PICTURES
; I AM A GRADUATE GEMOLOGIST WITH LIMITED PHOTOGRAPHY SKILLS. WHILE MY GEM & GEM TREATMENT SKILLS ARE VAST MY PHOTOGRAPH SKILLS ARE NOT. ONE NEEDS TO MAKE A CHOICE, BUY YOUR RARE GEMS AND JEWELRY FROM A GEMOLOGIST WHO CAN ASSURE THT WHAT YOU ARE BUYING IS WHAT YOU ARE BUYING OR A PHOTOGRAPHER WHO TAKES GREAT PHOTOS AND MAY NOT GET THE GEM CALL CORRECT. AS FAR AS ADDITIONAL PHOTOS, THAT TYPICALLY WILL NOT HAPPEN, SORRY. I RARELY GET THE TIME TO TAKE PHOTOS WHEN I GET MY SET UP AND RUNNING SO ASKING FOR SPECIAL OR ADDITIONAL PHOTOS WILL GET A HONEST
RESPONSE, BUT, NOT LIKELY THE ONE YOUR LOOKING FOR SO IF THE ONE PHOTO YOU NEED TO PURCHASE MY ONE OF A KIND ITEM IS NOT THERE YOU MIGHT HAVE TO CONSIDER ANOTHER SELLER THAT CAN PROVIDE YOU THE PHOTO YOU NEED OR TRY IT ON YOUR OWN HAND WHEN IT ARRIVES.
​THANKS IN ADVANCE, DON HOFLER GIA GG, AJP

Kornerupine
is a rare boro-silicate mineral with the formula (Mg,Fe2+)4(Al,Fe3+)6(SiO4,BO4)5(O,OH)2. It crystallizes in the orthorhombic - dipyramidal crystal system as brown, green, yellow to colorless slender tourmaline like prisms or in massive fibrous forms. It has a Mohs hardness of 7 and a specific gravity of 3.3 to 3.34.
It occurs in boron-rich volcanic and sedimentary rocks which have undergone high grade metamorphism. It is also found in metamorphosed anorthosite complexes.
Kornerupine is valued as a gemstone when it is found in translucent green to yellow shades. The emerald green varieties are especially sought after.
