This Art Deco vintage brooch, circa 1920, not only captures the essence of the era but also kindles a sense of nostalgia and wonder. The masterful reverse intaglio crystal, a technique refined by Emile Marius Pradier, depicts two Jack Russell Terriers with mesmerising detail and depth, evoking memories of a bygone era. Framed in 18K yellow gold and platinum, and adorned with 44 rose cut diamonds and four sapphires, this piece reflects the geometric and abstract art influences of its time. It is a tangible connection to the past, offering a glimpse into the artistic marvels of the early 20th century, and a testament to the timeless bond between humans and their canine companions.

The deeper the carving, the more pronounced the three-dimensional trompe l'oeil effect, which is sometimes enhanced by a backing of thin layer of mother-of-pearl. Diamonds 44 rose cut diamonds . We do not have the weight of the diamonds which is normal in our trade when it comes to rose cuts. All diamonds we offer are screened by the I.J.G.C. for whether they are natural or synthetic, and all diamonds in this jewel are 100% guaranteed to be natural. Precious stones Four sapphires . We did not check if the sapphires are lab produced or not as this information has no influence on the value of this jewel. Natural sapphires and lab produced sapphires were both used in this era, rather more for their effect than for their intrinsic value.
