In the context of rings, "solitaire" refers to a style where a single diamond or gemstone is featured prominently, usually in a simple and elegant setting. This design emphasises the beauty and brilliance of the single stone without any distraction from other stones. The solitaire setting is particularly popular for engagement rings but is also used in other types of fine jewellery. The solitaire ring's elegance lies in its simplicity and the way it showcases the natural beauty of a single stone, making it a perennial favourite for engagement rings and other significant pieces of jewellery.
