Small Seam Agate Triangle Cabochon 15x13mm 5ct – Natural Gemstone

Bring bold geometric character to your everyday jewellery with our Natural Seam Agate Small Triangular Cabochon — a charming 15x13x4mm gemstone weighing just 5 carats, cut into a compact triangular silhouette that delivers modern, geometric style in a dainty, lightweight package.

At 15x13mm this is a small, near-equilateral triangle — compact, balanced, and beautifully proportioned. The natural Seam Agate banding flows across the three-sided face with striking effect, making this petite stone far more visually interesting than a plain round or oval of the same size.

✦ Why This Small Triangle?
At just 15x13mm and 5 carats, this is one of the lightest stones in our collection — making it an excellent choice for earrings where comfort and wearability are essential. Two of these stones together would make a beautifully matched pair of geometric triangle studs — lightweight enough for all-day wear, distinctive enough to draw compliments.

The near-equilateral proportions (15mm wide x 13mm tall) give this triangle a compact, balanced silhouette — not elongated or skewed, but a clean, confident three-sided form that sits neatly in standard triangular bezel settings.

The 4mm dome gives the stone just enough height for visual presence and natural depth without making it too high-profile for everyday stud earring wear.

The contrast between the organic, flowing natural agate banding and the sharp geometric triangle silhouette creates a uniquely compelling visual — earthy and bold, natural and designed, all in one small but powerful stone.

✦ 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.

Celebrated for its grounding and stabilising energy, Seam Agate is beloved by crystal practitioners and artisan jewellers worldwide. Its warm earthy tones complement sterling silver, gold-filled, and copper settings beautifully.
