CGL Expertise

ADVANCED XRF ANALYSIS

Advanced XRF Analysis provides precise insights into material composition, making it an essential tool for determining purity and elemental structure in metals like gold, silver, and platinum. It ensures accurate grading and quality assurance in the gem and jewelry industry.

MOLECULAR SPECTROSCOPY

Molecular spectroscopy, including FTIR, helps decode the molecular patterns of gemstones. It identifies treatments like resin filling in emeralds and polymer impregnation in jade, while also offering a reliable way to classify diamond types and detect enhancements.

PRECISION RAMAN TECHNIQUE

The Precision Raman Technique excels in gemstone identification, distinguishing natural stones from synthetics. It effectively differentiates between diamond simulants like moissanite and cubic zirconia, and is a trusted method for verifying jade quality.

ELEMENTAL DELTA SCANNING

Delta Scanning uses cutting-edge XRF technology to analyze the intricate composition of alloys, minerals, and other materials. Its high sensitivity allows for detailed evaluation of precious metal alloys and geological specimens.

Diamond Assessment Procedure

The assessment of diamonds involves a series of intricate steps to ensure accurate results. Each diamond undergoes detailed inspection based on industry standards, focusing on factors like shape, size, and polish. The primary attributes, including carat weight, clarity, and symmetry, are meticulously documented during this phase.

These evaluations demand precision and expertise, qualities exemplified by our skilled team at CGL. Once the diamond has been thoroughly examined, a comprehensive certification report is prepared. This report includes a unique Certificate ID, enabling users to access, download, or verify its authenticity online via our portal or SMS service.
