One of the most iconic props associated with Captain Jean-Luc Picard, his “desk crystal” appears prominently in no fewer than 78 episodes of Star Trek: The Next Generation, often in his hands during the iconic speeches on moral and ethical issues that are so fundamental to the character of Star Trek’s most ruminative captain.
This Roddenberry.com Legacy Series prop re-creation is made of high-end lead crystal: a special blend of optical-grade borosilicate glass with an extremely high refractive index, clear enough for use in lenses, prisms, and other optics. Its impressive heft makes it suitable for use as a paperweight, and it's just the right size to be waved about in one’s hand for oratorical emphasis, as its prismatic properties glimmer and sparkle in the light. The crystals are each meticulously formed, wet-ground, and polished by hand at a company that specializes in fine crystal glassware and chandeliers.
The 3D geometry of the crystal was obsessively reconstructed using digital 3D modeling software, referencing and reconciling hundreds of film frames of the crystal’s appearances across the seasons of TNG. ST crew members and vendors involved in the original production of the show were consulted and this went through approximately 30 physical prototypes before we were confident the sizing, along with the number of facets and their orientation, was as accurate as possible with with all available reference materials.
