• ✓ Gold type and purity (e.g. K18, 10K, Platinum 900/850)

Available in Japanese and English versions. Pre-order available — please specify your language preference when placing your enquiry.

Diamond Quality

We offer two standard diamond categories to suit different price points and markets:

  Bright, near-colourless diamonds. Ideal for customers who prefer a classic, brilliant white appearance. SI clarity class.

  Warm-toned diamonds at a more accessible price point. A popular choice for everyday wear and value-conscious buyers. SI clarity class.

Both categories use SI clarity class diamonds as standard, offering excellent value with eye-clean options available.
