Why are round diamond engagement rings more expensive than other shapes?

Round diamonds command a premium because approximately 50% of the rough stone is lost during cutting to achieve optimal light performance. This higher material waste, combined with overwhelming demand, makes round brilliants the most expensive shape per carat.

What is the ideal carat size for a round diamond engagement ring?

The most popular carat weight for round diamond engagement rings is 1.0ct, which measures approximately 6.5mm in diameter. For maximum value, consider 0.90–0.99ct stones — they appear virtually identical to 1ct but can cost 10–15% less.

Is rose gold suitable for everyday wear?

Yes. Rose gold is one of the most durable gold alloys because copper strengthens the metal. It is well suited to everyday wear and its colour will not fade over time.

Should I choose lab-grown or natural diamond for under £3,000?

Under £3,000, you can choose a larger lab-grown diamond (1ct–1.5ct) or a smaller but geologically rare natural diamond (0.5ct–0.7ct). Lab-grown maximises size and sparkle; natural offers rarity and tradition. Both are excellent choices.
