Gem Stones : Gem Stones (also called a Gem, Jewel, Semi Precious and Precious stone) is a mineral crystal which is used to make jewellery but certain rocks or organic materials that are not minerals are also used for jewellery and therefore considered as Gemstones. Gem stones are hard but some soft minerals are used in jewellery because of their physical properties.
A very famous Sanskrit Sholka says that ..
सशङ्खचक्रं सकिरीटकुण्डलं सपीतवस्त्रं सरसीरुहेक्षणम् ।
सहारवक्षस्स्थलशोभिकौस्तुभं नमामि विष्णुं शिरसा चतुर्भुजम् ॥
Apart from many kinds of weapons, Lord Vishnu bears ‘Kaustubha Mani’ (a gem named Kaustubh) on his chest. This gem is dearest to Him. This hymn shows that even before the whole universe came into being, Lord Vishnu did have an existence and the gem Kaustubh also existed along with Him.
Gemmology or the scientific and ethnic study of gemstones is an important and integral part of Astrology. Use of precious gems and stones has been an ancient practice in India. As per the beliefs this science is thousands of years old, however scriptural evidences show that concept of gemmology is as old as the creation itself.
