ABSTRACT:
A clear crystalline faceted substrate is provided with a coating of a colored transparent ink in order to enhance the appearance of the otherwise inexpensive gem stone. The ink is a permanent type ink made from n-propanol, n-butanol and diacetone alcohol which is soluble in a solution having a isopropyl alcohol 99% strength. Once the coating has been applied to a substrate such as a cubic zirconia to enhance the appearance of the gem stone, the coating can be removed by use of the solvent. A fresh coating of a different color may then be applied.
