Ring story · Bold & modern

Black diamonds,
in a striking zig-zag.

The Zig Zag Black Diamond Ring by Sethi Couture sets 28 rose-cut black diamonds in a bold zig-zag pattern, in rich 18k yellow gold. Moody, sophisticated, and unapologetically modern — bold edge and refined craftsmanship in one band.

Who she is

For the woman with
an edge all her own.

This is the one I pull for someone who finds white diamonds a little expected. Black diamonds bring a completely different energy — moody, confident, and modern — and she’s exactly the kind of person who can carry that off.

She loves the contrast of dark stones against warm gold, and she wants a ring with real personality and edge, not just sparkle.

Bold edge meets refined craftsmanship — a ring that stands out, and keeps standing out.
What sets it apart

Three things that make it
stand out.

01

28 rose-cut black diamonds

Twenty-eight rose-cut black diamonds (0.50 ct total) run across the band in a striking zig-zag. The rose cut gives a soft, subtle shimmer with depth and texture rather than high-gloss sparkle.
Why black diamonds
Black diamonds bring moody, modern energy a white stone never could — sophisticated, confident, and unmistakably different.
02

Dramatic gold contrast

Against rich 18k yellow gold, the black diamonds create a bold, elegant contrast — moody and sophisticated, unapologetically modern. It’s the kind of ring people notice.
03

A meaningful zig-zag design

The zig-zag pattern gives the band real movement and edge, balancing that bold energy with genuinely refined Sethi Couture craftsmanship. Distinctive, but beautifully made.
The maker

About Sethi Couture.

Sethi Couture is known for modern, finely crafted fine jewellery that balances edge with elegance — often with unexpected diamonds and clean, contemporary design. The Zig Zag band is a signature example: bold and moody on the surface, meticulously made underneath.

In real life

Bold, and genuinely
everyday.

The rose-cut black diamonds sit relatively low and secure in the zig-zag, keeping the ring practical for daily wear, and diamonds — black or white — are the hardest material there is, so it’s tough. It stacks beautifully with plain or white-diamond bands for contrast, and an occasional clean keeps the gold bright. A bold everyday ring with real staying power.

Common questions

FAQ — what people
actually ask me.

Are black diamonds real diamonds?

Yes — black diamonds are genuine diamonds with a dark, opaque colour. They offer a moody, modern alternative to white stones and are just as hard and durable.

What is a rose cut?

A rose cut has a flat base and a domed, faceted top, giving a soft, subtle shimmer with depth and texture rather than sharp, high-gloss sparkle — which suits black diamonds beautifully.

Can this be an engagement ring?

Absolutely — a black-diamond band like this makes a bold, modern engagement ring for someone who wants edge and individuality, and it doubles as a striking stacking piece.

Is it good for everyday wear?

Yes — the low-set diamonds and durable construction make it practical for daily life, needing only an occasional clean to keep the gold gleaming.
