Takahashi et al. ([5]) successfully produced lab-grown scepter quartz using the microchannel epitaxy concept by artificially masking the prism faces of a quartz crystal with silver and leaving the apex unmasked. First, crystals tend to grow roughly perpendicular to the walls of the vein because any other orientation would put these crystals at a disadvantage in the competition with other crystals for space. All specimens pictured from the Lyndhurst area, Ontario, Canada Quartz is a common and deceptively simple mineral that keeps giving us riddles.
