Gemstones or Ratna still hold significant value in many cultures. Traditionally, these gems have been classified as precious and semi-precious gemstones. In Western astrology, they are referred to the same way; in Vedic astrology, precious gemstones are called Mukhya ratna, whereas semi-precious stones are called “Upratnas.” This blog will highlight the difference between the two and the importance each of these has in astrology.
Gemstones are mineral crystals mined from the earth's surface. While many are mined from the earth, few gems, like coral and pearls, are found underwater. The classification of precious and semi-precious gems in ancient civilization was based on rarity, beauty, and symbolic significance.

The big fours, diamond, emerald stone, ruby, and sapphire, were classified as precious as they were used in religious ceremonies and were a symbol of power and status. Semi-precious stones like turquoise stone, pearl stone, and amethyst stone were used as carved jewelry because they are soft and can be carved easily.
Gemstones that are rare, high quality, and expensive are considered precious. Traditionally there are four precious ratnas known namely diamond, emeralds, rubies and sapphire stone. However, the concept of precious gemstones has now been redefined, with rarity and exclusivity adding to the classification factors.
For instance, Alexandrite stone is a rare and expensive gemstone with limited availability. Thus, it can be categorized as precious in terms of value. Emerald stone is precious in terms of cultural significance. In Indian culture, panna stone is considered precious as it symbolizes wealth and prosperity.

A semi-precious stone is a natural gemstone that is either obtained from the earth’s surface or from underwater. Semi-precious does not mean they are lower or inferior to their counterparts. Unlike precious gemstones, they also hold significance in various cultures. For instance, in Indian Jyotish semi precious stones are referred as Upratnas.
They are used as substitutes for precious stones or Mukhyrtanas. Citrine stone, a semi-precious stone for money, is the best substitute for yellow sapphire stone. Those who find it difficult to afford Pukhraj stone can opt for a suitable alternative like citrine.

Here are the key differences between the two:
Precious stones are rarer than semi-precious. For instance, Burma ruby stone with an intense red color is rare to find. The best old Burma rubies of high-carat weight, clarity, and vivid color are not readily available. Hence, these are considered precious and rare. Semi precious gemstones like citrine, amethyst, jade, neeli stone are easily available.

The major difference between precious vs semi precious stones lies in their value. Precious ones are expensive. The blue sapphire stone price starts from INR 5,000 to INR 1 lakh and more. Neeli or Iolite, the substitute for Neelam stone, on the other hand, is not expensive. Well, the reverse may also be true.
For example, the 4C’s influence the quality and value of the gemstones. So, a high-carat weight blue sapphire of poor quality (pale color, highly included) is not always expensive. One can opt for a high-quality semi-precious stone like aquamarine stone in this case.
The market trends play an important role in assessing the value of the stone. For instance, emerald stone is considered a highly prestigious stone because of its popularity among elite people.
When considering precious vs semi-precious stones, the former are more durable than the latter. Natural precious gems like ruby stone have a hardness of 9, making them scratch-resistant.
The semi-precious counterparts, like turquoise with a hardness of 5, are less durable. Thus, one can say that precious stones are highly valued for their exceptional durability and longevity, which are the key reasons behind their desirability and worth.
In Indian Vedic astrology, precious gems like Panna Ratna, Manik stone, Neelam, and Heera have been associated with specific planets. Pukhraj is associated with Jupiter graha, while Neelam stone is linked with the most powerful Shani.

Indian Jyotish resonates around the planets and their influence on the person. Referring to the birth chart, the position of the planet is analyzed, and gemstones are decided. For instance, the best remedy for ill-placed Shani is wearing a blue sapphire stone.
So, are semi-precious stones not worth it? Yes, they have. These are valued for their healing properties. Meditating with an amethyst crystal helps the person with stress relief and better sleep. Moreover, they are used as substitutes in Vedic culture.
Green Onyx, a semi-precious stone, is an alternative to emerald stone. For individuals who have an ill-placed Mercury panna, it is the main gemstone to be worn. However, with factors such as availability and affordability, green onyx can be used as an effective substitute for removing mercury ill effects.

Generally, it is advisable to wear mukhyartana or primary gemstones like (emeralds, diamonds, rubies, and sapphires) to get rid of the malefic effects of the planets. However, one can also choose alternatives like green onyx, zircon, spinel, neeli, and sunela, which offer similar benefits.
To conclude, identifying the difference between precious and semi-precious gemstones is important to know the price and their relevance in astrology.
