Here we see an excellent Fluorite specimen with well developed, cubed crystals and a fine square pattern along the faces. Actually, Okorusu Fluorite are relatively common. However, pieces of this quality date to the 1980s and are NOT common at all. Specimens with this fantastic deep green colour, gemminess and multiply-zoned phantoms are few and far between. This one, additionally, is pristine and displays nicely. I would also say that the deep green colour is better in person because I used minor backlight for better showing the colour. It is a phenomenal mini of the highest standard.
