AI Item Analysis

This is an official GIA (Gemological Institute of America) Colored Diamond Grading Report, numbered 2235866703, dated February 18, 2026. The report pertains to a loose diamond characterized by a 'Square Emerald Cut' with physical dimensions of 3.79 x 3.78 x 2.94 mm. The stone weighs 0.42 carats. Its color is classified as 'Natural, Fancy Yellow' with an even distribution. The report details several technical proportions, including a 68% table size and a 77.6% total depth, featuring an 'extremely thick' polished girdle and no culet. Regarding finish, the polish is rated 'Good' and the symmetry is 'Very Good.' The stone exhibits faint fluorescence. Internal characteristics identified in the clarity assessment include feathers and an indented natural. The document itself is printed on specialized high-security paper with a textured watermark pattern and contains a detailed profile diagram of the stone. The craftsmanship of the report indicates authentic GIA certification, vital for the market valuation of high-end gemstones. The condition of the document appears excellent with no visible tears or stains, though it represents a future-dated report (2026).

AI Appraisal Report

Upon examination of the GIA report #2235866703, I have analyzed the market value for this 0.42 carat Fancy Yellow diamond. The 'Fancy Yellow' grade represents a desirable entry point into investment-grade colored diamonds, as it possesses distinct saturation without the extreme premiums of 'Intense' or 'Vivid' grades. The Square Emerald cut is a sophisticated step-cut that requires high clarity to remain attractive; while feathers and indented naturals are present, the 'Fancy' color saturation typically masks these better than in colorless stones. The 'Extremely Thick' girdle and 'Good' polish are slight detractors for light performance but are typical for fancy colors where cutters prioritize weight retention and color concentration. Market demand for yellow diamonds remains stable, particularly for stones with GIA certification which provides the gold standard for liquidity. Comparable sales for sub-half-carat fancy yellow diamonds range from $2,500 to $3,500 per carat, placing this stone's intrinsic value at approximately $1,100 to $1,400. This appraisal is based solely on the documentation provided. I cannot verify the physical existence of the stone or the authenticity of the report paper (watermarks, UV security features) without a physical inspection. A 10x loupe examination is required to confirm the 'natural' origin and match the internal inclusions to the GIA plot. Furthermore, the 2026 date suggests this is a forward-dated or projected report, which necessitates verification via the GIA Report Check digital database to ensure the data is not forged or altered.
