Flat top blue tourmaline and diamond ring


I Love this stone. I find it so intriguing. The shape, the colour, the unusual way it is cut.

Twice a year, we are visited by a German gentleman who resides in a gem cutting village. We look forward to these visits as he always has the most original, extremely large, unusually cut gems. I have never seen a gem cut in this manner before. Totally flat on the top with bold facets radiating from the centre under the stone. This creates mesmerising flashes of lagoon coloured blue when moved.


Tourmaline is a beautiful stone, it comes in many colours and hues. A tourmaline’s colour may be classified into green, blue, pink or yellow, but within each of these groups a variation in hue and saturation of colour is immense. Just for green, they can be described as ‘mint green’, ‘olive’, ‘olive with a brown tint’, ‘deep green’, ‘deep green with a blue tint’, ‘bi-colour, where one end is a different colour to the other end’ and the list of colour can go on. Rubelite is another name associated with tourmaline and it refers to the intense pink almost red tourmaline, these are highly prized compared to the paler pinks. Tourmaline has a Moh’s hardness of 7-7.5, and they can come in quite large stones which make them beautifully ideal for stunning cocktail rings and earrings.

What to do with such a gem! After many concepts and sketches (see below), Ewen the designer and craftsman here at Stephen Dibb Jewellery came upon the idea of enclosing the tourmaline in a two row of bevelled diamonds. We set the centre gem from below with an ingenious claw setting so we could keep the diamonds as close as possible to the blue of the tourmaline. Ewen then designed the striking T shaped band to further accentuate the oval centre piece.

Tourmaline-sketchThe ring was crafted totally in crisp white 18ct gold, we find blue gems and diamonds tend to look better in the white where emeralds and rubies look their best set in yellow gold. Notice the concave diamond set motif on the side of the setting and how the way the diamonds in the band end in the same shape.

This ring is truly a one of a kind because we can’t ever match the colour and the cut of the tourmaline. Recently I have fallen back in love with watercolour painting and was inspired to render this ring. The way the light played on the tourmaline was a joy and a challenge to paint. I am proud to have this level of design and craftsmanship produced in our studios.

This stunning piece can be viewed at Stephen Dibb Jewellery in Cleveland or we can arrange for a special viewing at Holland Park. To learn more about the Tourmaline stone and this stunning ring please don’t hesitate to contact us.
