Nigerian Sapphire
 
Yes, you´re right this is a tiny gem. When I bought the rough with 4.45 cts. I hoped to have a result slightly over one carat. Not visible was a crack at the place of the pavillions tip. So I had to cut and cut and it became smaller and smaller. All the trouble zones with inclusions and cracks left and it became smaller and smaller, but I was not willing to give it up. The result is an outstanding, flawless little gem with 100% meetpoints, great vivid colour and just enough colourzoning to show its natural origin.
  0.44 cts., 4.1 x 4.1 x 2.9 mm.
sold

Additionally it has an unbelievable dispersion that increases the brilliance . This beauty was hide in big parcel of sapphires from Songea and it really could be mistaken for an corundum, but all the tests says it is Rhodolite Garnet, there is a crack at half past five that is well hided under the corners of the crown.
