Methodology Detail
How this index is built
Frequently asked questions on sourcing, citation, and refresh cycle.
How are sources verified?
Every statistic is cross referenced against the original publication. Where a claim appears in a secondary source citing a primary one, the primary publisher is named alongside the link. Statistics that cannot be verified through a public source are excluded.
How often is this index updated?
Quarterly. Each refresh adds new statistics from the past quarter and removes any that have been superseded. The next scheduled update is August 2026.
Can journalists cite individual statistics?
Yes. Each statistic has a permanent anchor ID. Use the format
dracodiamond.com/pages/lab-diamond-statistics-2026#stat-001 to deep link any specific data point. Attribution to Draco Diamond is appreciated but not required for the underlying source data.Why does Draco Diamond publish this index?
Draco Diamond Research Desk produces ongoing primary research on lab grown diamond pricing, markup, and grading variance. This index aggregates the most cited third party data alongside Draco's own published research to serve as a single reference for journalists, analysts, and consumers researching the category.
What currencies are used?
Each statistic is presented in the original publication's currency, marked USD or CAD where applicable. Where Draco's own pricing is referenced, all figures are CAD. Conversion uses 1 CAD = 0.73 USD as of February 2026.
Are competitor prices ever named?
Specific named retailer prices are referenced only where the source publication has documented and verified the figure. Aggregated tier groupings (e.g. "major US online retailers") are used for category level claims to avoid singling out individual brands without evidence.
How can readers report a correction?
Send a note to [email protected] with the statistic ID and the corrected source. All verified corrections are applied at the next quarterly refresh and acknowledged in the change log.
