Why Do Astrologers Recommend 5.25–9.25 Ratti Gemstones?
If you’ve ever consulted an astrologer for stones like Blue Sapphire (Neelam), Yellow Sapphire (Pukhraj), Emerald (Panna), or Ruby (Manik), you’ve probably noticed a pattern:
5.25, 6.25, 7.25, 8.25, 9.25 ratti —
rarely clean round numbers like 5 or 6.
Here’s why.
Body Weight Formula (Traditional Rule)
A commonly used guideline in Jyotish (Vedic astrology):
1 ratti per 10–12 kg of body weight
| Body Weight | Suggested Range |
|---|---|
| 50–55 kg | 5–5.5 ratti |
| 60–65 kg | 6–6.5 ratti |
| 70–75 kg | 7–7.5 ratti |
| 80–85 kg | 8–8.5 ratti |
| 90+ kg | 9–9.5 ratti |
Since most adults fall within this range, prescriptions naturally land between 5.25 and 9.25 ratti.
The “0.25 Ratti” Safety Margin
Historically, astrologers considered 5 ratti the minimum effective weight.
To avoid accidentally going under that threshold, they added 0.25 ratti as a buffer.
So instead of saying 5 ratti, they prescribed 5.25 ratti.
It was practical — not mystical.
Indian Cultural Symbolism (Avoiding Round Numbers)
In Indian tradition, round numbers symbolize completion.
That’s why donations are often:
-
501 (not 500)
-
1100 (not 1000)
-
2100 (not 2000)
Adding a little extra symbolizes growth and continuity.
Similarly:
-
5 → 5.25
-
6 → 6.25
It represents moving beyond stagnation — fitting for a remedial gemstone meant to improve life.
Quality Matters More Than Weight
Modern astrologers emphasize:
Purity × Weight = Astrological Potential
If quality is poor, increasing weight won’t help.
A smaller natural, untreated stone is generally preferred over a larger treated one.
For example:
-
5.5 ratti natural sapphire
✔ Better than -
8 ratti heavily treated sapphire
Energy clarity is believed to matter more than sheer size.
Not Everyone Needs 7+ Ratti
Weight depends on:
-
Planetary strength in the birth chart
-
Degree and house placement
-
Current planetary period (Dasha)
-
Body weight
-
Budget
Bigger is not automatically better.
Final Takeaway
The 5.25–9.25 ratti pattern comes from a blend of:
-
Body weight calculations
-
Early safety margins
-
Cultural avoidance of round numbers
-
Symbolism of “Sawa” (1.25 concept)
-
Modern emphasis on quality over size
More weight does not guarantee stronger results.
Authenticity and correct selection matter far more than size alone.
