A thing to remember here is that these posts are strictly meant for the particular planet position. Like, today we are looking at Venus in Gemini, so the description given here may change for you if your Venus is although in the sign of Gemini but with conjunction with or aspected by other planets.

So, lets see what Venus can do in Gemini without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent --

Venus is beauty, desire and love, liquid money, Venus is beauty, desire and love. Venus is the main significator of marriage. Venus represents girlfriend or wife for a man. Venus is the significator of all relations, may it be husband-wife or mother-daughter. Philosophically speaking, Venus is also the cause of all the sufferings in our life. How? Because Venus represents our desires and we get pain and suffering in our life only when our desires are not fulfilled.

Gemini is the 3rd sign of zodiac belt, so it represents many things related with 3rd house of horoscope like, Communication Skills (either written, oral or even by sign language), Marketing, Business etc. It is a sign basically related with communications and business ideas. Gemini is divided into 2 and half nakshatra of Mrigashira, Ardra and Punarvasu. Gemini's lord is Mercury, which is significator of Communications.

Now, Venus is in communicative sign of Gemini. 1st of all, Gemini is ruled by Mercury, which is friend of Venus. So, Venus is in very good dignity here. Naturally, when these people look for love and partners, they get a partner who is very communicative. Communication with partner becomes the foundation of their relationship. If couple is unable to communicate properly then relation may not last long. As Venus is also wealth & beauty and Gemini is sign of Marketing and Selling, these people have a very beautiful way of speaking and can make good wealth through business and marketing. So, they earn wealth through their communication. But as we mainly look for love, desires and relations through Venus, here Venus is in Mercury ruled sign. Mercury represents Travelling. So, this Venus-Mercury exchange can actually lead to person having many love stories and it even becomes karaka of infidelity. So, It is better to have good communication with your partner to avoid all this scenario.  

Now, where does these things differ for different people born with Venus in Gemini. It depends on the Nakshtra Venus is placed in. So, if Venus is in Mrigshira Nakshatra, then it will be impacted by Mars as Mars is its lord. If Venus is in Ardra Nakshatra, then we need to assess Venus' result through Rahu's position as Ardra is ruled by Rahu. If Venus is in Punarvasu Nakshatra, then we need to check Jupiter's position.

Sign lord wise, Mercury is lord of Gemini. So, to really assess results of Venus in Gemini, we need to see how Venus is placed.
