The Definitive Guide to Choosing an Engagement Ring

Choosing an engagement ring is a process which brings together symbolic intention, technical criteria, dreams and aesthetic sensitivity.

The engagement ring is a jewel which carries emotion in itself, often embodying the expectations of both the giver and the recipient. The decision rests on a clear understanding of the materials, the quality of the gemstones and the style which best reflects the identity of the person who will wear it.

The ideal engagement ring is one which balances longevity, proportion and meaning, respecting tradition, individuality, the dream of the person who wears it and the relationship that inspired it.

What Defines an Engagement Ring?

Traditionally, the engagement ring is conceived as a central piece, often featuring a precious stone, usually a diamond, set in a way which highlights its presence and luminosity.

Three fundamental elements can be distinguished:

  • The central precious stone
  • The precious metal of the setting
  • The classic, contemporary or unique design

The harmony between these three factors determines the final quality of the piece.

How to Choose the Diamond?

The diamond remains the classic choice, not only for its high degree of hardness, but also for its unique ability to reflect light (to sparkle) from which the name “brilliant” derives.

The quality criteria are based on four essential characteristics:

  • Carat: determines the size of the stone
  • Cut: determines the diamond’s ability to sparkle, through the way light is reflected
  • Colour: the more colourless, the greater the value. An exception applies to diamonds of intense colour.
  • Clarity: measures the presence of inclusions


An excellent cut is decisive, as it directly influences the diamond’s sparkle.

Which Stone or Gemstone Should You Choose?

The gemstone traditionally used in engagement rings was the pearl, as a symbol of purity and because of its association with bridal jewellery.

Couples would choose whichever gemstone suited them best, in the colour they preferred. One need only recall Princess Diana’s famous ring, with its central stone: a 12-carat Ceylon sapphire in royal blue.

The use of diamonds in jewellery evolved considerably, owing much to advances in technology which enabled precise cutting, revealing their characteristic sparkle caused by the refraction of light. In antiquity and the Middle Ages, due to their extreme hardness, diamonds were used either in their rough state or with only basic cutting.

In Europe, the marketing slogan “A Diamond is Forever“ brought significant growth to the diamond market.

In Portuguese Jewellery (16th–18th centuries), Rui Galopim de Carvalho highlights the evolution of cuts in Portugal, focusing on the use of large rose-cut diamonds in civil jewellery from the second half of the 17th century and, later, on the impact of the discovery of diamonds in Brazil in the 18th century.

Today, although the diamond is the standard, pearls are making a return as a choice for brides seeking a classic, vintage style, even though they are gemstones that require extra care.

What Is the Best Metal for an Engagement Ring?

The choice of metal should take into account resistance, aesthetics and everyday wear throughout a lifetime.

Gold

Gold remains the most classic option. In Portugal, 19.2-carat gold is distinguished by its resistance and durability, while also allowing for technical craftsmanship.

  • Yellow gold: timeless, warm and traditional.
  • White gold: discreet and contemporary. Gold is naturally yellow, so it may lose its white tone over time, requiring periodic maintenance of the piece.
  • Rose gold: soft, with a distinctive character.

Platinum

Rarer and denser, platinum offers high resistance to wear and a naturally white tone.

  • Ideal for intensive wear
  • High durability
  • A sober and stable appearance over time


It is the most characteristic material for an engagement ring.

Choosing the Right Style

The design of the ring reflects the personality of the person who will wear it and the thoughtfulness of the person offering it, avoiding fleeting trends.

Consider asking close friends or the person’s mother or father for help. Take note of rings from the collection of the person who will wear it, so that advisers, jewellers or designers can interpret the style of jewellery they like.

When making the purchase, bring a ring the person wears frequently so that the correct measurements can be taken.

Common Mistakes to Avoid

  • Prioritising only the size of the diamond at the expense of the jewel as a whole
  • Choosing a style which is not aligned with the personal taste of both the giver and the recipient
  • Failing to consider daily wear
