The Diamond Solitaire

The diamond solitaire ring, which usually features a single diamond in a precious metal setting is probably the most iconic and timeless piece of jewellery there is. Its simplicity in design and symbol of everlasting love makes it one of the most sought after and best-selling jewellery items here at O’Reilly’s.

The solitaire diamond ring has a long history. Its origins can be traced back to Ancient Roman times when a ring symbolised life and eternity and was used as a public pledge of marriage between a couple. The discovery of diamond mines in Africa during the Victorian era made diamonds more readily available and the style became popular with married couples to be.

In 1948 De Beers first introduced the famous phrase “A diamond is forever”, confirming the solitaire ring’s position as a true jewellery icon and the ultimate symbol of enduring love. 

Although there are many styles of a diamond ring, the solitaire is a classic design with a timeless quality that makes it universally appealing.

It is versatile and simple, worn on its own, paired with an eternity band or a wedding band, there is a diamond solitaire ring to suit every taste and lifestyle.
