The answer would be air. The other mediums have higher indices of refraction.

Quartz.
Quartz is a widely distributed mineral that has a high economic value. They are generally used as gemstones and as building materials.
Examples: coal, talc, quartz, magnetite, copper etc.
Each mineral has a unique composition and definite set of properties. Often an alternate may be found for some of these properties. For example there are many piezoelectric materials that will substitute for quartz in some applications.

Scott (AKA Cyclops) wears glasses or visor made from ruby quartz. Ruby quartz is one of the materials that is resistant to the beams his eyes produce.
Quartzite is also called quartz sand, silica quartz etc. Quartzite is the major raw materials to produce quartz or silica sand. Quartz crushing and grinding process are essential process in quartz crushing plant. In crushing quartz plant, we use jaw crusher, impact crusher, cone crusher, VSI crusher and mobile crusher as quartz crushing machines. Crushed quartzes are grinded into powder in grinding process using quartz powder plant. Ball mill, vertical mill, ultrafine mill are usually as machines for quartz grinding used in quartz powder plant.
Following Goldich Dissolution Series (Or going backwards by Bowen's Reaction Series), olivine weathers before Quartz. Quartz has a framework silicate structure and olivine has a isolated silicate structure.

Some crystalline materials (quartz for example) resonate at ultrasonic frequencies when an electric field is applied to the material.
