A lapis lazuli cabochon opens up this ring with a deep, saturated navy hue, threaded through with fine golden flecks. As the hand moves, those flecks seem to vanish and then catch light again, as if the stone shifted the density of its colour with every turn. Around it spreads a halo of twelve cubic zirconia stones that catch the light and trace the outline of the central stone. The form is modern, geometric, very small on the finger - the halo doesn't overwhelm, it simply frames the view of the lapis lazuli. This deep blue has long been associated with ideals and intuition, and in some jewellery traditions it was also treated as a symbol of harmony.

This particular combination of colour and clarity rarely comes together in a single stone, so a second piece with a similar character won't be easy to find. Silver prices are rising, and good stones of this class are getting more expensive right along with them, which makes buying at this price worthwhile today. The setting is refined European silver coated with a layer of rhodium, which protects the surface from tarnishing and keeps the shine lasting for a long time. The French maker's mark - a guarantee of the quality and origin of the precious metal - confirms that this ring was made to European standards of craftsmanship. At 1.5 grams, the piece stays light on the hand, despite the stone's bold character.

As a halo and engagement ring, it suits moments meant to be remembered, but it pairs just as well with a silk blouse or a little black dress for an evening out. Against a simple, dark outfit, the navy of the lapis lazuli draws the eye without needing extra jewellery on the wrist or neck. One turn of the hand is enough to set the blue of the stone and the sparkle of the cubic zirconia playing off each other.
