About the Custom 'No. 21' Family Crest

The Custom 'No. 21' Family Crest is a one-of-one solid gold signet ring, cast from solid Australian gold on the Gold Coast. 14mm wide face, 14mm tall, full sized signet proportions. 1.8mm shank, 3mm face thickness. Your family crest is designed from scratch and cast directly into the gold. Not engraved. Not applied after the fact. It's part of the ring.

The images shown are examples of crests we've previously created. Your ring will feature a completely custom design - developed with you from initial consultation through to final approval. Whether you're working from an existing family crest or building one from scratch, the process is collaborative. You decide what goes on the face. We make it work in metal.

Once the design is finalised, the crest is modelled in 3D CAD and cast directly into solid gold. The result is a single piece - crest and ring, one continuous form. No separate components. No surface treatment. Just gold, shaped to your specification.

The gold is solid all the way through - no plated surface, no hollow core, no base metal underneath. Five years from now, ten years from now, it's the same ring. That's what solid gold means.

Most popular at Cavetta - 14ct gold. The balance of rich colour and everyday durability.

Our Difference

This isn't a mass-produced signet with a shallow laser-etched logo.

Because your crest is cast directly into the ring, not engraved onto the surface afterwards - the detail is part of the gold itself. Deep, crisp, and made to hold for generations.

Thius is the ring your grandkids will argue over.

How It Works:

We work with you to get the initial ideas of your crest started, from there we build a photorealistic 3D render, your exact gold, your exact crest and every detail visible exactly as it will be cast.

You review it. You request any changes. We refine until it's perfect. Only once you've given your written approval does a single gram of gold get poured.

Most customers tell us the CAD is the moment it stops feeling like an order and starts feeling like their ring.

Nothing is cast until you say yes.

This Is Not How Most Rings Are Made.

Most gold rings are hollow at the core or on the inside of the band, a thin shell of gold over a base metal form.

It keeps costs low, speeds production, and is completely invisible to the buyer until the gold wears through years later.

Cavetta rings contain no base metal. No hollow core. No plated surface.

The gold you see on the outside is the same gold that runs through to the bore.

This makes every ring heavier, more durable, and fundamentally different from almost everything else in the market.

  • Sustainably Mined Australian Gold

    Every ring is solid gold all the way through from the outer surface to the inner bore.

    No hollow backings or plated finishes.

    Sourced exclusively from certified Australian mines, among the most ethically regulated supply chains on earth.

    You know exactly where your ring came from.

  • Built to Be an Heirloom

    Solid gold does not degrade, tarnish, or expose base metal after five years.

    This ring is built to be worn for decades on decades before passing on.

    This is how gold rings were always supposed to be, solid, chunky and heavy.

  • Insured Express Shipping Worldwide

    Your ring ships fully insured, express - worldwide.

    Complimentary.

    A ring worth thousands deserves a delivery that matches it.
