Seam Agate Diamond Shape Cabochon 35x24mm 27ct – Pedra Gems

Discover one of the rarest and most dramatic shapes in the Pedra Gems collection — our Natural Seam Agate Diamond Shape Cabochon, a striking 35x24x5mm gemstone weighing 27 carats, cut into a perfectly symmetrical diamond silhouette with warm orange-gold and red-brown banding punctuated by beautiful white and grey translucent areas.

The diamond shape — also known as the lozenge or rhombus cut — features four straight sides of equal length meeting at sharp points at the top and bottom, with the stone widest across its middle. It is a shape of perfect geometric symmetry — bold, architectural, and deeply striking. At 35x24mm this is a large, commanding diamond cabochon with exceptional visual presence.

✦ About the Diamond Shape:
The diamond or lozenge cut is one of the most powerful geometric shapes available in cabochon form. Its perfect four-sided symmetry creates a strong, balanced composition — the sharp top point draws the eye upward while the sharp bottom point creates natural downward movement, making this shape exceptionally dynamic in pendant designs.

Unlike a square rotated 45°, the natural lozenge proportions of this stone at 35x24mm are elongated — taller than wide — giving it a graceful, vertically oriented diamond form that hangs with particular elegance as a drop pendant. The two pointed tips provide strong natural anchor points for wire wrapping at both top and bottom, creating perfectly symmetrical wrapping opportunities.

✦ The Colour Story:
This stone carries three distinct colour elements that work in beautiful harmony. The warm orange-gold tones glow with the richness of autumn leaves and desert sand. The deep red-brown areas add earthy, grounded depth. The white and grey translucent sections catch light differently to the opaque areas, creating a subtle inner glow effect that adds mystery and dimension to the stone's natural character.

✦ Size Reference:
The US quarter dollar in the product photograph gives an accurate sense of scale. At 35x24mm this diamond cabochon is significantly larger than the coin — a bold, substantial stone with commanding presence on the neckline.
