Men choose most frequently for a solitaire ring to propose to their girlfriends. And to be honest: we can’t disagree.  This classic model is timeless, elegant and fits every type of women. But it’s the central diamond that attracts all the attention, mostly brilliant or princess cut. How big this one is, depends on your budget. We would like to emphasize that the size is not the most important aspect, but the quality is. In short, you better opt for an engagement ring with a smaller diamond and a higher quality. Of course, also the precious metal is important. The choice depends on different factors. That’s why we explain the 4 most important precious metals again.

Yellow gold

A solitaire ring looks very classically in yellow gold. This means, it is the perfect model for women with a timeless dressing room. On top of that, yellow golden diamond rings have a warm appearance. This precious metal stands out extra in combination with black clothes (think: the little black dress) But yellow gold is also nice combined with a white outfit during the summer time.

White gold: rhodium plating & maintenance

White gold gets its bright, silvery look because it is alloyed with white metals and typically finished with a thin rhodium layer. That rhodium gives the metal a luminous surface that makes the diamond pop, but it is not permanent: everyday wear gradually thins the plating and a slightly warmer tone appears beneath. Signs that a piece needs re-plating include a duller surface, faint yellowing near the edges or prongs, or small spots where the metal tone differs. Re-plating restores the original white shine, so expect occasional maintenance if you prefer a consistently bright finish. When shopping, ask how a piece is finished and how the workshop recommends checking the plating over time, so maintenance can be planned without surprises.

Platinum: heft, patina and hypoallergenic considerations

Platinum is naturally grey and does not require a rhodium finish. It is denser than gold, which gives a noticeable weight and a feeling of substance on the finger. Over time platinum develops a soft patina, a satin-like texture made of tiny shallow marks; many people value this lived-in character, although deeper scratches need professional attention. Because platinum is alloyed with little else, it is also a good option for those with sensitive skin, as it is less likely to cause reactions. The trade-offs are mainly visual and tactile: platinum keeps a true grey colour without re-finishing and offers strong durability, but it feels heavier and shows a distinct ageing pattern compared with a freshly rhodium-plated white gold ring. For buyers weighing appearance against upkeep, platinum offers a low-intervention route to a lasting white finish.

Red gold

Red gold is one of the most special precious materials. In comparison with for example yellow or white gold is this precious metal not exposed to fashion trends.

At this moment, red golden jewellery is very wanted, because of their warm appearance. Red gold is namely an alloy from (yellow) gold and copper. A red golden solitaire ring is at least to be called an original choice, and especially your upcoming fiancée will love it.

Metals to avoid for daily-worn engagement rings

Sterling silver is generally too soft for an engagement ring meant for daily wear; it scratches and deforms more easily than gold or platinum, so a silver solitaire will show wear quickly and may need frequent attention. Rose or red gold contains copper as a key alloying metal. That copper creates the warm hue but can cause sensitivity in some people and may subtly deepen the metal tone over time. If you or your partner have known metal sensitivities, mention this when choosing a rose gold setting and ask the jeweller about the alloy composition.

Which metal should you choose? Quick recommendations by budget and lifestyle.

• Best long-term durability and lowest maintenance: platinum. If you prioritise resilience and a consistently white finish, platinum keeps its colour naturally and develops a soft patina rather than relying on a plated surface. It feels heavier on the finger, so choose it when longevity and a premium feel matter most.
• Best white-metal look on a modest budget: 18K white gold with a rhodium finish. It gives the bright, diamond-enhancing white appearance associated with platinum, but the thin rhodium layer will wear over time and need re-plating to restore the initial tone.
• Warm, traditional appearance: 18K yellow gold. For a rich, classic colour that flatters warm skin tones and pairs well with darker clothing, 18K keeps a vivid hue while remaining suitable for daily wear.
• Romantic, modern rosy tone: 18K rose/red gold. Its copper content gives a distinctive warm tint that can deepen subtly with time; check for any copper sensitivity if skin reactions are a concern.
• If budget is the overriding constraint: lower-karat golds (for example 9K or 14K) are harder and less costly, but their colour is less vivid than 18K. Present these options factually rather than as preferred Baunat choices.

These pointers help match the metal to how the ring will be worn and cared for: choose platinum for minimal change over decades, white gold if you want the white look with occasional maintenance, and 18K yellow or rose gold if you prefer warm tones and classic character.
