Seventeen carats of geometric infinity — the 17.0ct DEW White Moissanite Asscher Solitaire Ring in 18K Gold Vermeil on 925 Sterling Silver, GRA certified. The Asscher cut at 17ct DEW is the largest Asscher in GEMHUB's collection — a stone of approximately 21mm square, the hall-of-mirrors effect operating at a scale where it ceases to be a visual property and becomes an experience.
A 17.0ct DEW Asscher cut measures approximately 21mm square. For reference: a US quarter coin is 24mm in diameter. Set in a ring, a 21mm square stone extends significantly beyond any finger. The step facets, at this size, are no longer individually small — each one is a mirror-like surface approximately 7–10mm wide, reflecting distinct planes of white light. Looking into the table of this stone at 17ct is not like examining a gemstone. It is like looking into a floor, then a wall, then a ceiling, all simultaneously reflected in a geometric pattern that has no clear beginning or end. It is the hall-of-mirrors at human scale.
The largest known natural diamond Asscher cuts in the world include the Cullinan III (94ct), Cullinan IV (63ct), and a small number of private-collection stones in the 20–40ct range. All of these are historical artifacts in institutional collections, not commercial products. Outside of moissanite, a 17ct Asscher cut stone is simply not commercially available at any price. This ring exists in a category with no natural parallel in the commercial jewelry market.

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
An Asscher throws light in long bars instead of scattering it into small points. The video shows those bars opening and closing, which is the part a photograph cannot hold.

Straight on, the outline is square with its four corners cut off. The facets are flat steps parallel to the edges, stacked in towards a small table at the top.

From the side the band is flat on the outside and tapers as it leaves the head. The head itself is a plain frame with no shaped gallery underneath it.

Behind the stone the frame is cut away, so the base is visible from underneath and light reaches it from both sides of the finger rather than one.

Against out-of-focus warm lights the stone stays white. The steps pick those lights up as separate bars instead of scattering them into small points.

The head sits square across the finger and covers most of the width between the knuckles. From the front the band is narrow enough to vanish behind the stone.
The outside of the band is flat, which stops the ring rolling as it is worn. The stone stands well clear of the skin rather than sitting down against it.
