Substitute stones
When Red Coral is out of budget, its upratna — Carnelian — is used instead. A substitute is considered slower acting, so it is normally worn in a larger weight. The usual range is 5–9 carat, though the right weight depends on both body weight and the chart.
Who should avoid it
If Mars rules the 6th, 8th or 12th house in your chart, Red Coral is generally avoided — strengthening the planet also strengthens that house. Starting a new stone during pregnancy, ongoing medical treatment or a period of high stress warrants a consultation first.
Who should wear it
Red Coral is suggested when Mars rules a favourable house in your chart but sits weak. If Mars rules a difficult house instead, the same stone can work against you.
How to wear it
- Wear it on a Tuesday morning at an auspicious time.
- Cleanse the ring in raw milk and clean water before wearing.
- Chant the mantra of Mars 108 times.
- The stone should touch the skin — this is considered essential.
Caution: blue sapphire, hessonite and cat's eye should be trialled before being worn permanently. Have your chart read by a qualified astrologer before any gemstone.
