Substitute stones
When Emerald is out of budget, its upratna — Peridot, Green Onyx — is used instead. A substitute is considered slower acting, so it is normally worn in a larger weight. The usual range is 3–6 carat, though the right weight depends on both body weight and the chart.
Who should avoid it
If Mercury rules the 6th, 8th or 12th house in your chart, Emerald 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
Emerald is suggested when Mercury rules a favourable house in your chart but sits weak. If Mercury rules a difficult house instead, the same stone can work against you.
How to wear it
- Wear it on a Wednesday morning at an auspicious time.
- Cleanse the ring in raw milk and clean water before wearing.
- Chant the mantra of Mercury 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.
