Backes & Strauss, the world's oldest diamond company, has collaborated with Gemfields, a leading supplier of coloured gemstones to create the bespoke piece unique Piccadilly Princess Royal Emerald Green timepiece.

This is the third in a series of five unique watches, following the release of the Piccadilly Princess Royal Colours in 2014 and Piccadilly Princess Royal Blue in 2015.

The series commemorates the 225th anniversary of Backes & Strauss, whose creations are inspired by London’s Regency Era, when architect John Nash led initiatives commissioned by the Prince Regent to liven and recreate the city’s landscape.

Established in 1789, Backes & Strauss has constantly looked forward, pioneering new diamond cutting techniques and enthralling connoisseurs with its compelling designs, remarked Knadjian. Today, it is part of the Franck Muller group.

Architecture, art and culture flourished in this period, particularly the growth in the city's commitment to nature and the environment, said the statement from Backes & Strauss.

The vibrant green emeralds on this Piccadilly Princess timepiece reflect London's devotion to its natural landmarks and lush green parks, celebrated and cherished from the Regency Era to today, it added.

"A shared dedication to environmental and human rights responsibility along with commitment to high-quality cut and polished stones are what have encouraged us to continue a partnership and create another masterpiece with Gemfields," remarked Vartkess Knadjian, CEO, Backes & Strauss.

"This breath-taking, natural green vision displays 245 Zambian emeralds with 10 different cuts for a total of 31.91 carats. The responsibly sourced gems combined with Backes & Strauss' carefully engineered design create a brilliant piece found nowhere else in the world," he noted.

The exquisite quality of these vivid emeralds is attributed to the delicate and sustainable unearthing methods used in Gemfields' Kagem Mines in Zambia, he added.-TradeArabia News Service
