A bullet shape diamond is a calibrated side stone — flat and straight across one end, tapering to a rounded or gently pointed tip at the other, like the profile of a bullet — set in mirrored pairs flanking a baguette or emerald-cut center stone. Guru Diam stocks 576 bullet diamonds on hand, calibrated and matched, IGI-gradable on request.
What is a bullet shape diamond?
A bullet is an elongated, step-faceted side stone with one flat end and one rounded or pointed end. The flat end sits flush against the corner of a center stone, and the tapered tip points outward, which is what makes the shape read as a bullet in profile. Like most calibrated side stones, bullets are cut to broad, quiet facets rather than high-fire brilliant faceting — the goal is to frame the center stone, not compete with it.
What bullet side stones are used for
Bullets are almost always sold and set in mirrored pairs, one on each side of a center stone, most commonly flanking a baguette or emerald-cut center in three-stone rings and Art Deco-style settings. The flat end aligns against the center stone’s corner while the tapered tip extends toward the shoulder of the ring, giving the eye a clean line running from center stone to shank. Bullets also show up in graduated channel-set bands, where a run of bullets narrows toward the ends of the band.
Bullet vs. Half Moon vs. Trapezoid
| Spec | Bullet | Half Moon | Trapezoid |
|---|---|---|---|
| Outline | Flat end + rounded/pointed tip | Crescent, one flat edge + curved edge | Four-sided, two parallel edges of different lengths |
| Symmetry | Mirrored pair (left/right) | Mirrored pair (left/right) | Straight or mirrored, often graduated |
| Typical center stone paired with | Baguette, emerald cut | Round, oval, cushion | Any — most common all-purpose side stone |
| Setting style | Three-stone, Art Deco, channel | Three-stone, Art Deco, cocktail | Three-stone, channel, eternity |
What to check before you buy
Two things matter more with bullets than with most side stones: the mirror match and the flat-end alignment. Confirm the pair tapers identically in both length and angle — even a small mismatch reads immediately once the stones sit on either side of a center stone — and check that the flat end is cut cleanly square, since that edge is what butts against the center stone’s corner. For channel-set runs, ask for the full graduated sequence rather than a handful of same-size pieces pulled from mixed lots.
Sourcing and matching
Bullet pairs live or die on the mirror match — the two stones need to taper identically so the ring reads symmetrical from either side. Guru Diam calibrates and mirrors bullet pairs in-house rather than pulling two similar loose stones from stock, CVD lab-grown, IGI-gradable on request.

FAQ
What is a bullet shape diamond used for? Bullet shape diamonds are calibrated side stones used in mirrored pairs to flank a center stone — most often a baguette or emerald cut — in three-stone rings and Art Deco-style settings. They’re also used in graduated channel-set bands.
How is a bullet shape different from a half moon or trapezoid? A bullet has one flat end and one rounded or pointed tip, giving it a directional taper. A half moon is a symmetrical crescent, and a trapezoid has two parallel edges of different lengths with no curved or pointed end — all three are calibrated side stones but with distinct outlines and pairing conventions.
How are bullet diamonds matched for a ring? Bullets are sold and set in mirrored pairs, cut or selected so both stones taper identically and sit symmetrically on either side of the center stone. Suppliers with in-house cutting can mirror pairs to spec rather than approximating from loose stock.
Are bullet shape diamonds certified? They’re sold as calibrated pair goods, IGI-gradable on request, the same convention used for other side-stone shapes. The center stone they flank is typically certified separately.
