Choose 18K when colour richness matters most — heirloom pieces, occasion wear, and yellow or rose gold designs where the higher gold content is visibly warmer. For hard daily wear, 14K's extra hardness has the edge; for everything meant to be admired, 18K is the classic answer. Read our full 14K vs 18K guide.

• 18K is hallmark-stamped 750 — 75% pure gold.
• Every diamond is IGI-certified and ships with its report.
• Slightly softer than 14K — store pieces separately to avoid scratches.
• Best suited to sensitive skin thanks to the higher gold purity.
