THE QUESTION
What Are The Most Valuable Spinels?
Most stones have poor saturation, and their blue hues appear greyish. The finest and most valuable blue spinel colours can counter blue sapphire ones, with deep violet-blue to pure blue colours that are neither too dark nor too bright.
Note that spinels usually come in the same alluvial as corundum (ruby and sapphire).
