• Free, fully insured shipping
• Made to order in Toronto

The biggest engagement ring story of 2026 is lab-grown going fully mainstream — and with it, larger, higher-quality stones for the same budget. Around that, a clear set of design trends has emerged. Here is what is defining the year, and how to tell a trend worth following from a classic worth keeping.

Key takeaways

• Lab-grown is now the default for a growing share of couples — enabling bigger, better stones.
• Elongated shapes (oval, elongated cushion, pear, marquise) lead.
• Hidden halos and toi et moi are the standout settings.
• Mixed metals, east-west settings and subtle coloured accents are rising.
• The smartest ‘trend’ is choosing a stone and shape she will love forever.

1. Lab-grown, mainstream

What was niche a few years ago is now a default consideration. Because a lab-grown diamond is identical to mined at a fraction of the price (see lab-grown vs mined), couples are choosing larger carats and higher grades without overspending — the engine behind almost every other trend on this list.

2. Bigger, better centre stones

With lab-grown economics, three carats and up has gone from rare to attainable — at top colour and clarity. Presence on the hand, once a luxury, is now a sensible choice. It is the thinking behind Montare's three-carat floor.

3. Elongated shapes

Ovals remain the runaway favourite, joined by elongated cushions, pears and marquises — shapes that look larger per carat and flatter the finger. Browse them in our shape guide or the oval deep-dive.

4. Hidden halos and toi et moi

The hidden halo — clean from above, sparkling in profile — is the setting of the moment, while the two-stone toi et moi continues to ride a wave of celebrity attention. Three-stone designs are quietly back, too.

5. Mixed metals, east-west and colour

Mixing metals (a white-gold head on a yellow band) is increasingly popular; east-west settings turn an elongated stone on its side for a modern look; and subtle coloured accent stones add personality without overwhelming the centre.

Trend vs timeless

Trends are a wonderful starting point, but an engagement ring is forever. The move is to anchor on what she genuinely loves — and on a stone cut to last visually as well as physically (see why Triple Excellent matters). A classic shape in a current setting is often the perfect balance.
