Retro in form and rich in blue, this engagement ring with three topazes brings the character of past decades to the hand. The stones, set in a single line, are matched in colour and clarity, so light passes through them evenly, and with every movement of the hand the facets catch the light differently, revealing new glimmers deep within the stone. This is a multi-stone ring that also works well as an engagement proposal for those looking for colour instead of a classic diamond.

We select the blue topaz for this piece for its uniform, deep colour, so that all three stones form a coherent, distinct line of blue. Silver and precious metals are rising in price, and good stones are becoming harder to find, so buying this ring now is a sound decision price-wise. The stones are set in refined 925 silver of European quality, bearing the French maker's mark - a legally protected mark registered with the French assay office, which attests to the origin of the metal. The rhodium layer is hard and scratch-resistant, so the surface does not tarnish and the shine lasts a long time. The alloy contains no nickel, the metal most commonly responsible for skin reactions, so the ring can be worn without worry.

The small size means the ring sits close to the finger and doesn't feel heavy on the hand, which makes it well suited to family celebrations. Paired with an elegant dress in a dark shade, it adds a touch of colour without overdoing it, and in the warm light of evening the blue of the topaz stands out clearly against classic silver accessories. The retro character of the setting pairs well with delicate jewellery with simple lines, so the whole look stays harmonious, and the three topazes draw the eye with every movement of the hand.
