Quality Analysis
Our comprehensive quality analysis service provides detailed evaluation of gemstone characteristics following internationally recognized grading standards. We analyze cut, color, clarity, and carat weight for diamonds, and equivalent quality factors for colored gemstones, providing you with complete understanding of your stone's quality and market position.
Diamond Quality Analysis - The 4Cs
Cut Analysis
We evaluate how well a diamond's facets interact with light, measuring proportions, symmetry, and polish. Our analysis includes assessment of brightness, fire, and scintillation to determine the cut grade. We use advanced proportion analyzers and light performance imaging to provide precise cut quality evaluation that directly impacts the diamond's beauty and value.
Color Grading
Our color analysis follows the GIA color scale from D (colorless) to Z (light yellow or brown). We use controlled lighting conditions and master comparison stones to ensure accurate color determination. For fancy colored diamonds, we provide detailed color descriptions including hue, tone, and saturation analysis. Our color grading directly affects the diamond's rarity and market value.
Clarity Assessment
We examine diamonds under 10x magnification to identify and map inclusions and blemishes. Our clarity grading follows the GIA scale from Flawless to Included, documenting the size, nature, location, and relief of clarity characteristics. We provide detailed clarity plots showing the exact position of inclusions, helping you understand how clarity affects the diamond's appearance and value.
Carat Weight Measurement
We use precision electronic scales calibrated to 0.001 carat accuracy to determine exact carat weight. Our measurements are verified multiple times to ensure accuracy. We also calculate the diamond's dimensions and provide detailed measurements of length, width, and depth, along with total depth percentage and table percentage calculations that affect the stone's proportions and light performance.
Colored Gemstone Quality Analysis
For colored gemstones, we evaluate beauty, rarity, and durability factors. Our analysis includes color saturation and distribution, clarity characteristics specific to each gemstone type, cut quality and proportions, and carat weight. We also assess phenomena such as asterism, chatoyancy, or color change effects. Our colored stone analysis follows established protocols for rubies, sapphires, emeralds, and other precious and semi-precious stones.
Advanced Analysis Techniques
Our quality analysis incorporates the latest gemological technology including photomicrography for detailed inclusion documentation, spectroscopic analysis for treatment detection, proportion analysis for cut optimization recommendations, and light performance evaluation for beauty assessment. We also provide enhancement and treatment disclosure, origin determination when possible, and market positioning analysis based on current quality standards.
