :

#declare GOLDDARK = material {texture { pigment {rgb <0.81, 0.71, 0.23>} 
finish
{diffuse 0.5 ambient 0 specular 1 metallic reflection{ 0.7 metallic} } } }
