RINGs

RING
In Western tradition, an engagement ring is a ring worn by a woman indicating her engagement to be married. Conventionally, the ring is presented as a betrothal gift by a man to his prospective bride while he proposes marriage or directly after she accepts his marriage proposal. It represents a formal agreement to future marriage.
In some countries, such as the United States and the United Kingdom, it is worn on the left-hand ring finger, while in other countries, such as Poland and Ukraine, it is customary for the ring to be worn on the right-hand. Similar traditions purportedly date to classical times, dating back from an early usage reportedly referring to the fourth finger of the left hand as containing the vena amoris or "vein of love".

In the United States and Canada today it is becoming more common, but still rare, that a woman will also buy her partner an engagement ring at the time of the engagement. These may be called male engagement rings or man-agement rings, which is a portmanteau of "man" and "engagement ring". This practice is more common in other countries.

Before agreeing to marry, a couple may choose to buy and wear pre-engagement rings, also called promise rings. After marrying, the couple may wear both engagement rings and wedding rings, or just their wedding rings, as they prefer.

Styles
This wedding set contains two separate rings, either of which could be worn separately. This wedding set contains two separate rings that look incomplete separately.
Most engagement rings, like any other kind of jewelry, can be classified according to their style. Since the middle of the 20th century, diamonds have widely featured in engagement rings. Solitaire rings have one single diamond. These traditional engagement rings may have different prong settings and bands. Another major category is engagement rings with side stones. Rings with a larger diamond set in the middle and smaller diamonds on the side fit under this category. Three-stone diamond engagement rings, sometimes called trinity rings or trilogy rings, are rings with three matching diamonds set horizontally in a row with the bigger stone in the center. The three diamonds on the ring are typically said to represent the couple's past, present, and future, but other people give religious significance to the arrangement. A wedding set, or bridal set, includes an engagement ring and a wedding band that match as a set. In some cases, the engagement ring looks "incomplete"; it is only when the two halves are assembled that the ring looks whole. In other cases, a wedding set consists of two rings that match stylistically and are worn stacked, although either piece would look appropriate as a separate ring. Although the wedding band is not to be worn until the wedding day, the two rings are usually sold together as a wedding set. After the wedding, the bride may choose to have the two pieces welded together, to increase convenience and reduce the likelihood of losing one ring.
