4 Prong Solitaire Moissanite Ring, 0.5ct to 2ct s925

A four prong solitaire is the simplest ring setting there is, and that is its strength. Four prongs hold the stone in place while exposing most of its surface to the light, so nothing hides the facets. The setting is also easy to clean and easy to check for wear. Because the design is plain, it suits men and women equally well, and it works as an engagement ring, a wedding ring or a daily piece.

Two stone options are offered, and the trade-off is honest. Moissanite is harder at 9.25 on the Mohs scale, so it keeps its polish, and it has a refractive index of about 2.65 against a diamond's 2.42, so it flashes more. Zircon is softer, less fiery and cheaper, and it works as a gift or an occasional ring. The band is s925 sterling silver. The GRA certificate applies to the moissanite option only, so check you have chosen it if the certificate matters to you.

The sizes are listed by millimetre and carat. The 5mm 0.5ct is a modest everyday stone. The 6.5mm 1ct is the classic engagement proportion. The 8mm 2ct is a bold choice with real presence on the hand. Each size is available in moissanite and in zircon, and in white gold, yellow gold and rose gold finishes. Ring sizes start at 4 and run up in half sizes, including 8.5 and 9, so there is a fit for most fingers.
