They cut the center extra wide so you could see the Olivine inclusion.
This photo's width is 3.83mm! Just imagine how small this crystal is...
Many think of Clarity and Inclusions in the perspective of diamonds. There is a negative perception of inclusions; they drive the price down, they make my diamond look bad, I want my diamond to be "perfect", etc. Clarity and Inclusions occur in a variety of other stones and can actually drive prices UP! Having doubts? You're not alone. It's time to change our perception of "Clarity." Inclusions can be beautiful. Enjoy the look of star sapphires? Cat's eye gems? Both of those phenomena are caused by needle-like, crystal inclusions! Silk/needle-like inclusions in Ruby can give it a satin luster that is prized- and pricey! A recent discovery in an Oregon sourced Labradorite can catch your eye as well. Gem quality Labradorite from that location is typically prized for its red, orange, and green colors as well as tiny inclusions of copper platelets that give the stone a gorgeous sheen. Other conclusions are rarer- this includes Olivine. In this case, because Olivine inclusions are rare the stone was cut to showcase the inclusion; as it happens if you find Olivine inclusions in Labradorite it typically indicates an origin in Oregon. Say that 10x fast! So don't write off inclusions just yet! Sometimes they are pretty, add value, and/or indicate where your stone may have originated.
