Gemstone Calculator: Your Life, Lucky and Fortune Stones by Lagna

These picks come from lordship alone. A gem is a support for a planet that already works for you, and the full chart decides whether that support is wanted. Before buying a stone, have the chart read, and have the stone tested for treatment and clarity. The remedy that always helps is work on the mind: mantra, daana and steady conduct.

Ruby carries the Sun. It supports confidence, health, standing at work and the relationship with the father. Wear it only when the Sun serves your lagna and is free of the avoid list. A stronger Sun also brings a stronger ego.

Pearl carries the Moon. It supports calm, sleep, memory and the relationship with the mother. It suits a Moon that rules a good house and sits weak by phase or by sign. A person already prone to heavy emotion should have the Moon read before wearing one.

Red Coral carries Mars. It supports energy, courage, property matters and the will to act. It suits a Mars that owns a kendra or trikona and stands weak. A hot-tempered chart, or Mars on the avoid list, needs a reading first.

Emerald carries Mercury. It supports speech, study, trade, writing and the nerves. It suits a Mercury that rules a good house and sits combust or debilitated. Mercury takes the nature of the planets with it, so read those before choosing the stone.

Yellow Sapphire carries Jupiter. It supports wisdom, children, wealth, the teacher and faith. It is the safest of the stones for most lagnas, and still not for every lagna. Jupiter ruling the 6th and 9th, or the 8th and 11th, needs the chart read first.

Diamond carries Venus, and White Sapphire is the usual substitute. It supports marriage, comfort, the arts and relationships. It suits a Venus that owns a kendra or trikona and sits weak. A Venus that rules a dusthana and no kendra or trikona, as for Sagittarius lagna, goes on the avoid list.

Blue Sapphire carries Saturn. It supports discipline, long work, service and endurance, and it acts fast. The tradition asks for a trial period and a reading before it is worn, whatever the lordship. Never wear it on lordship alone.

Hessonite carries Rahu. Rahu owns no sign, so its gem is chosen from the sign it sits in and the planets with it. It is worn during Rahu's dasha for a Rahu placed well, and only after a reading. On lordship alone it is never picked.

Cat's Eye carries Ketu. Like Rahu, Ketu owns no sign, and its gem depends on its dispositor and its house. It is worn during Ketu's dasha for a Ketu placed well, and only after a reading. On lordship alone it is never picked.
