Buying an ultra-thin ring eternity band rings


We advise all clients to avoid ultra-thin eternity rings. Very thin ring eternity band rings lack the necessary strength and durability offered by minimum widths. We recommend no narrower than 1.5  to 2mm wide for a diamond eternity ring.

Thin Platinum eternity rings vs thin white gold eternity rings


Many clients favour think Platinum eternity rings owing to the additional strength of this popular precious metal. In addition, Platinum provides a natural white metal choice. Over time, Platinum wears to a natural patina, but does not change colour unlike white Gold which requires refinishing from time to time.
