Choudhary G. & Fernandes S. (2013) Inclusions in Indian Rubies. Presented at International Gemmological Conference (IGC) 2013 held in Vietnam from 12 -19 October 2013. Abstract in proceedings volume
An attempt was made to correlate the types of inclusions observed in rubies from various Indian states and their associated rock types. This study revealed a range of inclusions found in Indian rubies, which were of more or less similar type, pattern and appearance. No consistency was observed in the type and pattern of inclusion, restricted to a specific locality (states) and the associated rock types, although some of the minerals were identified only in specific locality such as hematite (in Chhattisgarh), chromite and green mica (in Orissa), and apatite and yellow spinel (in Tamil Nadu).
