A Baguette is a narrow, rectangular step-cut diamond with parallel long edges — the classic Art Deco side stone, straight-sided rather than angled, used in eternity bands, channel settings, and as accents flanking a center stone. Guru Diam stocks 263 Baguette diamonds on hand, calibrated and matched, IGI-gradable on request from our New York Diamond District desk.
What is a baguette cut diamond?
A baguette is a calibrated step-cut side stone: a narrow rectangle with two long edges running perfectly parallel to each other, faceted with broad, flat planes rather than brilliant faceting. That parallel-sided rectangle is the whole identity of the shape — it’s what makes baguettes stackable in straight, uninterrupted rows, which is why the cut became the signature side stone of Art Deco jewelry and remains the default choice for eternity bands and channel settings today.
The flat step-cut faceting keeps baguettes quiet rather than sparkly, the same design logic as other calibrated step-cut side stones: they’re meant to frame a center stone or build a clean linear pattern, not compete for attention.
Baguette vs. Tapered Baguette — parallel vs. angled sides
The most common sourcing mix-up with this shape is Baguette vs. Tapered Baguette. A straight baguette has parallel long edges, full stop — it’s a rectangle. A tapered baguette angles inward, wider at one end than the other, specifically so it can follow the curve of a ring shank as it narrows toward a center stone.
| Spec | Baguette (straight) | Tapered Baguette |
|---|---|---|
| Long edges | Parallel | Angled, narrowing toward one end |
| Best use | Eternity bands, straight channels, Art Deco lines | Following a shank taper toward a center stone |
| Set as | Uniform rows | Matched pairs or graduated angled sets |
| On-hand at Guru Diam | 263 | See our Tapered Baguette guide |
If the setting is a straight channel or a full eternity band, straight baguette is the correct shape. If the design needs side stones that narrow toward a center stone along a tapered shank, see our Tapered Baguette guide for that version.
Sourcing baguette diamonds wholesale
Baguette orders are a matching problem as much as a grading one — a full eternity band needs a run of baguettes that are uniform in width, length, and tone from end to end, and even a two-stone accent pair needs to match closely enough that neither stone reads as the odd one out. That depends on a supplier holding deep enough calibrated stock to pull a true matched run on demand.
Guru Diam calibrates and matches baguette diamonds in-house from our New York Diamond District desk and Los Angeles office — CVD lab-grown, IGI-gradable on request. In-stock pieces ship same-day from New York; a custom size or a full matched run outside current stock moves through CAD to a finished piece in 4–6 days.

FAQ
What is a baguette cut diamond? A baguette is a narrow, rectangular step-cut diamond with parallel long edges, used as a calibrated side stone in eternity bands, channel settings, and as accents flanking a center stone. The flat step-cut faceting gives a quiet, geometric look rather than heavy sparkle.
What’s the difference between a baguette and a tapered baguette? A straight baguette has parallel long edges and is used in uniform rows or straight channels. A tapered baguette angles inward, wider at one end than the other, so it can follow the taper of a ring shank toward a center stone — see our Tapered Baguette guide for that comparison in full.
How are baguette diamonds matched for an eternity band? Matching is done by width, length, and color/tone across the full run needed for the band, since the stones sit in an uninterrupted row. Deep on-hand calibrated inventory lets a supplier pull a genuinely matched set rather than combining stones from separate lots.
Are baguette diamonds certified? They’re sold as calibrated matched-set goods, IGI-gradable on request — the standard convention for calibrated side-stone shapes, while any center stone in the design is certified separately.
