Key Takeaways
Diamond Quality Checks & Certification:
- Advanced treatments challenge LGD grading and certification accuracy.
- Key challenges: ensuring grading accuracy, standardization, and detecting undisclosed synthetics.
- Emphasis on advanced testing methods, tech-driven grading, and industry consistency.
- Traceability of tested items is a major issue.
- LGDs are both supplementary and complementary to the diamond industry.
- Mimicking natural diamond growth patterns in LGDs remains a challenge.
LGD Growth & Treatment Recipes: Key Takeaways
- Increasing nitrogen in HPHT accelerates growth, benefiting gem-quality diamonds but not other industrial uses.
- Focus on optimizing growth parameters, impurity control, and enhancement for superior diamonds.
- Challenges include consistency, reducing defects, scalability, and reliance on high-purity raw materials.
- Future focus on refining processes, improving sustainability, and enhancing research-industry collaboration.
Diamond Quality Checks & Certification (Continued): Key Takeaways
Strengthening quality assurance frameworks is essential to ensure consumer trust globally.
Grading LGDs differs from natural diamonds, especially in color; secondary reference masters needed.
Labs must assess hue saturation and intensity, not just color for LGDs.
Clarity characteristics differ due to metallic inclusions in LGDs.
Color grading challenges arise in borderline clusters where AI struggles.
LGDs are cut for perfection, unlike natural diamonds, which are cut for weight retention.

WGC Central Bank Gold Reserves Survey 2025

Central banks have accumulated over 1,000t of gold in each of the last three years, up significantly from the 400-500t average over the preceding decade. This marked acceleration in the pace of accumulation has occurred against a backdrop of geopolitical and economic uncertainty, which has clouded the outlook for reserve managers and investors alike.
2025 Central Bank Gold Reserves (CBGR) survey, conducted between 25 February and 20 May, helps us shine a light on the continued importance of gold reserve management in these challenging times. This year we set a new benchmark, drawing in 73 responses – the highest since our survey commenced eight years ago.
Key highlights
- Similar to findings from previous surveys, central banks continue to hold favourable expectations on gold. Respondents overwhelmingly (95%) believe that global central bank gold reserves will increase over the next 12 months.
- This year, a record 43% of respondents believe that their own gold reserves will also increase over the same period. Interestingly, none of our respondents anticipate a decline in their gold reserves.
- Gold’s performance during times of crisis, portfolio diversification and inflation hedging are some key themes driving plans to accumulate more gold over the coming year. In addition, gold’s unique characteristics and role as a strategic asset continue to be valued by central banks: its performance in times of crisis, ability to act as a store of value, and its role as an effective diversifier, continue to be cited as key reasons for an allocation to gold.
- The majority of respondents (73%) see moderate or significantly lower US dollar holdings within global reserves over the next five years. Respondents also believe that the share of other currencies, such as the euro and renminbi, as well as gold, will increase over the same period.
- The survey highlighted an uptick in respondents who actively manage their gold reserves, from 37% in 2024 to 44% in 2025. While enhancing returns remained the primary reason for this, risk management leapfrogged tactical trading as the second most selected reason.
- The Bank of England remains the most popular vaulting location for gold reserves amongst respondents (64%); a significantly higher percentage of respondents reported some domestic storage of gold reserves this year than they did last year (59% in 2025 vs 41% in 2024). Just 7% of respondents indicated that they plan to increase domestic storage of gold reserves over the next 12 months.
