What carat size is best for a heart shaped diamond?

We recommend a minimum of 0.70ct for a heart shaped diamond so the distinctive heart silhouette is clearly visible. At 1ct and above, the shape becomes particularly striking and recognisable.

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.
