Ignite your jewellery designs with this extraordinary Natural Seam Agate Kite Shape Cabochon from Pedra Gems — a captivating 27x17x4mm gemstone weighing 13.5 carats, combining a rare symmetrical kite silhouette with vivid, fiery natural colouring in bold red, orange-gold and deep earthy brown.
This stone has two remarkable qualities working together — a rare and distinctive shape, and a colour palette of exceptional natural intensity. The vivid crimson red and rich orange-gold banding swirl across the face of the stone with the warmth of a desert fire, grounded by deep, earthy brown tones that give the piece balance and depth.
✦ Stone Specifications:
• Shape: Kite (Symmetrical five-sided — flat top, angled shoulders, sharp bottom point)
• Dimensions: 27 x 17 x 4 mm
• Weight: 13.5 Carats
• Stone Type: Natural Seam Agate
• Colour: Vivid red, orange-gold & dark brown natural banding
• 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 & colour note: This is a one-of-a-kind stone — its kite silhouette, vivid colour combination and banding pattern are entirely unique and will never be replicated.
✦ About the Kite Shape:
The kite cut is a symmetrical five-sided silhouette — a flat straight top edge, two angled shoulder sides that widen outward before tapering inward to a sharp, decisive bottom point. Unlike the asymmetric shield cut, the kite is perfectly symmetrical — balanced left to right, creating a bold geometric form that is both architectural and dramatic.
The sharp lower point makes this shape exceptionally well suited for drop pendants, where the point hangs below and draws the eye downward with natural authority. The flat top edge provides a clean, stable base for wire wrapping and bezel settings, making this one of the most practical geometric shapes to work with despite its dramatic appearance.
✦ Perfect For:
• Statement drop pendant & necklace designs
• Wire wrapping — flat top & pointed bottom provide perfect anchor points
• Geometric & architectural jewellery designs
• Gothic & alternative jewellery collections
• Art deco inspired statement pieces
• Boho & fire-inspired jewellery designs
• Root chakra & sacral chakra crystal healing
• Collectors of rare shapes & vivid natural colour
✦ The Colour Story:
The red and orange-gold tones of this stone are among the most vivid natural colours found in Seam Agate. Created by iron oxide and chalcedony minerals within the rock seams, these fiery hues have taken millions of years to form — each band a chapter in the stone's geological history.
The US quarter dollar in the product photograph gives an instant, accurate sense of scale — at 27x17mm this is a confident mid-size kite stone, substantial enough to make a bold statement as a drop pendant without being oversized.
✦ 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 from Pedra Gems share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.
In crystal healing traditions, the fiery red and orange tones are associated with the root and sacral chakras — bringing passion, creativity, grounding and vital energy. This is a stone that energises as much as it captivates.
Order today from Pedra Gems and receive this exact hand-selected showpiece — fully polished, flat-backed, and ready to ignite your next creation.
Introducing one of the most visually dramatic stones in the Pedra Gems collection — our Natural Seam Agate Shield Cabochon, a breathtaking 31x14x4mm gemstone weighing 13.5 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.
✦ Stone Specifications:
• Shape: Shield (Kite Cut)
• Dimensions: 31x14x4 mm
• Weight: 13.5 Carats
• Stone Type: Natural Seam Agate
• Colour: Vivid red, orange, yellow, brown & silver-grey natural banding

• Shape note: This is a one-of-a-kind stone — its shield silhouette, colour combination and banding pattern are entirely unique and will never be replicated.
✦ 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

• Electroforming & copper wrap projects
• Solar plexus & root chakra crystal healing

✦ 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.
