These heavily laden knuckles are not just a fashion statement...although for a long time that's what I thought. It is hard not to notice that just about everyone has these rings on! I started asking some questions. Major life transitions will often lead a person to sport a new rock or metal on their hand or around their arm. For example, students may suddenly have them on their fingers in order to concentrate and do well on exams, newlyweds have them to learn how to manage their temper and get in sync with their new partner, a graduate may wear one to bring in prosperity. And if you ask, you nearly always get the reply that someone else (Ma?) insisted that they see an astrologer, who treated them with a specific remedial gem.
Here, according to Vedic astrology, gems ward off the evil effects of planets and enhance the benefits of certain beneficial planets, while also adding to someone's beauty and character. Gems are thought to have curative powers, and are able to "change the stars" in someone's direction. If you need help in keeping the mind calm, increasing income or greatly reducing wasteful expenditures, there should be a gem remedy for you.
I agree that they do indeed add to the wearer's character and personality.
