Ruby Depends on the House the Sun Rules
A second look at ruby is not a second list of solar virtues. It is the lagna test: which house Leo occupies, because that is the house a Sun stone will turn up.
Leo's place is the result
Ruby's astrological result is Sun-specific, and for career it matters when the Sun rules the 10th house, which happens when the lagna is Scorpio, because Leo then falls tenth. The same stone for a Virgo lagna rules the 12th, the house of loss, expense, and residence away from home. For a Leo lagna the Sun is the lagna lord, so ruby speaks to the body and the self. For a Sagittarius lagna Leo is the 9th, and ruby speaks to dharma, the father, and fortune. These four people can share a birthday season and cannot share a ruby story. The earlier question, whether ruby has any solar benefit at all, assumes the Sun was named. This question is what the naming actually buys.
Dignity does not erase rulership
The Sun exalted in Aries is strong, and the Sun fallen in Libra is compromised, and in both cases he still rules only Leo. Dignity changes how cleanly he does the job. It does not change the job. A fallen Sun ruling the 10th for a Scorpio lagna can still be the career planet, delivering status with more politics and more dependence on Venus, who disposits Libra. A ruby in that chart is a serious career step during the Sun's Vimshottari bhukti, taken with the fall in view. An exalted Sun ruling the 12th is a strong planet of loss and foreign life. Strength is not the same as a pleasant house. People buy ruby because the Sun is 'powerful' and then meet the 12th house at full volume.
Marriage and the father are side doors
The Sun rules the 7th only for an Aquarius lagna. Only then is ruby a direct marriage stone, and the D9 Navamsa still has to agree. In every other lagna, marriage remains the 7th lord and Venus, and ruby is a distraction if the pain is the spouse. The father is the Sun's karaka role and often the 9th house. A ruby for a father wound fits better when Leo is the 9th, or the Sun sits in the 9th, than when Leo is the 6th and you are about to amplify disputes. Sunday and gold remain the solar customs. They are not permission. Name the lagna, name Leo's house number, name the dasha, and only then decide whether the red stone has a department you are willing to live in.
Frequently asked questions
Which lagna has the plainest case for ruby?
Leo, because the Sun rules the self, if the dasha includes him and the harder houses he does not rule are acceptable. Scorpio is the plain career case, since the Sun rules the 10th.
Does an exalted Sun remove the need to check the house?
No. Exaltation in Aries improves delivery. The house Leo occupies is still the topic that gets louder.
Is this different from wearing ruby for confidence?
Confidence is a 1st-house word. It fits a Leo lagna better than a Capricorn lagna, where Leo is the 8th and ruby would turn up sudden change.
