This lapis lazuli ring draws the eye with the deep navy of its stone, where fine flecks of golden pyrite scatter across the surface like specks of light. The cabochon cut shows off this rich, dark purplish-navy colour without any facets to break up the light - the stone stays smooth, full and self-contained. The shape is modern and distinctly large, sitting well on the hand, and the substantial 5.5-gram build makes the ring feel like more than just an accessory. In ancient cultures lapis lazuli was linked to idealism, intuition and inner harmony - an association that suits a wedding and engagement ring well.

We look at every stone for this model individually and choose the one where the navy is deepest and the pyrite forms the most striking pattern. Silver and good coloured stones get more expensive every year, so buying a ring like this now makes sense from a price standpoint. It is set in refined European silver 925, coated with a layer of rhodium - this metal protects the surface from tarnishing and scratches, so the ring needs less everyday cleaning. A pure alloy, free of nickel and other allergenic additives, can be worn without worrying about skin irritation. The piece carries the French maker's mark, which guarantees the origin of the metal.

For everyday wear it looks good with a chunky oversized sweater and a scarf draped over it in a calm shade of beige or grey - the navy of the lapis lazuli stands out against such an understated look. For a visit to the notary or a quiet dinner, it pairs well with a simple wool dress in a cool tone. As a wedding and engagement ring it stands out with a shape that doesn't copy the classic diamond solitaire, while still keeping the gravity fitting for such an occasion.
