Oval Shape

Discover an autumn garden frozen in crystal with our Garden Quartz Drill & Fill Cabochon from Pedra Gems — a captivating 28x17x9mm gemstone weighing 34 carats, featuring vivid emerald green, golden amber, burnt orange and ruby red mineral fill suspended beneath an exceptionally deep dome of clear quartz.

This stone is created using the specialised drill and fill technique — a cavity hand-drilled into clear quartz rough, then filled with natural crystalline minerals in a rich, multicoloured palette. At a striking 9mm dome height — the deepest in our garden quartz collection — the magnifying effect of the clear quartz is dramatically enhanced, making the colour beneath appear to glow and shift with extraordinary depth and dimension.

✦ Why This Stone is Exceptional:
At 9mm this cabochon has the deepest dome in the Pedra Gems garden quartz collection — noticeably taller than our 31×23×7mm piece. That extra height creates an even more dramatic magnifying lens effect over the mineral fill, giving the colours an almost three-dimensional, glowing quality that catches every light source.

The colour palette of vivid green, gold, orange and red is reminiscent of autumn foliage — warm, rich and full of natural energy. Combined with the deep dome, this stone has a genuinely luminous, almost glowing presence that smaller or flatter drill and fill pieces cannot achieve.

At 34 carats and 28x17mm this is a substantial, eye-catching stone with real presence in the hand. Every drill and fill stone is completely unique — no two mineral fills will ever be identical, making this piece a genuine one-of-a-kind treasure.

✦ About Garden Quartz:
"Garden quartz" traditionally refers to quartz crystals containing natural mineral inclusions that resemble miniature garden or landscape scenes when viewed from above. The drill and fill technique recreates this captivating effect by intentionally placing mineral material into a prepared cavity within clear quartz — offering a curated, vivid colour palette while honouring the traditional garden quartz aesthetic.

Clear quartz is one of the most significant crystals in mineral healing traditions — associated with clarity, amplification of energy, and spiritual connection. The rich, warm mineral colours within this particular stone add a grounded, vital, autumnal energy.

This one-of-a-kind round Garden Quartz cabochon features a hand-drilled cavity filled with crushed mixed gemstone chips in vibrant green tones, creating a stunning druzy-style centerpiece. Set against the clear quartz dome, the crushed stone inlay catches light beautifully, making this a striking focal piece for handmade jewelry.

Dimensions: 21mm x 21mm x 8mm (approx.)
Weight: 27ct (approx.)
Shape: Round Cabochon

Material Note: This is a composite cabochon — a natural quartz base that has been drilled and filled with crushed mixed gemstone material (multiple stone types), then sealed with a clear dome. This technique creates a unique, one-of-a-kind decorative effect not found in single-origin natural stones.

Please note: Measurements may vary by ±0.5mm and weight by ±0.5ct due to the natural, handcrafted nature of this piece. Photos are taken to accurately represent the actual stone you will receive.

Ideal for rings, pendants, wire wrapping, and other custom jewelry designs. Sold as a single piece.

Step into a tiny captured world with our Garden Quartz Drill & Fill Cabochon from Pedra Gems — a mesmerising 31x23x7mm gemstone weighing 39 carats, featuring a natural mineral cluster suspended within crystal-clear quartz like a miniature landscape frozen in time.

This stone is created using the rare drill and fill technique — a small cavity is hand-drilled into clear quartz rough, then filled with natural crystalline minerals, capturing flashes of rose pink, deep teal-green, golden bronze and shimmering black in a single breathtaking formation. The high domed top magnifies the inclusion beautifully, creating depth and dimension that shifts and sparkles as the stone moves in light.

✦ Stone Specifications:
• Shape: Free form oval
• Dimensions: 31 x 23 x 7 mm
• Weight: 39 Carats
• Stone Type: Garden Quartz — drill and fill technique
• Cut: Cabochon, high dome
• Finish: High-polish, smooth surface
• Back: Flat, ready to set
• Please note: This stone is created using the drill and fill technique — a cavity is hand-drilled into clear quartz and filled with natural mineral material. This is fully disclosed for buyer transparency. As a hand-crafted piece, size may vary slightly and the mineral pattern is entirely unique to this individual stone.

✦ Perfect For:
• Statement pendant & focal point necklace designs
• Wire wrapping — high dome provides excellent showcase
• Collector & display pieces
• Crystal healing & meditation work
• Boho & artisan jewellery collections
• Unique gifts for mineral & crystal collectors
• Bespoke commission jewellery centrepiece

✦ Why This Stone is Exceptional:
The drill and fill technique is a specialised lapidary art form that takes considerable skill to execute well. The cavity must be drilled with precision to avoid cracking the surrounding quartz, then carefully filled with mineral material so that when polished, the inclusion appears to float naturally within the crystal — as if nature herself placed a tiny garden inside the stone.

At 7mm this is a high dome cabochon — taller than most standard cuts — specifically chosen to maximise the magnifying effect of the clear quartz over the mineral inclusion. Looking into the stone is like looking into a miniature cave or garden scene, with colour and texture that shifts depending on the angle and light source.

At 39 carats and 31x23mm this is a substantial, eye-catching stone — large enough to be the undeniable focal point of any jewellery piece. Every drill and fill stone is completely unique; no two mineral inclusions will ever be identical.

✦ About Garden Quartz:
"Garden quartz" traditionally refers to quartz crystals containing natural mineral inclusions that resemble miniature garden or landscape scenes when viewed from above. The drill and fill technique recreates this captivating effect by intentionally placing mineral material into a prepared cavity within clear quartz, offering a way to enjoy the garden quartz aesthetic with a curated, vivid colour palette.

Clear quartz itself is one of the most significant crystals in mineral healing traditions — associated with clarity, amplification of energy, and spiritual connection. Combined with the rich mineral inclusion, this stone carries a particularly grounded yet luminous energy.

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.

✦ Stone Specifications:
• Shape: Oval
• Dimensions: 34x22x6 mm
• Weight: 35.5 Carats
• Stone Type: Natural Seam Agate
• Cut: Cabochon (flat back, deep 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.

✦ Perfect For:
• Large statement brooch & pin centrepiece
• Bespoke commission jewellery — ring, cuff, pendant, collar
• Statement cuff bracelet focal stone
• Large wire wrapping & oversized bezel settings
• Electroforming & large copper wrap projects
• Display & museum-quality collector piece
• Crystal healing — the largest healing stone in the Pedra Gems range
• Interior design & decorative gemstone display
• Investment-grade natural gemstone collection

✦ Scale & Presence:
To appreciate the scale of this stone — at 34mm it is larger than a standard US quarter dollar (22mm) in both dimensions. In a brooch setting it would command the full focal point of any outfit. In a wire-wrapped pendant it would be a dramatic, statement piece that draws attention from across a room.

At 35.5 carats this is almost four times the weight of our standard 35.5ct ovals — the sheer mass of natural Seam Agate material in this stone represents exceptional geological quality. Stones of this size and weight with clean, polished surfaces and rich natural banding are rare and increasingly sought after by serious collectors.

The 6mm deep dome adds a spectacular visual dimension — at 34mm wide the dome creates a generous, rounded profile with light play across the polished surface that shifts and changes with every movement and every light source.

✦ Investment & Rarity:
Large natural cabochons of this quality — 35.5 carats, 34x22mm, deep dome, fully polished — are genuinely rare. As natural gemstone rough of this quality becomes increasingly scarce, large premium cabochons like this one are recognised by serious collectors as both beautiful objects and sound natural gemstone investments.

✦ 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 from Pedra Gems share the same pattern, colour, or flow — every cabochon is a completely unique piece of natural art.

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