The beautiful Shivling is being nicely carved out of gemstone green aventurine with a greater degree of precision and perfection. Shivling is one of the most auspicious icons for the devotees of Lord Shiv, one of the Trinity Gods in Hinduism, the other two being Lord Brahma and Vishnu. It is a symbol for the worship of this Hindu god. The use of this symbol for worship is an ancient tradition in India extending back at least to the early Indus Valley civilization.
