"A Victim Of Its Beauty
Yogo sapphire is as much a victim of its beauty as its past. … the stones have a
crisp, violet-blue color that seems almost pastel when compared with the more
saturate blues of heat treated Burma’s, Kashmir’s and Sri Lanka’s best. For this
reason, Yogo beauty doesn’t quite fit in with darker contemporary notions of
sapphire excellence…. vibrant violet-blue stones... jar with modern sapphire color
"Yogo sapphires are known for their uniform, well-saturated blue color; relative
absence of inclusions and zonation; and high luster and brilliance in both artificial
and natural light; they do not require heat treatment. "
