Pair of Antique Single Stripe Chung Dzi, Bicone Form, 15.7×11.5mm & 15.8×11.5mm, Warm Dark Brown, Greying Stripe (At-081123-1SPair)

We never retouch our photos. What you see is exactly what you will receive.

The central stripe on each of these beads is not white and not grey — it is caught mid-way between the two, and the photographs show you exactly where in that journey it currently sits.

That transition is not a flaw. It is what three to five centuries of mineral chemistry does to a calcification band deposited in the central zone of a natural agate bead. The stripe began as a bright mineral accumulation; it has been slowly absorbing the chemistry of the agate and the environment around it, and the photographs show it in its current state: a wide, granular, cool grey-white band that reads differently in different light, sometimes closer to cream, sometimes clearly grey. It will continue to change. What you see is a bead in process — which is what every genuine antique piece is.

The form is a clean bicone: two equal conical halves tapering from the equatorial stripe band to small, well-centred drill holes at each pole. This is the classic Chung dzi single-stripe body, and in this pair the proportions are almost perfectly matched — 15.7×11.5mm and 15.8×11.5mm, a difference of a single tenth of a millimetre in length. At nearly 16mm in diameter against just under 16mm in length, these are almost spherical in overall silhouette, with the bicone taper only becoming apparent when the beads are viewed from the end.

The two beads are not identical in ground colour, and that difference is part of what makes the pair visually coherent rather than repetitive. Bead A carries a warm reddish-brown on its upper cone and a deep, substantially darker tone on its lower cone — the colour shift is visible in Image 1 and confirmed from the end views in Images 2 and 3. The upper shoulder of Bead A also shows a faint blue-grey sheen in the photographs, a phenomenon occasionally observed in ancient and antique agate where the internal light refraction through the stone produces a cool optical overtone at the surface. Bead B is more tonally uniform across both cones — a consistent warm dark reddish-brown throughout, with natural agate banding faintly visible through the body in the end-face photographs. Both beads carry a high-gloss surface on their brown agate zones, contrasting directly with the matte-granular texture of the greying stripe band. This surface contrast — gloss against matte, brown against grey-white — is what makes the single-stripe Chung dzi composition legible from any distance.

The stripe on each bead occupies the full equatorial width — a wide central band rather than a narrow accent, giving each bead a substantial visual weight at its centre that the tapering cones then resolve at both ends. No bloodspot inclusions are detected in any photograph. No chips, cracks, medicine digs, or surface damage are present.

In this collection, the natural calcification single-stripe category includes At-020726-Chung — a short wide fusiform with a single dark band on an ivory-cream ground — and the ancient bicone pair Ac-061526-1SPair, where one bead is pale grey-white and one is deep dark grey-brown. At-081123-1SPair differs from both: where At-020726-Chung is a single bead with a dark band on a light ground, these two beads have a light band on a dark ground, and the pair format gives them a doubled presence neither individual bead could produce alone. Where Ac-061526-1SPair presents as maximum tonal contrast between the two beads, this antique pair reads as tonal variation within the same warm-brown family — more intimate, more closely matched.

The Single Stripe Chung Dzi Motif 單條紋瓊珠

The single stripe Chung dzi (單條紋瓊珠, dān tiáowén qióng zhū) is one of the most reduced forms in the entire dzi tradition — a single band crossing the equator of the bead, dividing it into two equal halves. In Tibetan and broader Himalayan usage, this division is understood as the boundary between opposites: above and below, heaven and earth, visible and invisible, manifest and unmanifest. The single stripe does not elaborate or decorate — it simply marks the place where two things meet. This austerity is its strength. Chung dzi of this type have been used as anchor beads in multi-bead compositions, as meditation objects whose simplicity makes them easier to hold in sustained attention, and as protective pieces whose power is understood to reside precisely in what they do not say. A bead that holds one line holds a complete statement.
