Shape is the outline you see from above; cut is the geometry of facets beneath it. A short, visual guide to the classic center-stone shapes — and the straight-edge accent cuts Bichachi is known for.
The benchmark of brilliance. Fifty-eight precisely angled facets engineered to return the maximum light — the most studied and most enduring cut of all.
A square face-up with sharp, uncut corners over a pyramidal pavilion. Brilliant faceting delivers fire close to a round in a crisp, modern silhouette.
A square-to-rectangular outline with gently rounded corners and large, open facets. A soft, pillow-like silhouette with a warm, romantic glow.
An elongated brilliant carrying the fire of a round in a flattering, finger-lengthening outline. Reads larger than its weight and flatters the hand.
A rectangular step cut with cropped corners and long, parallel facets. Prizes clarity and a hall-of-mirrors transparency over flash and sparkle.
A teardrop hybrid of round and marquise — one softly rounded end, one tapered point. Brilliant faceted, elegant, and quietly elongating on the hand.
A long, boat-shaped brilliant tapering to a point at each end. Spreads its weight to maximise face-up size and the illusion of length.
Trimmed corners with full brilliant faceting — the liveliness of a round in a rectangular or square outline. Bright, durable, and versatile.
A square step cut with deep, dramatic corners and concentric facets that draw the eye inward — the signature windmill, hall-of-mirrors effect.
A romantic brilliant — essentially a pear with a cleft. It lives or dies on symmetry: two perfectly matched lobes and a crisp, even point.
Beyond the center stone — the baguettes, trapezoids and half moons that flank it. Calibrated, matched, and fine-made: the discipline the Bichachi house was built on.
A slim, elongated rectangle with straight, parallel step facets and squared corners. The classic side stone — clean, architectural, made for channel and pavé.
A baguette with gently sloping long sides that narrow toward one end. Step-cut and directional — built to lead the eye in toward a center stone.
A four-sided stone with one wide and one narrow parallel edge, faceted in clean concentric steps. A crisp, quiet geometric flank for a center stone.
The same tapered four-sided outline, faceted brilliant-style for fire rather than quiet steps. Side-stone sparkle that keeps pace with a brilliant center.
A half-circle with one straight edge and one curved, brilliant-faceted for liveliness. A flowing companion that hugs a center stone or a round.
Two stones of the same shape can look worlds apart. The difference is the make — the precision of the facets, the symmetry, and the polish. That straight-edge and fancy-cut precision is exactly where the Bichachi house has spent thirty years.
Shape sets the silhouette. To read a stone fully, you also need its place on the color and clarity scales — the next chapter of the guide.
