This question is based on a false premise. Many crystalline substances are transparent, for example ice, quarts (in puure form, without falts etc.). Non transparent or translucant crystaline substances are probably so because of the way the crystal structure effects light entering the substance.
Water is liquid. Snow is crystalline. The crystalline structure of snow reflects white light. Water is transparent.
Nah I think it's transparent. Even slightly.
One type of classification system for polymers is either amorphous or semi-crystalline structure. This amorphous polymer (from thermal processing) lacks the crystalline components that scatter light, therefore it is transparent in appearance.
Quartz
Quartz is the most common crystalline mineral found on Earth. It can be colorless and transparent or have various colors due to impurities in its structure. Quartz is commonly found in a wide variety of geological settings.

The crystalline substances that are found naturally in the earth are known as minerals. There are literally hundreds of minerals on Earth that are used in everything from industrial purposes to consumption.
Sodium chloride at room temperature is a crystalline transparent substance.
Table salt (sodium chloride), sugar (sucrose), and quartz are examples of crystalline substances commonly found in everyday life.
Radiation is the type of heat transfer that can occur through transparent substances. Radiation is the transfer of heat energy in the form of electromagnetic waves, and it can pass through transparent materials like glass or air.
Radiation is the primary type of heat transfer that can occur through transparent substances. This is because radiation can pass through transparent materials like glass without significant absorption or change in temperature.
Glass is a transparent fusion product of inorganic substances that have cooled to a rigid state without crystallizing.
