Mineral: Hydrothermally Grown Synthetic Silicon Dioxide
Description: R&D XTALS LLC, Cleveland, Cuyahoga Co., Ohio, United States 3.7 cm x 3.8 cm x 2.4 cm This specimen (JKB906) is another example of a “Vlad Twin”. This example puts a “twist” to these aesthetic twins; it has another crystal at the back. This “tail” at the backend is rather unique and involves even more calculations and luck in trying to grow three seed crystals at the same time.
