Do you know how the tradition of wearing an engagement ring on the fourth finger of the left hand started? The ancient Egyptians started this tradition symbolizing undying love as they believe the love vein Vena Amoris ran directly from this finger to the heart. Later in AD 860 the Pope Nicolas I made this practice of wearing gold engagement ring official.

Here are some engagement ring ideas.

You want to be unique. Consider getting a colored diamond. They are rarer than white diamonds. In fact, only one in 10,000 diamonds is a colored one. The colors range from yellow, pink and blue. Remember Jennifer Lopez's infamous pink diamond engagement ring ? A pink diamond ring is extremely rare and very expensive with prices starting from more than a hundred thousand. Yellow diamond is more common than the other colors and is definitely more attainable for a well to do couple. Generally, colored diamonds cost 25 to 50% more than white diamonds. In either case, choose a quality diamond by looking at the 4Cs.

Couples are also opting for bigger diamonds. The traditional one carat engagement ring has been superseded by 3 to 5 carat diamonds.

There are many new ideas for engagement rings. You can choose new diamond settings too. I understand round diamond is the most popular followed by the princess cut. The bezel setting is now very popular . Instead of the diamond being elevated, it is surrounded by metal. How about a tension set diamond engagement ring? The diamond seems to float and is actually held on its edges. It looks very cool.

Three stone rings are also hot now, the bigger center diamond is accented on both sides by smaller stones of the same shape. Guy Ritchie and Madonna,Phil Bronstein and Sharon Stone are two of the hottest Hollywood couples currently sporting them.

If you really want to be unique, consider antique diamond or heirloom diamond jewelry where the cutting was actually done manually by craftsman. You can then take out the old setting and place the diamond in a new modern setting. Alternatively, you can also consider getting a new diamond to be placed in your old setting thus making it unique.

The choice of metal is also important. Platinum is sought after for its hypoallergenic properties. It is stronger and heavier than gold and will remain tarnish free forever compared to gold. Other innovative use of metal include two toned rings and even rings that combine three metals.

If you want different gemstone, consider alternative gemstones like Sapphires, rubies and emeralds.

If money is an issue, consider getting a gemstone that looks like the real thing such as Cubic zirconia or moissanite. Moissanite rates an impressive 9.25 on the Mohs scale ( a diamond is a perfect 10) which is harder than emeralds and rubies.A one-carat moissanite cost about $500 while a diamond of the same size may set you back by $6,000. You can always upgrade to a diamond ring on your next wedding anniversary.
