TīmeklisWhen it comes to the clarity enhancement of gems with oils/resins, a common belief is that the refractive index (RI) match between the host gem and the filler is critical. During the 1990s, the use of Opticon (n=1.545) instead of cedarwood oil (n=1.512) was said to be vastly superior in masking fissures in emeralds (Hughes, 1998). TīmeklisRefractive index represents a ratio between the speed of light in a vacuum vs. the speed of light in another material. In other words, it explains how much light slows down in other more optically dense materials. Spinel has an RI of about 1.72. This means light travels 1.72 times slower in spinel than in a vacuum (or air). Fraunhofer lines
