Engagement guide · Start here

How to buy an engagement ring.

Begin with the person, not a rulebook. The right ring balances style, lifestyle, proportion, meaning and budget, and you do not need every answer before speaking to us.

01 · The person

Notice what they already choose.

Look at the jewellery they wear repeatedly. Is it minimal, sculptural, vintage-inspired, colourful or unconventional? Which metal and visual scale appear most often?

Lifestyle matters too. Someone active with their hands may prefer a lower, protective setting. Someone drawn to expressive jewellery may want asymmetry, colour or unusual proportions.

  • What do they wear repeatedly?
  • Would they prefer restraint or a strong point of view?
  • Should a wedding band sit flush?
  • How active are their hands in an ordinary week?
02 · Budget

There is no salary rule.

The idea that an engagement ring should cost a fixed number of months’ salary is marketing, not a requirement. Choose a budget that feels responsible for your life.

A useful range lets a designer balance centre stone, setting, metal and detail intentionally rather than hiding compromises.

03 · Collection or bespoke

Start with a setting or start with a story.

Choose a Lark & Berry engagement design when a house silhouette already feels right, then refine the diamond, metal and size.

Choose bespoke when the feeling, practical need, reference or original idea should determine the design from the beginning.

  • Collection: begin with an existing design
  • Bespoke: develop the composition with a designer
04 · Diamond shape

The outline changes the first impression.

Shape describes outline and faceting style; cut quality describes how successfully the design is executed.

  • Round: balanced and highly brilliant
  • Oval: softly elongated with graceful coverage
  • Emerald: architectural step facets
  • Pear: curved and directional
  • Marquise: long, pointed and expressive
  • Cushion: soft corners and romantic structure
  • Radiant: angular with lively sparkle
  • Asscher: geometric step-cut pattern
05 · Setting

How the diamond is held changes the life of the ring.

Consider setting height, snagging, ease of cleaning and how a future wedding band will sit. Beauty and wearability should be designed together.

  • Solitaire: one centre stone
  • Halo: smaller diamonds frame the centre
  • Trilogy: three principal stones
  • Bezel: a clean metal rim
  • Pavé: small diamonds along the band
  • Toi et Moi: two principal stones in one composition
06 · Metal

The setting has a colour too.

Yellow gold feels warm and distinctive. White gold has a bright finish that may require rhodium maintenance. Rose gold carries a pink tone through its alloy. Platinum is naturally white and develops its own patina.

Available metals depend on the individual design. Product details or a personal quotation should identify exact alloy and finish.

07 · Size & timing

Measure thoughtfully. Share the date early.

A jeweller’s measurement or a well-fitting ring worn on the correct finger gives the strongest size estimate. Avoid relying only on string or an unverified printed guide.

Made-to-order and bespoke rings require time for stone confirmation, design, production and finishing. If you have a fixed date, share it at the first conversation. Rush work from approximately two weeks may sometimes be possible but must be confirmed in writing.

  • Confirm whether displayed price is setting-only or complete
  • Review the individual grading report where supplied
  • Consider wedding-band fit
  • Confirm size, metal and production timing
  • Read warranty, care and returns terms

Start with the route that feels natural.
