1 Italy
What is special about Italian jewellery: Italy has a tradition of craft and artistry for fine jewellery that dates back to the 18th century. Ms Angela Loh, Singapore JewelFest festival director, said this is what sets their jewellery apart.
"Over the years, their craft has evolved into contemporary styles that are modern yet maintain the European country's rich heritage," said Ms Loh.
What you need to know: There are eight labels from Italy taking part in JewelFest.
Annamaria Cammilli, Orital, Rota e Rota, Zydo and Oro Trend are all well-known labels which have presented their works at the festival before.
Three labels - Leonori Gioielli, Massimo Raiteri and Giovannetti Gioielli - are taking part for the first time.
Leonori Gioielli, founded in 1962, is known for its intricate designs and attention to detail.
Massimo Raiteri's designs are inspired by emotion, poetry and art. Each collection reinterprets geometric shapes, lines and colours.
The brand also takes a strong stand against blood diamonds: It ensures that every piece comes from areas free from any conflict, does not involve illegal trafficking and workers extracting their diamonds are offered fair work environments.
Giovannetti Gioielli specialises in producing feminine and fashionable pieces, with an emphasis on colours.
2 Germany
What is special about German jewellery: German jewellers are known for harnessing the latest technology to create their jewellery designs.
"Conceptual design, impeccable precision and engineering are the hallmark of German fine jewellery that is iconic in its subtle elegance," said Ms Angela Loh, Singapore JewelFest festival director.
For example, jeweller Heinz Mayer has a patent for its Rolling Diamond technology, an innovation which sets diamonds in moving parts on hand-made jewellery.
What you need to know: Seven jewellers from Germany have been brought in for this year's JewelFest.
Buddha Diamonds, Hans D. Krieger Fine Jewellery, Heinz Mayer, Niessing and Stenzhorn are returning labels while Erich Zimmermann and Esvara Viva are first-timers to the festival.
Buddha Diamonds, as its name suggests, has patented Buddha-cut diamonds, which are sculpted and cut in-house from a single rough diamond.
The patented cut takes the classic form of the spiritual sage, sitting cross-legged with his palms placed together. It takes 10 times longer to cut as compared to a regular diamond.
Erich Zimmermann is another brand to look out for as an example of designs made using German engineering. Its Cocoon collection, an award-winning series, is known for its voluminous yet lightweight pieces, such as a rose gold necklace that features a string of leaf-shaped segments.
3 Middle East
What is special about Middle Eastern jewellery: Jewellers there draw from a rich history of techniques and cultures from various parts of the region. Influences range from ancient sculptures to oriental symbolism.
"The mystique and classic opulence of the Middle East is the alluring element in the design and craftsmanship of the jewellery brands from this region," said Ms Angela Loh, Singapore JewelFest festival director.
