Choose a planet above and this free lookup gives the substitute stone, or uparatna, that one modern Hindi book names for it, by the book’s own Hindi name written in Latin letters. The book is Pt. Kapil Mohan’s Ratna Uparatna aur Nag Nagina Sampurna Gyan (Randhir Prakashan, Haridwar). For the Sun it gives Sang Tamda, and for Ketu, Firoz. It is one book’s list: the book names no classical text, and other books, like our own Uparatna guide, list other stones.
How it works
The list comes from the book’s section on stones to wear in place of the pure gems, “shuddh ratnon ke sthan par”. It was read from a scan of the book and checked against the page image. The book gives one entry for each of the nine planets, and for the Moon, Mercury and Venus the entry has two names. The tool shows each name as the book gives it, in Latin letters with each word capitalised, the way Hindi is written in Hinglish.
| Planet | Main stone (our gem pages) | This book’s substitute |
|---|---|---|
| Sun | Ruby (manikya) | Sang Tamda |
| Moon | Pearl (moti) | Nimrusip or Shankh |
| Mars | Red coral (moonga) | Shakh Moonga |
| Mercury | Emerald (panna) | Sangwada and Sonamakkhi |
| Jupiter | Yellow sapphire (pukhraj) | Kahrav |
| Venus | Diamond (heera) | Tirmuli and Kansla |
| Saturn | Blue sapphire (neelam) | Jamuniya Neeli |
| Rahu | Hessonite (gomed) | Tursaya |
| Ketu | Cat’s eye (lehsunia) | Firoz |
No English gem name is added to the book’s names. The book gives none, and we have no named gem source that matches these Hindi names to stones, so an English name would be a guess. The main stone beside each planet is the one our gem pages use.
Reading the result
The first line gives the answer: for the planet you chose, the stone this book names, for example “For the Sun, this book’s substitute stone is Sang Tamda.” Where the book gives two names, both are shown: Nimrusip or Shankh for the Moon, as the book words it, and two names each for Mercury and Venus, which the book prints one after the other. Below the answer are the book, what kind of list it is, and the whole list for the nine planets, with your planet’s row marked and a link to our page on each main stone.
Where traditions differ
Lists of substitute stones vary a great deal. This book says the shastras give its stones, but it names no text, and its own contents page gives a second list that differs from this one. Our Uparatna guide gives the pairings met most often in English writing, and they are not the same as this book’s. Since no single list is authoritative, this tool names its one book and does not mix it with others. If your family or your astrologer follows another list, trust it.
What it does not do
It does not say whether you should wear a stone, which one, how heavy it should be or where to get it, and it does not judge a stone’s quality or whether it is natural. It does not give an English gem name for the book’s Hindi names. A gemstone is an educational topic here, as tradition describes it, and not a promise of any result.

Frequently asked questions
↳ What is an uparatna?
Uparatna, also written upratna, means a sub-gem: a lesser stone that some books name in place of one of the nine main gems. This tool gives one modern Hindi book's list, by the book's Hindi names.
↳ What is the substitute stone for the Sun in this book?
Sang Tamda. Pt. Kapil Mohan's Ratna Uparatna aur Nag Nagina Sampurna Gyan gives it in place of the Sun's pure gem, which is ruby (manikya) on our gem pages. Other books name other stones.
↳ Which book is the list from, and does it cite a classical text?
It is from Pt. Kapil Mohan's Ratna Uparatna aur Nag Nagina Sampurna Gyan (Randhir Prakashan, Haridwar), in the section "shuddh ratnon ke sthan par". The book says the shastras give these stones, but it does not name a text, and its own contents page gives a different list.
↳ Why are there no English names for these stones?
The book gives only Hindi names, and we have no named gem source that matches them to stones. Rather than guess, the tool shows the book's names in Latin letters, such as Sang Tamda, Shakh Moonga and Firoz.
↳ Why does your Uparatna guide give different stones?
Because lists differ. The Uparatna guide gives the pairings met most often in English writing, and this tool gives one book's list. Neither is authoritative. If your family or your astrologer follows another list, trust it.
↳ Is the planet I choose kept?
No. The lookup runs in your browser, and the planet you choose is not sent to us or kept. The first use asks you to confirm your email once, as on our other tools.
