Symbolism

Why are Rings Worn on the Left Hand?
From the biggest diamond engagement ring to the smallest, they are invariably worn on the left hand. The origin of this practice is still unclear, but there are several theories.
According to one, people believed the third finger possessed a vein directly connected to the heart. Because the left hand is nearer to the heart than the right, the ring was placed there. 
The ancients believed that the third finger was related to the god Apollo and the heart. By putting the ring there, energy is sent to the heart. This boosts the life of the individual wearing it.
Another theory is that it is meant to protect the jewelry from damage. Majority of people are right handed. Putting the ring there would make it susceptible to damage, so it is put on the left.
Budget and Tips for Buyers
The”rule” is that the ring should be worth two months’ salary. But that rule isn’t written in stone. Don’t make the mistake of equating your love with the cost of the ring. Don’t let the salespeople dictate how much you should spend.
Pay attention to detail. Do you want a ring with multiple stones or just one? Will the ring be simple and elegant, or will it be elaborate? It should depend on what your special someone likes.
Whether you are going to buy the biggest diamond engagement ring or not, pay close attention to the four Cs – carat, clarity, cut and color. Don’t forget to assess the setting. It can go a long way towards beautifying the ring.
