What is a tapeworm?
Tapeworm — is a classic piece of jewelry whose design is built around a single gemstone without the use of additional inlays. The term comes from the French word solitaire , which translates as "sole" or "lonely." Most often, this term refers to a diamond engagement ring. However, solitaires can also be stud earrings or minimalist pendants with a single gemstone.

The design developed by Charles Lewis Tiffany in 1886 is considered the historical standard for the solitaire ring. In this model, the stone is raised above the band and secured with six thin metal prongs (prongs). Before this setting, gemstones were set deep within the metal shank. This innovative design allowed light to pass freely through the diamond's facets, maximizing its optical properties.
Distinctive features
The main characteristic of a solitaire is the absolute focus on the central stone. The design is completely free of side inlays, halos (halos of small stones), or complex shank decoration.

The most common stone setting is the prong setting. It uses four or six thin metal prongs. Four prongs visually make a round stone appear more square, while six emphasize its rounded shape and provide a more secure setting. An alternative option is the bezel setting. In this case, the stone is surrounded by a smooth metal band around the entire perimeter, protecting its edges from chipping and suitable for an active lifestyle.
A classic solitaire features a smooth metal base made of platinum, white, yellow, or rose gold. The simple metal form serves as a neutral backdrop, not distracting from the main element.
How to wear and what to combine with
Traditionally, a solitaire ring is used as an engagement ring and is worn on the ring finger. After the wedding, it is paired with a wedding band—either a classic smooth diamond or one featuring a band of small diamonds.

The minimalist design allows for the active use of stacking. A solitaire easily pairs on one finger with curved bands that wrap around the central stone, or with massive eternity rings. Mixing different metal shades is also acceptable when creating a set.

The lack of unnecessary details makes this piece easily suited to any dress code, from strict business formal to relaxed casual. In a jewelry set, the solitaire ring complements other single pieces, such as diamond studs or a pendant on a thin anchor chain.
