Discover Moi Moi’s best-selling engagement rings

The Harmony Collection brings together three of Moi Moi’s most-loved designs: Holly, Hattie and Harmony.

Hattie and Harmony are wonderful options for those wanting the look of a solitaire with a little extra sparkle. Both rings have a stone-encrusted under-rail and bridge, which has been mindfully designed to prevent friction when worn with a wedding band. While Hattie showcases a plain polished band, Harmony features a sparkling half stone-set band.

The ‘Holly’ ring is a classic solitaire engagement ring with a delicate prong setting that enhances the stone’s natural radiance, paired with a smooth half-rounded band for lasting comfort. This ring balances modern simplicity with timeless charm — perfect for daily wear and lifelong elegance.

Crafted in luxurious 18K gold and your choice of premium lab grown diamond or SUPERNOVA Moissanite, the Harmony Collection is a celebration of ethical and enduring elegance, brilliance and style.

Choose from up to seven popular engagement ring cuts, each offering unique beauty and brilliance.

Classic engagement rings in timeless shapes

Our Holly, Hattie and Harmony engagement rings come in five of the most highly sought-after cuts:

  • Round – a great choice if you’re seeking maximum, all-over sparkle
  • Oval – a timeless and elegant shape that helps elongate the finger
  • Cushion – this romantic option features soft edges for vintage-inspired charm
  • Pear – pear cuts create a flattering, elongated look that’s both unique and eye-catching
  • Emerald – sleek and sophisticated, emerald cuts highlight clarity and bold style, offering sharp flashes of light rather than all-over sparkle

In addition to these five, the Holly ring also comes in two additional cuts:

  • Marquise – a distinctive, elongated cut with pointed tips that creates a regal, elegant silhouette while maximising the appearance of size and sparkle
  • Square – modern and versatile, the square or princess cut is all about clean lines, perfectly balancing brilliance with contemporary style

Frequently Asked Questions

What makes the Harmony Collection engagement rings a classic choice?

The Harmony Collection includes three of our best-selling designs: Holly, Hattie and Harmony. These are classic engagement rings in the truest sense, with elegant prong-set solitaire centre stones and subtle accent stones for added detail. Dazzling without being overwhelming, these rings look simply beautiful on the finger and pair effortlessly with a wedding band.

What engagement ring cuts are available in the Harmony Collection?

Our Holly, Hattie and Harmony engagement rings both come in Round, Oval, Cushion, Pear and Emerald cuts. These are some of the most popular engagement ring shapes right now, however they are also time-honoured styles that will retain their elegance for years to come.

Can I choose between lab grown diamonds and SUPERNOVA Moissanite?

Yes, our Harmony Collection is available in your choice of lab grown diamond and SUPERNOVA Moissanite. We are also able to customise your design with a mined or coloured gemstone, if you’d prefer. We recommend booking a consultation with a dedicated Moi Moi custom design consultant to discuss your options. If you’re unable to visit in-person, we also offer virtual consultations for your convenience.

What’s the difference between the Holly, Hattie and Harmony engagement rings?

The main difference between Hattie and Harmony lies in the design of the band. Hattie features a plain, polished band, while Harmony showcases a half stone-set band.
