A lapis lazuli cabochon takes center stage in this small ring with a distinctly retro silhouette. The stone's deep, saturated navy colour shifts in intensity with every turn of the hand - darkening almost to black in shadow, revealing a cooler, bluish tone in the light. Six small cubic zirconias encircle it in a delicate row, adding sparkle without stealing the spotlight from the main stone. Set in silver, this composition recalls jewellery designs from decades past and suits both everyday wear and more formal occasions.

Lapis lazuli with such an even, deep colour and clean texture is not easy to come by - a second piece with a similar character is easy to miss. Silver and quality coloured stones are rising in price, so a ring like this at today's price makes practical sense. The rhodium coating on the silver protects it from tarnishing and losing its shine, while the refined European 925 silver, free of nickel and other sensitising additives, keeps even sensitive skin comfortable. The French maker's mark struck on the piece attests to the origin of the metal. In old tradition, lapis lazuli was linked to intuition, harmony and ideals - which is why it is often chosen for engagement and promise rings.

In summer it pairs beautifully with a linen dress in a light ecru or sand shade - the navy of the stone contrasts strongly with the pale fabric and draws the eye with every movement of the hand. It also works well with a cotton shirt tied at the waist and simple gold bracelets worn on the same arm. It's worth pairing it with a thin band ring - the vintage form of the cabochon sits well alongside simpler, smooth rings.
