Why You'll Love It

The Cyrus Tessera Diamond Band is the most geometrically precise piece in our collection — a 4.5mm wide solid 14K gold band engraved with a continuous checkerboard grid across its full surface, with a round brilliant lab-grown diamond flush-set at every intersection of the grid. The result is a band that is simultaneously a feat of goldsmithing and a feat of diamond setting: 59 individual round brilliant diamonds, each one set into its own circular seat at the corner where four checkerboard squares meet, creating a pattern that is as precise as a circuit board and as beautiful as a mosaic. The name Tessera comes from the Latin for the individual tile in a Roman mosaic — the smallest unit of a larger pattern, each one essential to the whole. In the Cyrus Tessera, each of the 59 diamonds is a tessera: a single point of light that contributes to a pattern that is only visible when you step back and see the whole.

The Checkerboard Pattern

The checkerboard engraving on the Cyrus Tessera is not applied to the surface — it is cut into it. Each square of the grid is a recessed panel, separated from its neighbors by a raised gold rail, creating a three-dimensional surface that catches light differently across its width. The alternating raised rails and recessed panels create a visual rhythm that is simultaneously bold and precise — a pattern that reads as a solid geometric field from a distance and reveals its individual squares and diamond intersections up close. The flush-set diamonds at each grid intersection sit at the raised corners where four squares meet, their table facets level with the top of the gold rails, creating a surface that is completely smooth to the touch while appearing to be covered in a continuous field of diamonds and gold geometry.

Why 59 Stones?

The number of diamonds in the Cyrus Tessera is determined by the geometry of the checkerboard grid: three rows of diamonds across the 4.5mm width of the band, spaced to align with the grid intersections, running continuously around the full circumference of the ring. The exact count — 59 stones — is a function of the ring size and the grid spacing, and may vary slightly by size to maintain consistent grid geometry. Every size receives the same three-row checkerboard pattern with diamonds at every intersection, ensuring consistent visual density regardless of size.

Why D–F Color?

In a flush bezel setting within a checkerboard grid, color grade is critical. Each diamond is surrounded by gold on all sides — the raised grid rails frame each stone completely — and any warmth in a lower-color stone would be amplified by the surrounding metal. D–F colorless diamonds ensure that each of the 59 station points reads as a pure, icy point of white light against the gold grid, creating the maximum contrast between the geometric gold pattern and the diamond intersections. In yellow gold, this contrast is most dramatic — warm metal, cool diamonds, precise geometry. In white gold, the diamonds and metal merge into a single field of cool precision. In rose gold, the warm blush metal gives the colorless diamonds a romantic, editorial quality.

Our Story

In our Queens atelier, the Cyrus Tessera was designed as the most technically demanding band we make. The checkerboard grid must be engraved with absolute precision — each square identical, each rail perfectly straight, each intersection perfectly aligned — before a single diamond can be set. Then each of the 59 diamonds must be set individually, each one burnished flush with the gold surface at its own intersection, each one perfectly level with its neighbors. The result is a band that takes longer to make than any other piece in our collection, and that shows: the Cyrus Tessera has a precision and a density that is immediately apparent to anyone who holds it. Named for the same Persian king as the Cyrus Station — the sun, the light-bearer — the Tessera is a band that carries 59 points of light in a pattern as old as the mosaic and as modern as the grid.
