The difference between half and full eternity rings has nothing to do with whether the love or sentiment behind them will last halfway to infinity or all the way there. Rather, it refers to the way eternity rings are set, and how the gemstones on the band are placed.
A half eternity ring has somewhat less than a full circle of gems, perhaps only two to four, but the back side of the ring is a plain band. A full eternity ring has studs or gems all the way around the ring, and it may incorporate diamonds, rubies, emeralds or other gems. Both rings are the same thickness and width all the way around.
The most obvious difference between an eternity ring and other styles is the fact that there isn't one single focal point on the eternity ring. And there is no difference in the width of the band, all the way around. It doesn't matter whether the ring was designed as a promise ring, or one symbolizing a wedding or engagement ceremony.
There isn't an eternity ring with a solitaire setting. You won't see a marquise cut emerald with smaller diamonds around it, like you do in other ring styles. All the gems in an eternity ring are generally the same shape, cut and style. Half and full eternity rings seem simple when you compare them to other types of gem settings, and they are both versatile and appealing.
A stacking full eternity ring may include an engagement and wedding ring stacked, or perhaps anniversary rings added, as well. They look stunning when they are stacked on your finger. If the bands are thin enough, you can even place four or five rings together on your finger.
If all your eternity rings are full in type and have silver, platinum, white gold and diamonds, the sparkle can be quite brilliant, since there are so many gems all cut the same, and set in the same way. You can pair those rings with diamond tennis bracelets on your wrist for even the most elegant of events. It will scarcely matter the type of dress you wear with all the glamor your rings and bracelets show off. An eternity ring is so much more than a simple band with diamonds on it. It is also a very sound investment, a symbol of the beauty of illusion, and it shows the wonder and perhaps the folly of humanity's quest for immortality and eternity.
Within this desire for everlasting eternity, perhaps we find some small hope, while others find optimism and expectation, which can enable us to find one perfect object to give to someone. It's a symbol of eternal love, which is the most ultimate bond we can achieve on Earth. None of us will truly live forever, but we can still symbolize a love that will last as long as we do, and perhaps beyond that. If you enter this wondrous world, you can then imagine the love and hope displayed by full eternity rings.
