Buying guide
Platinum is naturally white, so it never needs replating and keeps the setting looking bright around the center. It is dense and heavy for its size, and when it scratches the metal moves aside rather than wearing away, which helps prongs hold up over years of wear. Those qualities make it a steady choice for a 0.5 carat platinum engagement ring that will be worn every day.
Solitaire styles come with a plain band, a rounded plain band or a pave band of small lab-grown diamonds. The hidden halo adds a row of small stones beneath the center, seen from the side. A vintage-style halo surrounds the center and sits on a three-row pave band. Side-stone designs pair the center with marquise and round accents or pear and round accents, and the three stone ring sets a smaller stone on each side. The cathedral style lifts the center on arches over a graduated pave band.
Prices cover the finished platinum ring with its half carat lab-grown diamond center. They start under $1,200, and most fall between about $1,600 and $1,900. Accents add to the ring's overall stone weight, while the 0.5 carat figure is the center alone.
