Nadia Neuman and Mondial by Nadia are thrilled to share that their piece, The Kaleidoscope, has been announced as the most distinguished prize winner, the Champion of Champions at the 7th International Jewellery Design Excellence Awards, held at the 2025 Hong Kong International Jewellery Show last week.

The Hong Kong International Jewellery Show is the landmark event hosted by the Hong Kong Trade Development Council – and is among the most important exhibitions and markets for fine jewellery in the world. The show is attended by over 80,000 jewellery professionals. The International Jewellery Awards are among the most prestigious in the world with national prize winning entries from over 80 countries competing for these awards – and the supreme award, the Champion of Champions. The competition has not been held since the pandemic, adding to the excitement and anticipation of this year’s contest.

The Kaleidoscope, designed by Nadia Neuman and crafted by Burt Muller is a strikingly beautiful, technical and innovative design in 18ct yellow and white gold with natural coloured and white diamonds. All of the coloured diamonds have bee sourced from Australia from the famous Argyle and Ellen Dale mines. The piece features a fully functioning coloured diamond kaleidoscope pendant. The necklace has been made with interchangeable components to allow versatility in how it may be worn, to suit the wearer’s desires. The magnificent piece of jewellery is made up of three parts, a necklace, a pendant and of course, the operable kaleidoscope.  

The incredible, one-of-a-kind design has a total diamonds weight of 32.26cts, including natural-coloured diamonds weight of 23.49cts. The coloured diamonds featured in the piece are natural champagne, yellow, cognac, orange, blue and pink diamonds, in various traditional and innovative  cuts. Unusually for finished jewellery, the design incorporates various shaped rough diamonds  including a matched pair of yellow octahedrons. Rough diamonds are incredibly unique, as they are formed naturally by the Earth over billions of years, no two stones being identical, which adds to the  design’s individuality. Nadia has an intense admiration for rough diamonds, and they heavily  influenced the ancient and yet futuristic aesthetic of the design. 

This highly technical  design creates unprecedented versatility, transforming when worn. The design was crafted around the technical challenges of  realising the optical design of a kaleidoscope which uses coloured diamonds to create the kaleidoscopic effect, this in turn inspired the rest of the bold creation. Despite the complex design, the piece is highly wearable.  

Nadia Neuman explains that she knew she was destined to create a piece with coloured diamonds.  Since she began her career, she has always had a deep fascination of how light affects and influences the colours in the diamonds, she quotes, “nothing has colour without light, it is remarkable how light  influences the colours in the diamonds to change and transform”. Her admiration of the relationship  between colour and light was the muse behind The Kaleidoscope. The inclusion of rough diamonds was also a natural gesture for Nadia: “I have been drawn to rough diamonds since my mother, Maria Neuman, created one of the first rough diamond collections in the world here in Sydney in 1989” she said.

“Kaleidoscopes are a very sentimental object to me, they evoke happy nostalgic feelings of my childhood. I loved the idea of creating a design that was a juxtaposition between a piece of fine jewellery and something more playful. I enjoy designing fine jewellery that is presented in a non-traditional, unique way”, says Nadia.  

Another extraordinary feature of Nadia’s design is that every natural-coloured diamond in the piece comes from Australia’s Argyle Diamond Mine. Argyle Diamonds have been revered due to their rarity, found only in the remote and hauntingly beautiful landscape of the East Kimberley region of Western Australia. The Argyle Mine has played an extraordinary role in the diamond world, the source of the finest pink and red coloured diamonds in the world, renowned for their richness, strength and purity of colour.  

Nadia Neuman and the Neuman family have been in the vanguard of offering and promoting Argyle diamonds to the jewellery industry for nearly forty years. The creation of The Kaleidoscope brings a lifetime of experience and creativity shared by the Neumans – with Nadia’s recognised international reputation as one of Australia’s finest jewellery designers.

The retail value of this unique expression of the jeweller’s art is AUD290,000. From today, it is on display in the Mondial by Nadia boutique, Strand Arcade, Sydney.
