The term "diamond solitaire" refers to a type of jewelry featuring only one diamond. Diamond solitaires may be rings, necklaces or earrings.
Diamond solitaires are traditionally associated with significant occasions, such as notable birthdays, anniversaries and engagements. In fact, a survey conducted by TheKnot reported that 25 percent of more than 7,000 women received diamond solitaire engagement rings.
When choosing a diamond shape for a solitaire, most people choose "round brilliant." This shape is cut specifically to be multifaceted, showing off the sparkle and depth of the diamond. Other shapes suitable for solitaire jewelry include "cushion," "princess," "radiant" and "pear."
Deciding on the setting type is also important for diamond solitaire jewelry. For rings, many people opt for a minimal "prong" setting in order to maximize visibility of the singular diamond. The prongs are thin, while at the same time long enough to hold the diamond out from and above the ring. The Tiffany 6-prong setting remains the most iconic and archetypal style for an engagement ring.
Other settings suited to diamond solitaires include "cathedral" (exposing two sides of the diamond), "bezel" (holding the diamond securely in a sleek and modern surround) and "tension" (where the ring does not join up but instead holds the diamond between its two ends, almost like a spring or a vice).
