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).

With over ten years of marketing experience, I finally decided to settle down in Bangkok to work in an area that I have always been interested in: the gemstones industry. I'm still learning how the market works on a daily basis, and I enjoy sharing my experience with those who are interested in learning more about gems in general.
