This classic engagement ring plays with the deep colour of three lapis lazuli stones, set in rhodium-plated 925 silver. The cabochon cut rounds the surface of each stone and concentrates the light on it, revealing a rich, dark purplish-navy hue shot through with fine golden flecks. The three stones were matched so that their tone stays even from the first to the last - none stands out with a lighter patch or a grey cast. In old lapidary workshops lapis lazuli was associated with idealism, intuition and harmony, which makes it a stone readily chosen for an engagement ring.

Each of the three stones is natural lapis lazuli, hand-selected for colour and clarity - hence the ring's high quality at a price that remains reasonable. Good stones in this colour are becoming harder to find, and silver is rising in price along with other precious metals, so buying today makes financial sense. The ring is made of refined European silver 925, free of nickel and other harmful additives, which means the metal in contact with the skin of the hand does not irritate it. A rhodium layer protects the surface from tarnishing and loss of shine, so the silver keeps its bright, even lustre for a long time. The French maker's mark on the piece attests to the origin of this silver.

For a family celebration, the ring pairs well with an elegant dress in a muted colour and a thin gold chain at the neck - in the warm light of evening the navy hue of the stones takes on more depth. It also suits classic accessories such as pearl earrings or a leather clutch. A hand wearing this ring looks well when offering a glass or shaking hands during a toast. The three stones set in a row give the hand a clear, orderly rhythm, typical of classic engagement jewellery.
