Eternity versus half-eternity
A full eternity band has diamonds running the entire circumference of the ring. A half-eternity band has diamonds across the top portion only. Full eternity bands cannot be resized because any cut would remove a stone. Half-eternity bands allow resizing by up to one size in either direction. If the buyer's ring size is likely to change, half-eternity is the practical choice.
Channel versus pave setting
Channel settings protect diamonds between two rails of metal. They are secure, low-snag, and easy to clean. Pave settings use tiny beads or prongs around each stone. They create a dense sparkle surface but carry more maintenance. Micro-pave prongs can catch on fabric and loosen over time, particularly with daily active wear.
Matching the engagement ring
A wedding band is worn against the engagement ring, so the metal type, colour, and profile should be considered together. A curved or contoured band sits flush against a solitaire without a gap. A flat band can create visible space at the sides of certain engagement ring settings.

Direct answers
Common questions
Can a full eternity diamond band be resized?
No. Adding or removing metal across a full circuit of diamonds is not feasible. A half-eternity or specific open-shank design is the alternative if resizing is a concern.
What metal should I choose for a diamond wedding band?
Platinum is durable and does not require replating. 18ct white gold is lighter and more common in South African retail. Yellow and rose gold are suited to warmer diamond colours and contrast-focused styles.
How do I match a diamond wedding band to my engagement ring?
Match the metal colour first. Then check the profile height so the two rings sit flush. A jeweller can advise on contoured bands or custom-shaped shanks that fit specific engagement ring settings.
What diamond grade should a wedding band have?
Colour consistency across the band is more important than individual grade. G-H colour in matched stones gives a white appearance at moderate cost. Clarity in small stones is less critical, but I1 and below can show visible imperfections in larger pave stones.
Is a diamond wedding band a good investment?
Wedding bands are primarily personal items, not investment vehicles. Natural diamond wedding bands with good documentation hold value better than mass-market pieces, but they are not purchased primarily for resale.
