Our scientific approach to testing ensures Accuracy, Authenticity, & Trust
Microscope Testing
Revealing Internal Characteristics with Precision
Microscope testing is the first step in identifying gemstones and Rudrakshas. Using high-magnification instruments, we closely examine surface features, inclusions, and internal structures. This helps distinguish natural stones from synthetic or treated ones, and verify the authenticity of Rudrakshas based on their natural mukhis and seed patterns.
Specific Gravity
Determining Density to Identify Authenticity
Specific Gravity (SG) testing measures the density of a gemstone or Rudraksha in comparison to water. This process helps identify the material by comparing its weight-to-volume ratio with standard values. SG testing is especially useful in detecting imitations and confirming the natural origin of gems and beads.
Refractive Index
Measuring Light Behavior for Accurate Identification
Refractive Index (RI) testing analyzes how light bends as it passes through a gemstone. Every mineral has a unique RI value, making this test one of the most reliable methods for gemstone identification. By using a refractometer, we can accurately differentiate between similar-looking stones and confirm their authenticity.
Color Testing
Analyzing Natural and Treated Colors with Precision
Color plays a vital role in the value and identity of gemstones and Rudrakshas. In color testing, we evaluate the hue, tone, and saturation of each item under controlled lighting conditions. This helps us detect any artificial enhancements or treatments and ensures that the natural beauty and originality of the specimen are verified.
Size Measurement
Precise Dimensions for Accurate Classification
Size measurement involves accurately determining the length, width, diameter, and weight of gemstones and Rudrakshas using calibrated tools. Proper sizing is essential for grading, certification, and fitting purposes. At CGTL, we ensure every item is measured with precision to maintain consistency and trust in our reports.
