3mm Moissanite Bubble Pendant Necklace in S925 Silver

The bubble style is a rounded, compact pendant built around one 3mm moissanite. Small is the point. It rests at the base of the throat without swinging, it does not catch on knitwear, and it is light enough that you forget it is there. That is why a pendant this size ends up as the piece people wear every day, and the one they are slowest to take off at night. It also layers easily with longer chains without crowding them.

Moissanite suits a small pendant better than most stones. Its refractive index of about 2.65 is higher than diamond's 2.42, so even at 3mm it gives off visible coloured flash rather than a flat white glint. At 9.25 on the Mohs scale it is also hard enough to survive daily contact with collars, hair and bag straps without going cloudy, which is the usual way softer stones show their age on a pendant that never comes off.

The only choice is finish. Silver colour is cool, reads closest to platinum and matches white metal watches and rings. Gold colour is warmer and suits the classic pendant look. Rose gold sits between the two and tends to flatter most skin tones. All three are 18k plated over pure S925 sterling silver, so the plating sits on a base that will not tarnish the way plated brass does. Plating wears slowly with use, so keep the pendant away from perfume.
