The first step to selecting a ring with contrasting metals is to choose the material.
The combination of yellow gold with white is most popular because each is the affordable gold option, but other shades like rose are available.
Rose gold has a pinkish hue and blends with white as easily as the blushing bride to her groom.
If you like the neutral shade of green, believe it or not, you'll find it in sage gold.
This option is equally beautiful with white or yellow gold.
Platinum is the most expensive metal and more brilliant than white gold too.
It's also stronger and slightly longer lasting.
For an extremely elegant and subtle effect, try combining the lustrous platinum with white gold in your two tone engagement ring.
You won't be disappointed.
Of course, don't be discouraged from trying very affordable metals such as silver, copper and bronze.
The vivid colors in the bronze and copper interact playfully and dramatically with the gold.
Sterling silver and copper together will mark the special day in a most affordable way.
Once you chose your metals, then you must decide how you want them to weave through your ring.
The intricate knot of Celtic designs is popular, and filigree designs show off varying types of metals to great effect.
A most romantic idea is to buy interlocking rings which appear as two rings woven together like the affections of the bride and groom.
Finally, for a true feminine touch, a floral motif of rose gold on white or yellow gold produce an ethereal softness.
Any combination of metal is appropriate and beautiful for a two tone engagement ring.
Let's face facts -- buying a diamond engagement ring is one of the most important purchases that you will ever make.
It will set the tone for your marriage, and may be more meaningful to you than the purchase of your first home.
Not only that, but buying an engagement ring is a big investment.
Simply put, you want the best value for your money and you need to deal with someone that you can trust.
