✦ Why Marquise Shape?
The marquise is one of the most flattering shapes in all of jewellery making. Its 26x11mm proportions produce a length-to-width ratio of nearly 2.4:1 — a dramatic, elongated form that creates a strong visual line in any design.

When set as a ring stone, the marquise shape visually elongates the finger — a well-known effect that has made it a perennial favourite in engagement and statement ring design. As a pendant, the double-pointed form creates natural movement and a dynamic, directional energy that oval and round stones simply cannot match.

The two pointed tips are a practical advantage for wire wrappers — each tip provides a natural anchor point for wrapping, creating a symmetrical, balanced design with structural integrity at both ends.

At 25x10 alternative jewellery stone. 4.5 carats and 2mm dome, this is a substantial and visually commanding stone — full of rich natural Seam Agate banding across its generous surface area.

✦ 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 pair beautifully with sterling silver, gold-filled, and copper wire settings.
