When choosing gold jewellery, you’ll often see terms like gold fill, gold vermeil, and solid gold. These aren’t just marketing words — they describe very different ways gold is used in jewellery making, which affects durability, longevity, and price.

I work with all three, because each one has its place. When they’re made properly, every one of them can create beautiful, long-wearing jewellery — it simply comes down to how you want to wear it and invest in it.

Let’s break them down.

✨ Gold Fill

Gold fill is one of my favourite materials to work with because it offers the look and longevity of gold, while remaining more accessible from a price point.

Gold fill is created by pressure bonding a thick layer of solid gold to a base metal core (usually jeweller’s brass). Unlike standard plating, this gold layer is mechanically bonded, not just coated onto the surface.

I use 12k and 14k gold fill, which gives that warm, true gold tone while still being durable enough for everyday wear.

Why it’s special:

Much thicker gold layer than standard gold plating
Highly resistant to tarnishing and wear
Safe for most sensitive skin
Can last many years with good care

Gold fill is perfect if you want jewellery you can wear regularly without the investment level of solid gold.

✨ Gold Vermeil

Gold vermeil is a beautiful option when you want the richness of high-carat gold colour, especially for statement pieces, pendants, and earrings.

To be classed as true vermeil, jewellery must be:

Sterling silver base
Plated with real gold
Meet minimum thickness standards

I plate my vermeil pieces in-house, which means I control the quality at every stage.

I use 18k gold vermeil, and I plate significantly thicker than standard industry levels:

Pendants & Earrings: 3 microns
Rings: 5 microns

Industry minimum is often around 1 micron, so this is well above standard.

Why thicker plating matters:

Dramatically increases longevity
Slows wear on high-contact areas (especially rings)
Maintains colour and finish longer
Gives a more luxurious, solid feel

Because I plate in-house, I can ensure consistency, quality control, and the finish I want for each design.

✨ Solid Gold

Solid gold is the ultimate heirloom material. It will not wear away, and with care can last generations.

Because of the value (and steadily increasing value) of gold, I create solid gold pieces made to order. This ensures you are investing in something made specifically for you.

I typically work in:

9ct Gold — durable, slightly softer gold tone, excellent for everyday wear
18ct Gold — richer colour, higher gold content, more luxurious feel

Why choose solid gold:

Lifetime material
Can be repaired, resized, remodelled
Holds intrinsic value
Ideal for heirloom and milestone pieces

So — Which One Should You Choose?

Honestly? There is no “better” — only what is right for you.

Gold Fill→ Everyday wear→ Long wearing→ Accessible luxury

Gold Vermeil→ High gold colour (18k tone)→ Statement pieces→ Silver base with luxury finish

Solid Gold→ Heirloom investment→ Lifetime wear→ Made-to-order craftsmanship

Why I Use All Three

I truly love working across these materials.

When gold fill and vermeil are done properly — with quality base metals, proper thickness, and good finishing — they can be incredibly long wearing and beautiful to wear daily.

Solid gold is something special. It marks moments, milestones, and legacy pieces.

Offering all three allows me to create jewellery that is:
