Diamond (Heera) – gemstone of Venus
Diamond, Heera or Vajra, is the gemstone of Venus. It is linked with love, marriage, comfort, beauty, art, vehicles and luxury. Venus is a benefic, but because it governs pleasures, a diamond worn for the wrong chart is said to encourage indulgence rather than harmony.

What Venus governs
Venus is the significator of love, the spouse in a man’s chart, marriage, art, music, beauty, vehicles, comfort and the reproductive system. A strong Venus gives charm, refined taste and harmonious relationships; a weak Venus shows dissatisfaction in relationships or lack of comforts. Venus is also the planet of diplomacy and creative work.
Who is it traditionally suggested for
Diamond is usually considered for Taurus and Libra Ascendants, where Venus is the Ascendant lord, and for Capricorn, Aquarius, Gemini and Virgo Ascendants, where it rules favourable houses. It is approached cautiously for Aries, Scorpio, Cancer, Leo, Sagittarius and Pisces Ascendants. A debilitated Venus in Virgo or a Venus close to the Sun is examined carefully.
Quality and wearing guidance
A colourless, flawless natural diamond is preferred; even half a carat to one carat is traditionally considered sufficient. Set in white gold or platinum and worn on the middle or ring finger on a Friday morning during the Venus Hora. White sapphire, zircon and opal are used as substitutes.
Caution
Gemstones amplify the planet they represent, including the houses it rules in your chart. Wear one only after a full chart review, never as a quick fix, and stop if you feel unwell or unsettled.
Gemstones strengthen, they do not fix
A gemstone amplifies its planet's results in every house that planet rules in your chart, including the difficult ones. That is why classical practice recommends a full chart review before wearing one, and why many astrologers prefer mantra, charity or lighter substitutes when a planet rules a challenging house.
Common questions
Who should wear Diamond (Heera) – gemstone of Venus?

Can anyone wear Diamond (Heera) – gemstone of Venus for luck?
No gemstone suits everyone. Because it strengthens all of its planet's significations, it can intensify difficulties when the planet rules a challenging house.
