Rectangular cut precision at statement scale — the 5.7ct DEW White Moissanite Radiant Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. The radiant cut at 5.7ct DEW combines a flattering elongated outline with the full light performance of a brilliant-cut stone.
Both are elongated shapes at approximately the same size, but they read differently. The radiant cut has sharp, defined corners and straight edges that create a bold, architectural look — more structured, more graphic. The oval has gentle curves that produce a softer, more organic silhouette — more romantic, more traditionally feminine. At equivalent carat weight, the oval often appears slightly larger due to its greater table surface area. Both choices are beautiful at this size; the decision comes down to whether you want sharp geometry or flowing curves.
No — properly manufactured moissanite does not cloud, haze, or change in clarity over time. This is a common question because some older or lower-quality moissanite from early production runs (pre-2000) occasionally showed surface haziness. Modern GRA-certified moissanite from reputable manufacturers is produced to a standard that prevents this issue entirely. The stone's crystalline structure is permanent and stable — it will look identical in 50 years as it does today, with regular cleaning to remove surface oils and buildup.
