Ring Buying Guide

SAAT Gemology Team·5 min read

Two ways to start

You can browse fully finished ring settings and pair one with a diamond, or start from a diamond you love and build a ring around it. Both paths end at the same place — a ring in the setting, metal, and stone you chose. The only difference is where you begin.

Choosing a setting style

Setting style is the most personal decision in the process, and it shapes everything else:

  • Solitaire — a single diamond, minimal metal. Timeless, and the style that puts the diamond front and centre.
  • Halo — a ring of smaller diamonds surrounding the centre stone. Makes the centre diamond look larger and adds sparkle.
  • Pavé — small diamonds set along the band, adding continuous sparkle without competing with the centre stone.
  • Three stone — a centre diamond flanked by two smaller stones.
  • Vintage — intricate metalwork and detailing inspired by earlier eras.
  • Bezel — the diamond is fully wrapped in a metal rim, the most protective setting and popular for active lifestyles.
  • Cathedral — the band arches up to the centre stone for a raised, elegant profile.

Browse settings before you commit to a diamond shape — some styles suit round and oval stones better than fancy shapes like emerald or marquise.

Choosing a metal

See our full Metal Guide for detail, but as a quick rule: platinum and white gold suit cooler skin tones and higher-colour diamonds, while yellow and rose gold suit warmer tones and can flatter a touch of warmth in lower-colour stones.

Matching the diamond to the setting

A few pairings worth keeping in mind:

  • Prong count and style should suit the diamond shape — round and princess cuts need different prong configurations than pear or marquise.
  • Higher-colour diamonds (D–F) show best in platinum or white gold, where nothing competes with their whiteness.
  • A halo setting can let you size down the centre diamond while keeping a similar visual size — a useful budget lever.

Getting the size right

Ring size is the one measurement that's hardest to change once a stone is set. See our Ring Sizing Guide for how to measure at home. For a surprise proposal, borrowing a ring they already wear and tracing the inside is the most reliable method — and we offer free resizing within 6 months if an adjustment is needed afterward.

Building your ring, step by step

Our ring builder walks you through three steps:

  1. Setting — choose your style, metal, and band details
  2. Diamond — browse live inventory, filtered to complement your chosen setting
  3. Review — confirm your combination and see the full price breakdown before checkout

You can start from either end — setting first or diamond first — the builder keeps everything in sync either way.

If you're working to a deadline

If you have a proposal date or event in mind, order with as much buffer as you can and reach out to us directly — we're glad to advise on realistic turnaround for your specific setting and metal combination before you order.
