Jupiter rules Thursday, the luck and good fortune planet, it's the planet that wants us to grow, prosper and flourish. With Jupiter on our side, Thursdays are all about money and finances. The day to evaluate financial goals, to make large purchases and investments. Thursday's are also great days for making difficult decisions, and a lucky day for making final decisions. So naturally, the top nail polish to wear on this day would be the Green Aventurine polish. Green Aventurine is all about prosperity, luck, and opportunity, and it's thought to be the luckiest of all the crystals. So make sure that you're wearing it when you go buy that dream car that's been on your vision board.
