Oval Shape

Presenting the crown jewel of the Pedra Gems collection — our Natural Seam Agate XL Oval Cabochon, a breathtaking 34x22mm gemstone weighing a full  35.5carats. This is the largest, heaviest, and most magnificent stone we offer — a once-in-a-collection natural treasure of extraordinary scale and beauty.

At 34mm this oval is genuinely large — roughly the size of a large walnut and larger than most standard brooch blanks. The near 1.5:1 length-to-width ratio produces a beautifully balanced, full-bodied oval that displays the natural Seam Agate banding across a canvas of exceptional scale. Every layer, every band, every colour variation is visible in generous, sweeping detail that smaller stones simply cannot reveal.

The 6mm dome rises confidently above the surface, adding extraordinary visual depth and a rich, three-dimensional quality that makes the banding appear to glow from within. At 35.5 carats the stone carries a weight and substance in the hand that immediately communicates premium natural quality to any experienced collector or jeweller.

Discover generous natural beauty from Pedra Gems — our Natural Seam Agate Oval Cabochon, a beautifully rounded 25x18x5mm gemstone weighing 20 carats, cut into a wide, full-bodied oval silhouette that showcases the rich natural banding of Seam Agate across an exceptional face area.

At 25x18mm this oval has a near 1.4:1 length-to-width ratio — one of the widest and most rounded oval proportions in the Pedra Gems collection. This generous width creates a stone with maximum face area, displaying the natural banding of the Seam Agate in all its layered glory. Not an elongated oval, not a narrow stone — this is a full, confident, beautifully rounded gem.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 25 x 18 x 5 mm
• Weight: 20 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.

• Oval bezel ring settings — wide ovals make exceptional ring centrepieces
• Wire wrapping & bezel settings
• Bridal & occasion jewellery making
• Boho & artisan jewellery collections
• Everyday wearable statement pendant
• Crystal healing & grounding energy work

✦ Why This Wide Oval?
The 25x18mm proportions give this stone a wide, rounded form that sits between a classic oval and a near-circle in character — full, generous, and visually rich. That generous width means more natural agate banding is visible across the face of the stone than any of our narrower oval cuts.

For ring settings, a wider oval like this is particularly flattering — the broad face elongates and widens the appearance of the finger beautifully, creating a statement ring that draws attention from across a room. For pendant settings, the wide face creates a rich, substantial centrepiece that wears confidently on the neckline.

The 5mm dome adds excellent depth and warm light play across the polished surface — a classic dome height that gives this stone beautiful visual presence from every angle without being so high as to look bulky.

At 20 carats this is a premium stone with genuine substance. The weight combined with the wide face makes this one of the most satisfying and impressive natural cabochons in the Pedra Gems oval range — a stone that jewellers and collectors will immediately appreciate as exceptional quality.

Discover timeless natural elegance with our Natural Seam Agate Oval Cabochon — a beautifully proportioned 29x20x6mm gemstone weighing 30.5 carats, combining classic oval form with a sleek low-profile dome that makes it one of the most versatile and wearable stones in our collection.

At 29x20x6 mm this oval has a near 1.6:1 length-to-width ratio — widely regarded among jewellers as one of the most flattering and universally appealing oval proportions available. Not too elongated, not too wide, this stone sits in the sweet spot that works beautifully in every setting style from classic fine jewellery to boho wire wrapping.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 29x20x6 mm
• Weight: 30.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, low dome)
• 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.

✦ Perfect For:
• Classic oval pendant & necklace designs
• Oval bezel ring settings
• Wire wrapping & bezel settings
• Everyday wearable pendant designs
• Flush & low-profile bezel settings
• Bridal & occasion jewellery making
• Boho & minimalist jewellery styles
• Crystal healing & grounding energy work

✦ Why This Oval?
Two features make this stone stand out — its classic proportions and its low 4mm dome.

The 29x20mm proportions produce a near 1.6:1 ratio — the golden ratio of oval cabochons. This proportion is the most universally flattering for oval stones because it creates a shape that reads clearly as an oval without looking elongated or stubby. It suits standard oval bezel settings, ring mounts, and pendant blanks that buyers already have in their collection.

The 4mm dome is lower than most cabochons of this size, which carries three practical advantages. For everyday pendant wear, a lower dome sits closer to the skin and catches on clothing less. For bezel settings, lower dome walls are needed making setting easier and the finished piece sleeker. For wire wrapping, wire travels more smoothly and evenly across a flatter surface producing cleaner wrapping lines.

At 30.5 carats this is a well-weighted stone — substantial enough to feel premium as a pendant centrepiece while remaining perfectly comfortable for daily wear. A reliable, beautiful, endlessly versatile natural gemstone.

✦ 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.

Experience the rare magic of a glowing natural gemstone with our Natural Seam Agate Oval Cabochon — a captivating 22x13x5mm stone weighing 13.5 carats, featuring a beautiful partial translucency that allows natural light to pass through and glow warmly from within.

Hold this stone to the light and watch it come alive. The translucent section glows with a soft, warm inner light — a completely natural phenomenon that occurs where silica-rich layers within the agate thin and clear, creating a living interplay of light and shadow across the stone's surface. This is not a common feature in Seam Agate and makes this stone truly one of a kind.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 22 x 13 x 5 mm
• Weight: 13.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, domed top)
• Finish: High-polish, smooth surface
• Special Feature: Partially translucent — natural light passes through
• 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.
• Translucency note: The glowing translucent area is a natural characteristic unique to this individual stone and will not be replicated in any other piece.

✦ Perfect For:
• Wire wrapping — translucent area glows beautifully when pendant is worn
• Backlit & statement pendant necklace designs
• Standard oval bezel & pendant settings
• Resin casting — stone glows within resin under light
• Crystal healing & light energy work
• Boho & artisan jewellery collections
• Collectors of rare & unusual natural gemstones

✦ What Makes This Stone Special:
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 beautifully with the opaque banded areas — a quality highly prized by collectors and jewellery designers who want a stone with depth, mystery, and living light play.

At 22x13mm this is a versatile mid-size oval — slender enough to sit elegantly on the neckline yet large enough to showcase the translucent glow with impact. The standard 5mm dome gives the stone excellent depth and rich light play across the polished surface, enhancing the glowing translucent effect beautifully.

When set in a wire-wrapped pendant and worn, natural light from the environment backlights the translucent section throughout the day — creating a living, ever-changing glow that no opaque stone can replicate.

✦ Photography Tip:
Photograph this stone held up to a bright window or lamp so light shines through the translucent section. This backlit glow shot will be your most powerful listing image — it instantly communicates what makes this stone rare and will stop buyers mid-scroll. Add "See photo 2 for the glowing effect" in your first description line.

✦ 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.

Celebrated for its grounding and calming energy, Seam Agate is a favourite among crystal practitioners and artisan jewellers worldwide.

Order today and receive this exact hand-selected gemstone — its translucency, banding, and character are entirely one of a kind and will never be repeated.

Discover one of nature's rarest gifts — our Natural Seam Agate Oval Cabochon, a captivating 29x17x3mm gemstone weighing 14.5 carats, combining two exceptional features in a single stone: a rare partial translucency that allows light to glow through, and an elegant low 3mm dome profile that makes it one of the most versatile and wearable stones in our collection.

Hold this stone to the light and watch it transform — the translucent section glows warmly, creating a living interplay of light and shadow across the natural agate banding. This is not a common feature. Most Seam Agate cabochons are fully opaque — this stone carries a naturally translucent area where silica-rich layers thin and clear, producing a soft inner glow that changes with the light throughout the day.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 29 x 17 x 3 mm
• Weight: 14.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, low dome)
• Finish: High-polish, smooth surface
• Special Feature: Partially translucent — natural light passes through
• 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.
• Translucency note: The glowing translucent area is a natural characteristic unique to this individual stone and will not be replicated in any other piece.

✦ Perfect For:
• Backlit pendant & statement necklace designs
• Wire wrapping — translucent area glows beautifully when worn
• Flush & low-profile bezel settings
• Resin casting & resin art projects — stone glows within resin under light
• Lightweight everyday pendant designs
• Macramé & fibre art focal stones
• Crystal healing & light energy work
• Collectors of rare & unusual natural gemstones

✦ Two Rare Features in One Stone:
This cabochon is exceptional for two independent reasons — and the combination of both in a single stone makes it truly one of a kind.

The partial translucency creates a glowing window effect when backlit — a feature highly prized by collectors and jewellery designers who want a stone with depth, mystery, and living light play that no fully opaque stone can offer.

The 3mm low dome means this stone sits closer to the skin than any standard cabochon, making it ideal for flush bezel settings where a lower profile is required. For wire wrapping, the flat surface means wire travels cleanly and evenly. For resin casting, the low height means the stone can be fully embedded in a shallow resin layer while still showing its full face.

At 29x17mm this is a generous oval footprint — large enough to be a bold centrepiece pendant — while the 3mm dome keeps the overall piece feeling refined and lightweight rather than chunky.

✦ Photography Tip:
Make sure to photograph this stone held up to a window or lamp so buyers can see the translucent glow. This backlit photo will be your most powerful listing image and your biggest conversion driver.

✦ Why This Stone Stands Out:
At 30x22mm and 32.5 carats, this is a large, commanding oval cabochon with exceptional visual impact. The 6mm dome — deeper than most standard cabochons — gives the stone a rich, full profile that catches light beautifully from every angle.

The combination of red, yellow, and white is particularly rare and striking in Seam Agate. Red tones in agate are created by iron oxide inclusions, giving each stone its warm, fiery character. The contrast against white and golden yellow bands creates a natural composition that no designer could replicate.

✦ Colour & Energy:
In crystal healing traditions, the red and yellow tones of this agate are associated with the root and solar plexus chakras — bringing energy, confidence, and vitality. White banding adds a balancing clarity to the stone's energetic profile.
