Here are 2 very nice double terminated Quartz crystals that have petroleum inclusions. These crystals come from Baluchistan Pakistan.

These petroleum included double terminated quartz crystals are a recent discovery in the last few years and have quickly become very popular with collectors. The clarity and shape of these crystals have given them the name of "Diamond Quartz".

Not only have the fluorescent petroleum inclusions made these very popular, but in almost every pocket of petroleum, is a methane gas bubble. Most of these move within the oil as you turn the crystals.

Most bubbles you need magnification to see due to their size. It is also easier to see the bubbles if you use a uv light to fluoresce the petroleum.

Each of these crystals have at least 1 bubble that move.  The crystals weigh approx. 2.98 grams or 14.94 carats total weight. The larger of the two crystals measures approx. 1.57 cm long x 1.21 cm thick. The smaller measures approx. 1.22 cm long x 8.67 mm thick.

If you are interested in more of these, I have more in larger and smaller sizes not yet listed. Send me an email.
