No. GemGuide prices represent wholesale market benchmarks based on industry data. Nivoda’s listed prices are set by our curated network of suppliers and reflect the actual cost to purchase each gemstone. GemGuide pricing serves as a reference point to help you evaluate value.
Gemstones are natural products with variations in color, clarity, cut, and origin. GemGuide provides ranges to account for these quality differences within each category. This helps you understand the typical market spectrum for similar stones.
GemGuide updates its pricing regularly based on market movements. The publication releases updates every 2 months to reflect current market conditions, seasonal trends, and changes in supply and demand.
No. Unlike diamonds with standardized 4Cs grading, colored gemstones are evaluated differently. GemGuide uses quality descriptors and pricing categories that reflect how the colored gemstone industry actually trades, focusing on color, clarity, cut, and carat weight with gemstone-specific considerations like:
GemGuide uses a 1-10 rating scale to grade colored gemstones, divided into four broad quality categories: Commercial (1-4), Good (5-6), Fine (7-8), and Extra Fine (9-10). Each category is further refined as follows:
When you see a rating like “8” on Nivoda, this indicates “Upper Fine” quality. The rating is determined by starting with a color grade and then making deductions based on clarity (inclusions, transparency, color zoning), cut quality (brilliance, proportions, finish), and overall appearance. A rating of 8 represents a high-quality gemstone with excellent color, minimal clarity issues, and good cut quality—suitable for fine jewelry applications. This standardized grading helps you quickly assess gemstone quality and understand pricing differences across our inventory.
GemGuide pricing will be shown for gemstones within their coverage categories for Nivoda’s Curated Selection, which includes the most commercially traded colored gemstones. Some rare, unusual, newly listed gemstone varieties, or gemstones outside the ‘Curated Selection’ may not have GemGuide pricing benchmarks available on the Nivoda platform.
Use GemGuide as one component of your evaluation process. Compare Nivoda’s listed price against the GemGuide range while considering the gemstone’s specific quality grade, any premium characteristics (origin, treatment, exceptional color), current market trends, your target retail markup, and the gemstone’s suitability for your designs or customers. Remember that Nivoda’s prices reflect all-inclusive costs.
