Vicenzaoro January 2024 exceeds all the most optimistic prior expectations of the Vicenza – Italy gold and jewellery exhibition’s 70-year anniversary. Italian Exhibition Group’s «boutique show» closed today with a 3% increase in attendance at the Vicenza Expo Centre, surpassing last January’s record edition. Moreover, at this edition, six out of ten visitors came from abroad: the global jewellery industry has chosen, Vicenza will be a market hub for the next 70 years. IEG responds with the start of work on the new 22,000-square-meter hall.
THE VICENZAORO JANUARY 2024 NUMBERS
Foreign attendance has been confirmed at 60% of the total, arriving from 141 countries around the world, up from 136 in 2023: with Europe counting 53%, the Middle East 9.3%, Asia 10.5%, Turkey 8%, North America 7.2%, Latin America 5.1% and Africa 4.9%.
Among the most represented individual countries overall: the United States and Turkey; from Europe Spain, Germany, France, Greece and the UK; from the Middle East the United Arab Emirates, while standing out from Asia are India, China, Japan, Thailand and Hong Kong. The largest increases are for China (+188%), Japan (+44%), Colombia (+38%), Brazil (+36%) and France (+25%). Among the new entries at Vicenzaoro: Tanzania, El Salvador and Honduras. Veneto, Lombardy, Tuscany and Piedmont confirm an extremely positive trend for Italian attendance, which saw an overall increase of 3.2% compared to 2023.
T.GOLD ON THE RISE
At this edition, T.Gold, the leading international innovation showcase featuring the most advanced machinery for goldsmithing and the latest processes applied to gold and jewellery, organized in partnership with A.F.E.M.O., saw a 4.7% increase in attendance.
TIMEPIECES.
In the timepiece segment, VO Vintage consolidated its success with exhibitors up 22% for vintage watches and jewellery open to the B2C public, with collectors, experts and watch lovers from Italy and around the world also up +13%.
INDUSTRY AND TRAINING, PASSION MAKES A COMEBACK
Gold and jewellery see restored generational turnover in the labour market. Industry and education meet at Vicenzaoro: 23 schools at the Show, mostly from Italy and from France, Germany and the UK for a total of about 750 students and escorts, all involved in the many initiatives. In the VIOFF programme of city events, Vicenzaoro’s off-show, more than 490 students took part in the 20 events on the calendar.
THE EXPO CENTRE CHANGES FACE, 2024 IS THE YEAR OF WORK ON THE NEW HALL
The close of Vicenzaoro January 2024 will mark the opening of the building site that will return a new layout to the Vicenza Expo Centre for the September 2026 edition. The new 22,000-square-meter hall will replace Hall 2, the historic “snail” built in 1971, and Hall 5, to provide more space for exhibitors and better “navigability” for visitors inside the building. The investment of about 60 million euros is fully financed by IEG.
“THE VICENZA SYMPOSIUM”, THE NEW EVENT ON IEG’S JEWELLERY AGENDA
Italian Exhibition Group’s Jewellery Agenda will be further enriched as of 2025 with a new international event, “The Vicenza Symposium” scheduled to take place from 2 – 4 September. Vicenza will therefore inherit the scientific legacy of the “Santa Fe Symposium” which closed in 2022. A biennial event with a problem-solving approach for companies, the Symposium is the result of IEG’s collaboration with two leading companies in the T.Gold world: Legor and Xolutions.
GLOBAL STAKEHOLDERS AND INSTITUTIONAL PARTNERS
Vicenzaoro January confirmed its role as an international reference point due to the presence of the entire institutional and association world. From Confindustria Federorafi, Confartigianato Orafi, Confcommercio Federpreziosi, CNA Orafi, Confimi Industria Categoria Orafa ed Argentiera to Assogemme, Assocoral and A.F.E.M.O. – Association of Jewellery Machinery Manufacturers and Exporters, CIBJO – World Jewellery Confederation, Ministry of Foreign Affairs and International Cooperation, ITA – Italian Trade Agency.

The Science Behind Sparkle: How Lab-Grown Diamonds Are Created
A New Era of Diamond Creation
In recent years, lab-grown diamonds have captured the attention of jewellers, consumers, and investors alike. Beyond their beauty, what makes these gems truly fascinating is the science behind their creation. Unlike imitation stones, lab-grown diamonds share the same physical, chemical, and optical properties as natural diamonds — the only difference lies in their origin.
At the heart of this innovation are two cutting-edge processes: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These methods recreate the intense conditions under which natural diamonds form deep within the Earth, allowing scientists to produce genuine diamonds in a controlled laboratory environment.
HPHT: Diamonds Born Under Extreme Conditions
The High Pressure High Temperature (HPHT) method mimics the natural diamond-forming process that occurs about 150 kilometers below the Earth’s surface.
- Starting Point – The Seed:
A small diamond seed, usually a thin slice of an existing diamond, is placed inside a carbon-rich chamber. - Simulating Nature – Pressure and Heat:
The seed is exposed to extreme conditions — pressures of about 5–6 GPa (equivalent to the pressure at the Earth’s mantle) and temperatures of 1,400–1,600°C. - Crystal Growth:
Under these conditions, the carbon source melts and crystallizes around the diamond seed, forming a larger crystal over several weeks.
The result is a high-quality diamond crystal that is virtually indistinguishable from its natural counterpart. HPHT diamonds often exhibit exceptional clarity and can be produced in a range of sizes and colors, including colorless, yellow, and blue varieties.
CVD: Diamonds Grown in a Plasma Cloud
The Chemical Vapor Deposition (CVD) process is a more recent innovation that uses advanced plasma technology to grow diamonds atom by atom.
- Preparing the Chamber:
A thin diamond seed is placed inside a vacuum chamber filled with carbon-rich gases, typically methane and hydrogen. - Creating Plasma:
The gases are energized using microwaves or lasers, forming a plasma cloud that breaks down the molecular bonds of the gases. - Diamond Formation:
Carbon atoms released from the plasma settle onto the seed layer, crystallizing into pure diamond over the course of several weeks.
The CVD method allows for greater control over purity, color, and size, making it ideal for high-end jewellery applications. It also produces diamonds that are free from many of the inclusions typically found in natural stones.
Technology Meets Sustainability
Both HPHT and CVD processes are transforming the jewellery industry not only through technology but also through sustainability. Lab-grown diamonds require no mining, dramatically reducing environmental impact. Many manufacturers are also transitioning to renewable energy sources to power their production facilities, making these diamonds even more eco-conscious.
Furthermore, traceability is a defining advantage. Every lab-grown diamond can be tracked from its creation, offering complete transparency — a growing priority among modern consumers seeking ethical luxury.
Crafting the Future of Jewellery
As consumer awareness grows, lab-grown diamonds are redefining what it means to own something precious. With their scientific precision, sustainable creation, and stunning beauty, they represent the perfect harmony between innovation and artistry.
