 SCP-409 resembles a large quartz crystal, approximately 1.5 meters or 5 feet tall, and 0.6 meters or 2 feet wide. Any objects coming in contact with SCP-409 will begin to crystallize after 3 hours. This effect will occur in any material other than granite. The crystallization will spread by approximately 2.5 cm or 1 inch per minute, and will convert the entire object or organism. Subjects report this effect to be extremely painful and similar to frostbite. After complete crystallization, the object will begin to make snapping and creaking noises for approximately 20 minutes before bursting into thousands of fragments with great force. Anything touched by or touching a fragment will immediately begin to crystallize. Nothing at this time is able to reverse the effect in organic matter, including amputation of affected areas.
