Sixteen carats of architectural white light — the 16.5ct DEW White Moissanite Emerald Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. At 16.5ct DEW in the emerald cut, this ring creates a stone surface of approximately 21×15mm — a cinematic rectangle of white light that fills the hand with geometric authority at a scale that occupies its own category in wearable jewelry.
A 10ct DEW emerald cut measures approximately 16×12mm. A 16.5ct DEW emerald cut measures approximately 21×15mm — about 30% larger in both length and width. The visual difference is not subtle. At 16.5ct, the step facets become large enough to function as mirrors — reflecting specific light sources individually, creating defined, room-sized planes of white light. The 10ct is a large, commanding stone. The 16.5ct is an architectural object. The stone does not merely sparkle — it reads, reflects, and transforms. It is not for every buyer; it is for the buyer who has decided that scale is its own aesthetic category.
At 16.5ct DEW, this ring is beyond what most people would classify as an everyday stone — but "everyday" is a relative term. Collectors who own multiple large-stone rings wear rings of this scale regularly for photography, events, travel, and professional contexts where a significant jewelry presence is appropriate or desired. The emerald cut at this size has no sharp edges, catches minimally on fabric, and is in many ways more practical than a similarly-scaled round brilliant. It is a statement of deliberate intent, not circumstance. Whether that intent belongs in your daily wardrobe is a question only you can answer.

Your moissanite arrives with a GRA (Global Gemological Research Academy) report recording its carat weight, colour, clarity and cut grade.
Moissanite is one of the hardest gemstones and has more fire and brilliance than diamond (2.42 refractive index, 0.044 dispersion).
Moissanite was first identified in 1893 by Nobel laureate Henri Moissan, in meteorite fragments from Arizona's Canyon Diablo crater. Natural moissanite is so rare that the stones in fine jewellery today are created in a lab.

Watch it in motion
Large single stones are easiest to judge in motion. The video shows the face breaking up and reforming as the ring turns, which no single frame can stand in for.

Square to the camera the stone is a rectangle with its corners cropped. The faceting is brilliant rather than stepped, breaking the light into short flashes across the face.

The side shows how deep the stone is. It stands well above the band, held at the corners, and the base narrows to a line rather than to a single point.

From behind, the head is a plain open frame. Nothing fills the space under the stone, and at each shoulder the band forks into two arms, one to the top of the basket and one to the bottom, with an open triangle between them.

The band is narrow and round in section, and it does not change width as it reaches the stone. There is nothing set into the shoulders to compete with the centre.
Because the band stays thin, the head takes up the whole top of the finger. The stone is held at its corners and stands clear of the skin.
