4x8mm Marquise Moissanite Necklace, D VVS1 in 925

A marquise pendant hangs point to point, so the stone lies along the chest in a slim, tapered line. That shape draws the eye downward and makes a neckline look longer, which is why it suits a V neck, an open collar or a shirt with the top button undone. At 4x8mm the stone is twice as long as it is wide. It is a delicate size, wearable all day, and it hangs straight without twisting on the chain.

The stone is D colour, VVS1 clarity moissanite. D is the top of the colourless range, so it reads white against a silver or gold setting, and VVS1 keeps the narrow tips clean. The tips matter most on a marquise, because they are thin and brightly lit and would show an inclusion first. Moissanite measures 9.25 on the Mohs scale, so the points resist chipping better than softer stones would, and its refractive index is about 2.65.

The setting is 925 sterling silver plated in 18k, offered in three finishes. Silver is the cool, neutral choice and reads closest to platinum. Gold warms the stone and suits the pendant against tanned or deeper skin. Rose gold is the softest and suits pale or warm skin. All three keep the look the same, so the choice comes down to what you already wear. Wear it alone, or layered under a longer chain.
