Retro in character and exceptional in its detail, this engagement ring builds its charm around a single, very big cabochon moonstone. Looking at it from different angles, you'll catch a blue flash that glides across the surface of the stone like a thin ribbon of light - this is adularescence, a phenomenon characteristic of this very stone. An open, elaborate vintage-style setting surrounds it with a delicate tracery of silver, giving the whole piece the character of a find from decades past. Moonstone has long been associated with intuition and inner awareness, and has also been a companion to moments of meditation. This symbolism makes it a fitting choice for an engagement.

For this piece we chose a stone with an exceptionally pure, deep glow - it was this quality that determined its character and final craftsmanship. Silver and fine natural stones are steadily rising in price, and specimens with this kind of colour are becoming harder to find, so this purchase makes sense from a price standpoint today. The ring is made of pure, refined sterling silver 925, giving it a European standard of craftsmanship felt in every detail of the setting. A layer of rhodium protects the surface against tarnishing and scratches, so the metal keeps its shine for a long time without extra care. The alloy contains no nickel or other irritating additives, so you can wear it without worrying about skin irritation. The metal is stamped with the French maker's mark, which attests to its origin.

At its larger size and weighing 8.2 g, the ring makes a clear statement on the hand, so it pairs well with an understated outfit for a meeting in the city. A camel-coloured trench coat, a cool grey turtleneck and simple jewellery in the background let the moonstone itself catch the eye with every gesture of the hand. It also works beautifully with a cup of coffee in hand, as the blue flash catches the light from the window. The retro form and natural stone make for a combination rarely found in modern engagement jewellery.
