What Is a Solitaire Engagement Ring?
A solitaire engagement ring (or solitaire diamond ring) is a single diamond set alone on a band — no halo, no side stones. From the French solitaire (‘alone’), it’s the most recognizable ring silhouette in the world and ~35% of all engagement rings sold today.
- The classic — Tiffany & Co.’s 1886 six-prong ‘Tiffany Setting’ lifts the diamond above the band to maximize light; still the most-copied setting in the world.
- Why choose it — symbolically, a single stone for singular love; practically, every dollar of budget goes to the center stone instead of accent diamonds. The best choice when center-stone size and quality matter most.

Solitaire Settings — Cathedral, Trellis, Basket, and Prong Variations
The solitaire silhouette has several setting variants — each defines how the diamond is held and how it sits on the finger:
- Cathedral — center diamond elevated on metal arches rising from the band; maximum light entry, distinctive side profile. Needs a curved ring enhancer for flush pairing.
- Trellis — prongs cross under the stone in a side-visible X-pattern; sculptural and secure, common with round and cushion centers.
- Basket — diamond cradled in a metal basket with horizontal struts between prongs; refined side profile from every angle.
- 4-prong vs 6-prong — 4-prong (Tiffany-style) shows more diamond and reads modern; 6-prong holds more securely, reads traditional. Knife-edge + 6-prong is the historical Tiffany silhouette; princess and emerald cuts use 4 V-prongs at corners to protect edges.
