Quartz with Negative Carbonate Crystal with Petroleum and moving bubble. Minas Gerais, Brazil.
7 x 1.2 x 0.9 cm. 19.80 carats. Price: $ 350
A rounded top rectangular gem with 19.80 carats. It has a cavity, that used to be a carbonate crystal, maybe a Calcite or Siderite. This crystal got disolved and left what we call a negative crystal, with the shape of what it used to be. This negative crystal has a viscous orange fluid, natural crude oil, or petroleum, and a bubble inside. The bubble moves slowly due to the viscosity of the fluid. Unlike the Pakistani material that fluoresces bright blue, this Brazilian material has a very faint yellow fluorescence. It also has some fine Rutile needles going in different directions. It is quite a special inclusion piece.
Quartz with Tourmaline from Minas Gerais, Brazil.
2.7 x 1.9 x 1.7 cm. 32.40 carats. Price $ 320
A colorless Quartz gem with one long and gemmy green Tourmaline crystal piercing through near one corner and ending inside the gem near the opposite corner. Quite an aesthetic position. The Quartz has some gemminess with some internal silk and tension fractures, one that follows the Tourmaline. It has a good contrast of colors and the Tourmaline is very visible. With a loupe, you can see the termination inside the Quartz.
