Freeform Shape

Introducing one of the most visually dramatic stones in the Pedra Gems collection — our Natural Seam Agate Shield Cabochon, a breathtaking 38x16x4mm gemstone weighing 19.5 carats, combining a rare shield silhouette with an extraordinary explosion of vivid red, orange, yellow and brown natural banding.

This stone stops you in your tracks. The fiery interplay of deep crimson red, warm burnt orange, golden yellow and rich earthy brown — punctuated by mysterious silver-grey areas — creates a natural composition of rare intensity and beauty. No two stones in the world carry this exact combination of colour, pattern, and form.

✦ About the Shield Shape:
The shield cut — also known as the kite cut — is defined by two straight sides that meet at a sharp upper point, one gently curved side, and a sharp lower point. This asymmetric, angular silhouette is one of the rarest and most dramatic shapes in the cabochon world — bold, directional, and deeply distinctive.

At 38mm tall this is a long, elongated shield with a strong vertical presence. The sharp top point draws the eye upward while the curved lower section flows elegantly into the lower tip — creating a stone with genuine visual tension and movement.

✦ Perfect For:
• Show-stopping statement pendant & necklace designs
• Wire wrapping — the two pointed ends provide strong natural anchor points
• Freeform & artistic jewellery collections
• Boho & fire-inspired jewellery designs
• Electroforming & copper wrap projects
• Solar plexus & root chakra crystal healing
• Collectors of rare shapes & vivid natural colour
• Bespoke commission jewellery centrepiece

✦ The Colour Story:
The red tones in this stone are created by iron oxide inclusions within the agate — the same mineral that colours terracotta, rust, and desert sandstone. The golden yellow and burnt orange layers are rich in chalcedony and iron minerals, creating warm, glowing bands that seem to radiate heat. The silver-grey areas add a beautiful cooling contrast — like storm clouds moving across a desert sunset.

This is a stone that tells a geological story millions of years in the making.

✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing richly layered banding in warm, earthy tones. No two stones share the same pattern, colour, or flow.

In crystal healing traditions, the fiery red and orange tones of this stone are associated with the root and sacral chakras — bringing energy, passion, creativity, and grounding strength. The golden yellow tones connect to the solar plexus chakra, amplifying confidence and personal power.

Experience the beauty of nature's own geometry with our Natural Seam Agate Freeform Rounded Corner Triangle Cabochon — a captivating 30x14x5mm gemstone weighing 16.5 carats, shaped into an elongated triangular silhouette where every corner flows into a soft, organic curve rather than a sharp point.

This stone occupies a wonderful creative space between geometric and organic. Its three-sided triangular form gives it strong directional energy and visual structure — but the rounded corners soften every angle into a gentle, flowing curve that feels warm, natural, and deeply wearable. It is a triangle that has been touched by nature.

✦ Stone Specifications:
• Shape: Freeform (Rounded Corner Triangle)
• Dimensions: 30 x 14 x 5 mm
• Weight: 16.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Please note: As these are natural gemstones, size and weight may vary slightly. Dimensions may differ by ±0.5mm and weight by ±0.5ct from the listed measurements.
• Shape note: Freeform stones are unique by nature — the exact curvature of the corners, banding pattern, and silhouette of this stone are individual to this piece and will not be replicated in any other.

✦ Perfect For:
• Long drop pendant & statement necklace designs
• Wire wrapping — rounded corners wrap smoothly with no sharp pressure points
• Boho & nature-inspired jewellery collections
• Electroforming & copper wrap projects
• Focal stone for macramé & fibre art
• Modern geometric jewellery with an organic twist
• Crystal healing & energy work
• Collectors of rare organic geometric shapes

✦ Why This Rounded Corner Triangle?
The 30×14mm proportions give this stone a dramatically elongated triangular form — nearly 2.2:1 length-to-width ratio — making it one of your most slender and directional triangle shapes. Wide across the top with a gently tapering base, it creates a strong sense of downward movement ideal for long drop pendants that draw the eye elegantly down the neckline.

The key distinction from your sharp-cornered triangles is the rounded corners. Where sharp corners create angular, geometric tension, rounded corners soften that energy — creating a shape that feels simultaneously structured and organic. This makes the stone more versatile across jewellery styles, equally at home in a boho wire-wrapped pendant and a modern minimalist setting.

The rounded corners are also a practical advantage for wire wrappers. Unlike sharp-cornered triangles that require tight corner wraps, the gentle curves allow wire to flow continuously and smoothly around the entire perimeter — producing naturally graceful, fluid wrapping lines with no awkward angles to navigate.

At 30mm long this is one of your longest triangle-family stones — a bold, dramatic drop pendant stone with serious visual presence. The 5mm dome adds excellent depth and rich light play, making the natural Seam Agate banding glow beautifully across the elongated face.

✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing its characteristic richly layered banding in warm, earthy tones. No two stones share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.

The flowing organic banding of Seam Agate pairs beautifully with the softly rounded triangular form — both sharing the same language of gentle curves and natural movement.

Celebrated for its grounding and stabilising energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide.

Order today and receive this exact hand-selected gemstone — its rounded corners, elongated silhouette, and natural banding are entirely one of a kind and will never be repeated.

This is not a precision geometric triangle. It is a free form cabochon that nature and the cutter's hand have shaped into a gentle, organic triangle-like form — wide at one end, tapering toward the other, with all edges flowing in soft curves rather than hard angles. The result is a stone that feels simultaneously architectural and natural — grounded and earthy, yet boldly shaped.

✦ Why Rounded Triangle?
The rounded triangle is one of the most visually compelling shapes in the freeform cabochon world. Sharp-cornered triangles can look harsh and geometric — but when all edges are softly rounded, the stone takes on a warm, organic character that is both distinctive and deeply wearable.

At 36mm long and just 16mm wide, this is a dramatically elongated stone — one of the longest in our collection. Its slender footprint makes it ideal for long drop pendants that create vertical movement on the neckline. The low 6mm dome keeps the overall piece sleek and elegant despite the generous length.

The soft rounded edges are also a practical advantage for wire wrapping — smooth curves allow wire to travel cleanly along the perimeter without catching or creating uncomfortable pressure points against the skin.

Discover a truly rare natural treasure — our Natural Seam Agate Free Form Cabochon, a captivating 28x14x5mm gemstone weighing 15 carats, featuring a remarkable partial translucency on one side that allows light to pass through like a glowing window.

This is not a common feature. Most Seam Agate cabochons are fully opaque — but this individual stone carries a naturally translucent section on one side where the agate thins and clears, creating a beautiful interplay of light and shadow across the stone's surface. Hold it to the light and watch it glow.

✦ Stone Specifications:

• Electroforming & copper wrap projects
• Boho, artisan & nature-inspired jewellery
• Crystal healing & light energy work
• Collectors of rare & unusual natural gemstones

✦ The Translucency Feature:
Partial translucency in Seam Agate occurs naturally where silica-rich layers within the stone are thinner or purer in composition. This creates a softly glowing section that contrasts with the opaque banded areas — a characteristic highly prized by collectors and jewellery designers who want a stone with depth, mystery, and light play that no fully opaque stone can offer.

When set in a wire-wrapped pendant and worn, light from the environment naturally backlights the translucent section throughout the day — creating a living, ever-changing glow.

✦ About Seam Agate:
Seam Agate is a natural chalcedony formed within rock seams and fissures, producing richly layered banding in warm, earthy tones. No two stones share the same pattern, colour, or translucency — every cabochon is a completely unique piece of natural art.
