SUMMARY
The discussion centers on identifying a crystal with a refractive index of 1.33, which is the same as that of water. The crystal in question is identified as cryolite, a mineral known for its unique optical properties. The user shares a personal anecdote about witnessing the crystal's optical illusion when submerged in water. Links to additional resources, including a Wikipedia page and an eBay listing for cryolite, are provided for further exploration.
