This blue topaz solitaire ring pairs a slim, minimalist band with one striking stone set centrally on the hand. The faceted cut breaks light into small flashes, and the colour itself brings to mind the cool water of a mountain lake. The form is simple and low-set, so the stone never gets lost in the setting - it's the stone that draws the eye as the hand moves. Despite its very small size, the ring stays light on the finger and can be worn every day, not just on special occasions.

Every topaz for this solitaire was examined individually before it reached the jeweller's hands - what matters is the purity of colour and depth of blue, not the sheer size of the stone. The price of silver and of good coloured stones rises year on year, so buying now makes plain practical sense. The band is made of refined sterling silver 925 of European quality, and a thin layer of rhodium protects the surface from tarnishing and keeps the shine intact despite daily wear. The alloy contains no nickel, the metal responsible for most contact allergies, so the ring can be worn without worrying about irritation. The silver additionally carries the French maker's mark, which attests to its origin.

It looks best in a total black outfit - a black top or a simple turtleneck creates a backdrop against which the blue of the topaz immediately catches the eye. It also works well with a dark, long-sleeved sweater, when the hand stays the centre of attention. This is a ring for everyday wear, but it rounds off a subdued evening look just as well, without any extra jewellery on the wrist or neck.
