This engagement ring with rose quartz gives off a warm, rosy glow that shifts in intensity as your hand moves - brightening one moment, receding into the depths of the stone the next. The cabochon cut gives it a soft, domed surface, while two cubic zirconia stones set on either side add a fine, cool sparkle that contrasts with the warmth of the central stone. The vintage silhouette of the band, with delicately carved lines, recalls forms from decades past, and the very big size of the stone means the ring sits well on the hand.

Only a small share of the raw material examined makes it into this piece - what matters is depth of colour and the clarity of the quartz, free of cloudiness. Good stones of this class are increasingly rare today, and silver prices keep rising steadily, so buying at this price makes sense right now. The rhodium layer protects the silver surface from tarnishing and scratches, meaning the ring needs cleaning less often and keeps its shine for a long time. The 925 fineness confirms the purity of the alloy - refined European silver, free of nickel and harmful additives. The piece bears the French maker's mark, which guarantees the origin of the metal.

For office wear, it pairs well with a smooth shirt and a blazer in muted, earthy tones - the rose quartz softens the severity of such an outfit. In the evening, it works well with a simple dress in a cool shade of grey. Rose quartz is traditionally associated with love, tenderness and harmonious relationships. That association makes this ring a natural choice for an engagement.
