Buying guide
Platinum is naturally white, so it keeps a colorless center looking bright without replating. It is dense and heavier than gold, and when scratched the metal shifts rather than wearing away, which helps prongs keep their grip over time. A 1.5 carat center in platinum feels solid on the hand and suits a ring worn every day.
A plain band is the purest solitaire look and sits flush with a wedding band. The rounded plain band has a softer, comfortable profile. A pave band adds small lab-grown diamonds along the top. The hidden halo places small stones beneath the center, seen from the side. The cathedral style lifts the center on arches above a graduated pave band. Accents add to the ring's overall stone weight; the 1.5 carat figure is the center stone.
Round gives the most sparkle, oval, pear and marquise look larger from above, and emerald and asscher step cuts show broad flashes. These platinum rings start under $1,900, and most fall between about $1,900 and $2,450, with the center included.
