Elongated Hexagon Cut Gemstones

Six sides, stretched along one axis: two long parallel flanks and angled ends. The appeal is geometry — it is unmistakably a designed shape rather than a softened one, which is why it turns up in architectural and Deco-leaning settings where a round would look accidental.

Flat edges are the practical advantage. A straight side meets a straight band without a gap, and it lines up flush beside another stone, so it works as a center or as part of a cluster. The angled corners are blunter than a marquise point but still worth a bezel or a covering prong.
