Colour · Tone
GIA’s D–Z scale assesses the normal colour range, from colourless to light yellow or brown.
Clarity · Characteristics
Clarity evaluates internal and surface characteristics. Assessment under 10× magnification is important in grading.
Cut · Light performance
Cut concerns how proportions and craftsmanship affect light. It is distinct from shapes such as round, oval or pear.
Centre-stone weight and total carat weight differ.
Centre-stone carat weight refers only to the main stone. Total carat weight is the combined weight of the specified stones. Check which value a product description gives, and ask our team if anything is unclear.

Reports and stone details
Certificates and laboratory reports are specific to each product. A laboratory name, report number or stone detail shown for one piece does not automatically apply to another.
Before purchasing, ask for the stone’s report, whether it is natural or laboratory-grown, and any treatments. When a report number is supplied, verify it through the issuing laboratory’s official service.

Ring measurements
Ring size should be considered alongside the intended finger and the width of the band. Professional measurement is the best way to confirm your choice.
- Choose a ring that fits the same finger comfortably.
- Measure the internal diameter in millimetres, excluding the band itself.
- Share the measurement and the design you are considering with our team to match the product’s available sizes.
Images on this screen are not life-size measurement templates. Home measurements are approximate; temperature, finger shape and band width can affect fit.

Care and servicing
Protect your jewellery from impacts and store pieces separately. Diamond’s hardness does not make it unbreakable. Use a soft lint-free cloth; leave ultrasonic or steam cleaning to a professional assessment.
Different stones, treatments and settings can require different care. If you notice a loose stone or setting, consult our team before wearing the piece. Service scope and pricing are assessed after inspection.
Delivery and tracking
Delivery arrangements depend on the piece and destination. If you need your purchase for a specific date, contact our team before ordering. You can follow your order status in your account.
