Ratna (Gemstones): Introduction, Types, Qualities, Ayurvedic Uses

Ratnas or Gems are the precious stones which symbolize wealth and power. Gems are commonly used in the preparation of jewels. But in Rasashastra gems are being used for medicinal purposes after proper purification properties.


Gems are used extensively in Ayurvedic medicines. Gems are called Ratna. The term Ratna is coined due to their unique, radiant and appealing outlook when compared to other natural minerals. There are nine Ratnas and eight uparatnas (sub-gems) mentioned in Ayurvedic treatise. 


धनार्थिनो जनाः सर्वे रमन्तेऽस्मिन्नतीव यत् ।
अतो रत्नमिति प्रोक्तं शब्दशास्त्रविशारदैः ॥
(आयुर्वेदप्रकाश, ५/२)
dhanārthino janāḥ sarve ramante’sminnatīva yat |
ato ratnamiti proktaṃ śabdaśāstraviśāradaiḥ ||
(āyurvedaprakāśa, 5/2)
The thing which attracts people who wish to become rich, is called Ratna or Gem stone.

We can find references to various Ratnas in textbooks of rasashastra.

A gemstone or gem (also called a precious or semi-precious stone, or jewel) is a piece of attractive mineral, which-when cut and polished-is used to make jewelry or other adornmentsThe gems are precious stones, having a special kind of shining. In Hindu belief, the ratnas mitigate the bad effects of Navagrahas.

Gems in Astrology

In Astrology, it is believed that a person’s health and well-being is determined by the Grahas.
The effect of respective gems to specific Grahas is already explained in the table above.
Every cell in the human body is ultimately made up of electrons and nucleus. Just like the electrons orbit round the nucleus, so do the planets revolve around the Sun. Considering ‘Loka Purusha Samya’ concept here, it can be inferred that planets can have a major effect on Homo sapiens at quantum level.

These gems can draw energy from their particular Graha and channelize them into the wearer’s body. Thus they correct the deficit aura and help to subside the disease.

If this method of Dharana (Wearing) of Ratnas can be such a boon to cure diseases, it has another facet of mitigating and rejuvenating the body through internal administration as well. This has been mentioned in Rasa shastra texts. They can be converted into three forms for consumption –
Bhasma – calx,
Pishti – paste and
Dhruti – liquid / melted form.

Uses of gems in Ayurveda

रसे रसायने दाने धारणे देवतार्चने ।
सुलक्ष्याणि सुजातीनि रत्नन्युक्तानि सिद्धये ॥ (र.र.स. ४/७)
rase rasāyane dāne dhāraṇe devatārcane |
sulakṣyāṇi sujātīni ratnanyuktāni siddhaye || (ra.ra.sa. 4/7)
Good quality Ratnas are used in processing of Parada, for rejuvenation, for donation, in worshiping Deities.

Significance of Pishti

Ratnas are well known to be of Sheeta guna and are heat sensitive. In order to preserve their Sheetatva , Anagni puta is given by triturating them in liquid media and exposing  to Sun till the required Lakshanas are obtained.  By this method, not only is its potency preserved but one can convert them into nanoparticle size which is desired for better absorption and assimilation.

Diamonds have been known to humankind and used as decorative items since ancient times; some of the earliest references can be traced to India.Diamond’s hardness and high dispersion of light – giving the diamond its characteristic “fire” – make it useful for industrial applications and desirable as jewelry.
Diamonds are such a highly traded commodity that multiple organizations have been created for grading and certifying them based on the four Cs, which are carat, cut, color, and clarity. Other characteristics, such as shape and presence or lack of fluorescence, also affect the desirability and thus the value of a diamond used for jewelry.
