Key advancements in XRF focus on using high-resolution synchrotron-based techniques for trace element analysis
The diamond market is seeing mixed activity across the globe, driven by holiday shopping in the US and traditional shutdowns in India.
Recent advances in XRF in diamonds focus on using high-resolution, synchrotron-based techniques for trace element analysis, chemical state analysis of impurities, and identifying synthetic diamonds. Developments include using XRF with other techniques like X-ray absorption spectroscopy (XAS) for more complete analysis and using nanoprobes for spatial resolution down to 50 nm. Researchers are also creating methods to analyze trace elements in synthetic diamonds with high precision, sometimes achieving concentrations far greater than in natural diamonds.
Key advancements
- High-resolution spatial mapping:
Synchrotron XRF, especially with nanoprobe techniques, provides nanoscale mapping of elemental distributions within a diamond, revealing the relationship between elements and growth sectors.
Using techniques like XANES (X-ray Absorption Near Edge Structure) spectroscopy alongside XRF, researchers can determine the chemical state and site of impurities within the diamond lattice (e.g., the location of nickel atoms).
- Analysis of synthetic diamonds:
XRF is crucial for characterizing synthetic diamonds, including:
- Trace element analysis: Detecting and quantifying trace impurities (like Co and Mn) incorporated from metallic solvents used during synthesis.
- Synthetic vs. natural identification: Identifying synthetic diamonds based on their trace element composition, which differs from natural diamonds.
- Detecting intentional doping: Synthesizing and analyzing diamonds with specific doped atoms, like Europium (Eu), to achieve high concentrations (e.g., 51 ± 5 ppm) for specific properties.
- Integration with other techniques:
XRF is increasingly combined with other techniques like X-ray diffraction (XRD) and XAS to provide more comprehensive elemental and structural information about the sample.
- Gemological applications:
In the gemological industry, XRF is used to distinguish natural from synthetic diamonds and to detect treatments like fracture filling by showing the elemental composition of the filling agents.

Bhima Gold Unveils Ashtalakshmi Coin Collection for Akshaya Tritiya, Blending Devotion with Exquisite Design
A culturally rooted, insight-led launch that reimagines festive gold buying through storytelling, symbolism, and spiritual relevance.
In a move that blends cultural storytelling with product innovation, Bhima Gold has unveiled its Ashtalakshmi Coin Collection for Akshaya Tritiya – positioning gold not just as a purchase, but as a deeply symbolic expression of prosperity, faith, and intent.
Timed with one of India’s most significant gold-buying occasions, Akshaya Tritiya, the launch reflects a deeper cultural shift in consumer behaviour. While the festival continues to drive strong purchase intent, there is a growing preference for meaningful, purpose-led buying experiences over purely transactional consumption.
Aligned with this evolving mindset, the Ashtalakshmi coin collection has been thoughtfully conceptualised to blend tradition with deeper symbolism. Inspired by the eight sacred forms of Goddess Lakshmi, each coin represents a distinct dimension of prosperity—from wealth and nourishment to courage, knowledge, and continuity.

By bringing together Adi Lakshmi, Dhana Lakshmi, Dhanya Lakshmi, Gaja Lakshmi, Santana Lakshmi, Veera Lakshmi, Vijaya Lakshmi and Vidya Lakshmi, the collection reframes gold coins from being a generic festive purchase to a story-driven, culturally immersive product experience – one that resonates across generations and belief systems.
This launch also aligns with Bhima Gold’s larger centenary narrative of “Together Purever,” which focuses on legacy, shared traditions, and evolving consumer meaning. The collection becomes an extension of that philosophy – reinforcing how heritage brands are reinterpreting tradition for a more aware and emotionally driven consumer.
Customers can pre-book their favourite jewellery by paying just 10% in advance & get their jewellery on Akshaya Tritiya at the lowest rate, which gives customers more flexibility and helps them plan their purchases with greater confidence, especially at a time when gold prices are high.
Akshaya Tritiya has traditionally been associated with intention, belief, and the aspiration for prosperity, extending beyond a purely transactional act of buying gold. The Ashtalakshmi Coin Collection has been conceptualised to reflect this deeper cultural and spiritual significance, with each coin designed to carry a distinct meaning and sense of purpose. The initiative also aligns with evolving consumer preferences, where there is a noticeable shift towards jewellery that offers emotional, cultural, and spiritual resonance in addition to intrinsic value.
With gold prices near record highs and consumer sentiment becoming more considered, Bhima’s Ashtalakshmi Coin Collection signals a broader shift in the category — from price-led promotions to meaning-led engagement, where design, storytelling, and cultural relevance drive both differentiation and demand.
As legacy brands navigate a new era of conscious consumption, Bhima Gold’s latest offering highlights how tradition can be reimagined as experience, making gold buying not just an act of investment, but an expression of identity and belief.
