Introduction
For a current Rapaport price, check the latest weekly list for your diamond's weight, color, and clarity. The list gives a benchmark asking price per carat, not a guaranteed sale price. As a quick market check, the supplied RAPI monthly snapshot puts 0.30-carat diamonds at $938 per carat, down 3.45%, and 1.00-carat diamonds at $3,892 per carat, down 0.68%. Those index figures are separate from the price list and should not be treated as a live October 2026 quote.
The gap between a benchmark and an offer matters. A diamond's cut, grading, and demand can change what a buyer will pay; many stones trade below the list price. For a fair comparison, match the stone's details to the latest list, then check prices for similar diamonds in the market.
Whether you are looking to liquidate high-value jewelry or simply want to understand how professionals evaluate fine gemstones, navigating the wholesale benchmark is essential for true price transparency. The global diamond trade relies on standardized systems, primarily the Rapaport Diamond Price List and the Rapaport Diamond Price Index (RAPI™), to establish baseline values across the traditional 4Cs.
What Is the Current Diamond Rapaport Price List and How Does It Work?
First published in 1978 by Martin Rapaport, the Rapaport Diamond Price List fundamentally changed an opaque diamond industry by establishing a transparent, standardized wholesale pricing sheet. Prior to its inception, diamond pricing was largely arbitrary, guarded closely by closed networks of dealers. Today, the Rapaport Group serves over 21,000 members across 127 countries, and the benchmark is utilized by more than 20,000 diamond professionals globally.
The list represents high cash asking prices in New York wholesale trading. It does not represent an average retail price, nor does it guarantee what an end consumer will pay or receive. Instead, it acts as a universally recognized ceiling and baseline for negotiations among diamond cutters, manufacturers, wholesalers, and retail jewelers.
Published every week on Thursday at 11:59pm EST, the report relies heavily on strict grading standards, particularly verifying GIA diamond certification standards across clarity tiers and color grades. To maintain valuation integrity, stones graded on the list assume standard commercial proportions (often categorized into Spec A, B, and C cut criteria). When dealers and appraisers study how to calculate diamond price, the matrix on the Rapaport sheet provides the primary numeric baseline before secondary characteristics are factored in.
Carat Weight Bracket | Color Grade Range | Clarity Grade Range | Rapaport Matrix Function |
|---|---|---|---|
0.30 – 0.39 ct | D through M | IF through I3 | Sets baseline rates for small solitaire and accent stones |
0.50 – 0.69 ct | D through M | IF through I3 | Tracks high-volume commercial bridal diamond pricing |
1.00 – 1.49 ct | D through M | IF through I3 | Primary industry bellwether for classic 1-carat solitaires |
3.00 – 3.99 ct | D through M | IF through I3 | High-value luxury bracket with tighter wholesale availability |
5.00 – 5.99 ct | D through M | IF through I3 | Investment-grade and statement gemstone benchmark |
Reading the Current Diamond Rapaport Price Grid
Reading the current diamond rapaport sheet is straightforward once you understand its layout. The price sheet is divided into distinct grids based on carat weight brackets (for example, 0.50–0.69 ct, 1.00–1.49 ct, and so forth).
Within each grid:
The vertical axis displays color grades from D (completely colorless) down to M (faint tint), which you can reference by consulting the diamond color grades chart.
The horizontal axis displays clarity grades ranging from Internally Flawless (IF) through Imperfect (I1, I2, I3).
The intersecting cell contains a number expressed in hundreds of US dollars per carat.
To calculate the baseline price of a diamond:
Locate the correct weight bracket for your diamond.
Cross-reference its certified color row with its clarity column to find the matrix value.
Multiply that matrix number by 100 to determine the per-carat list price in US dollars.
Multiply the per-carat price by the diamond's actual carat weight.
For example, on historical lists such as the February 2, 2024 report, a 1.00–1.49 ct round brilliant diamond with D color and IF clarity was listed with a matrix value of 212 ($21,200 per carat), whereas a 0.50–0.69 ct stone of identical color and clarity held a value of 65 ($6,500 per carat).
How Discounts and Premiums Determine Actual Transaction Value
In practical wholesale trading, very few diamonds trade at 100% of the Rapaport list price. Because the list reflects high cash asking prices, most natural diamonds trade at discounts ranging between 10% and 30% below the list price, though poorly cut stones or undesirable proportions can trade at discounts of 40% or more. Conversely, exceptionally rare stones with perfect cut parameters, zero fluorescence, and exceptional luster may trade at narrow single-digit discounts or even slight premiums.
Key factors influencing whether a diamond trades at a steep discount or near the benchmark include:
Cut Proportions, Polish, and Symmetry: A triple-excellent GIA cut stone commands far higher pricing than a diamond with fair symmetry or a thick girdle.
Fluorescence: In high color grades (D through F), medium to strong blue fluorescence often triggers discounts of 5% to 20% due to potential haziness under direct sunlight.
Inclusion Type and Location: Black inclusions directly under the table facet or open feather inclusions on the girdle reduce wholesale desirability.
Understanding these trade realities is essential when understanding the diamond price guide for 2026 and setting realistic expectations for secondary market settlements.
Current Diamond Rapaport Trends and 2026 RAPI Index Movements
The natural diamond market in 2026 reflects shifting global supply dynamics and changing consumer demand. The Rapaport Diamond Price Index (RAPI™), which tracks real-time wholesale asking prices across major trading hubs, provides valuable visibility into market sentiment.
Recent monthly RAPI™ index figures across primary carat categories highlight these trends:
0.30 Carat Stones: Valued at $938 per carat, reflecting a monthly decline of 3.45%.
0.50 Carat Stones: Valued at $1,307 per carat, posting a minor decline of 0.83%.
1.00 Carat Stones: Valued at $3,892 per carat, showing stability after a small dip of 0.68%.
3.00 Carat Stones: Valued at $18,213 per carat, advancing with a 0.29% gain.
Industry analysts reviewing analysis of the 2026 RAPI rebound have noted that larger, high-quality natural diamonds have demonstrated greater price resilience. While smaller commercial melee and sub-carat diamonds have faced inventory build-up, premium 2-carat and 3-carat categories benefit from mining constraints and steady global luxury appetite, consistent with historical 3 carat round diamond price behavior.
Impact of Lab-Grown Diamonds on Natural Diamond Benchmarks
The explosive increase in lab-grown diamond manufacturing capacity (primarily Chemical Vapor Deposition and High-Pressure High-Temperature methods) has altered the entry-level jewelry landscape. Lab-grown wholesale and retail prices have dropped significantly—falling between 70% and 96% from their historic highs—due to continuous production scaling.
This sharp price divergence has led to distinct market segmentation:
Lab-grown diamonds now dominate lower-priced fashion jewelry and entry-level engagement ring sales.
Natural diamonds are increasingly viewed as distinct luxury assets with inherent scarcity, backed by initiatives focused on safeguarding natural diamond market prosperity.
When comparing lab grown vs natural diamond value, the wholesale secondary market treats the two categories entirely differently: natural diamonds retain measurable secondary liquidity based on Rapaport metrics, while lab-grown stones face steep secondary depreciation due to negligible replacement costs.
Round Brilliant vs. Fancy Shape Benchmark Pricing
While round brilliant diamonds represent the vast majority of trading volume and have their own weekly price list, fancy shapes (such as pears, ovals, emeralds, and cushions) have distinct pricing dynamics published in monthly specialized reports.
Historically, fancy shapes trade at a baseline discount compared to round brilliant cuts of identical carat, color, and clarity. However, specific cuts experience strong cyclical demand:
Oval and Pear Cuts: Elongated shapes remain in strong demand for modern bridal rings. Market data on pear-shaped diamond pricing shows that as of January 10, 2025, a 1.00–1.49 ct D/IF pear was listed at $9,300 per carat (matrix notation 93), compared to $21,200 per carat for an equivalent round brilliant.
Marquise Cuts: Supply shortages in well-proportioned marquise diamonds have narrowed their typical discount bands.
Cut Premium: Well-cut fancy shapes command substantial premiums over poorly shaped stones that suffer from prominent "bow-tie" extinction effects.
When evaluating brilliant cut diamond price variations, buyers and sellers must always reference the specific shape-dedicated benchmark list rather than applying round brilliant numbers directly to fancy cuts.
How to Calculate Fair Market Value Using Rapaport Tools and Market Data
Accurately determining the fair market liquidation value of a diamond requires combining benchmark sheets with real-time trading data. Professional dealers use sophisticated tools to track transaction prices across global diamond bourses.
The primary tools include:
Rapaport Diamond Price Calculator: A digital interface allowing users to input carat weight, color, clarity, and shape to instantly calculate total list value.
Rapaport TradeScreen: A tool that analyzes live buy-and-sell listings across more than 1.5 million natural diamonds listed on Rapaport Trade (formerly RapNet), providing the real-time average discount percentages currently being transacted for identical stone profiles.
Automated Inventory Pricing APIs: Wholesale systems that integrate weekly CSV and DBF pricing files to recalculate inventory values instantly each Thursday night.
For private individuals, using a diamond pricing calculator provides a reliable starting baseline. When asking yourself "how much is my diamond worth", wholesale transaction data forms the foundation from which any legitimate resale offer is derived.
Evaluating Resale Spreads and Wholesale Margins
There is an understandable difference between retail showroom replacement prices, wholesale benchmark rates, and secondary cash liquidation offers. Retail jewelry stores carry high operational overhead, custom setting costs, marketing expenses, and retail markups (often traditional "keystone" markup, which doubles wholesale cost, or higher in luxury brand showrooms).
For example, a high-spec 1.00-carat natural diamond (G color, VS1 clarity, Excellent cut) might trade on the wholesale market for around $3,800 to $4,500 after standard trade discounts. In international markets like South Africa, the same loose stone sells for roughly R72,000 to R92,000 including VAT, while finished showroom rings can retail for R105,000 to over R400,000 depending on branding and mounting complexity.
When an individual sells a diamond back into the secondary trade:
The buyer must evaluate the loose diamond based on its immediate wholesale liquidation value (Rapaport benchmark minus prevailing dealer discounts).
The mounting is typically valued separately based on its precious metal scrap weight.
Before selling, estimating return with a diamond resale value calculator and analyzing diamonds as a store of value helps individuals understand these wholesale spreads and avoid unrealistic retail price expectations.

Frequently Asked Questions About Current Diamond Rapaport Pricing
How often is the current diamond rapaport price list updated?
The Rapaport Diamond Price List is updated weekly every Thursday night at 11:59pm EST. Subscribers receive real-time digital access to price adjustments across round brilliant diamonds, while specialized fancy shape reports are updated monthly. Price changes reflect shifting wholesale transaction volumes, supply constraints, currency movements, and macroeconomic sentiment.
Why do diamonds sell below the current Rapaport benchmark?
The Rapaport list is structured around high cash asking prices rather than realized average sales. Most diamonds trade between 10% and 30% below the published benchmark in standard wholesale channels. Stones with lower cut grades (such as Fair or Poor symmetry/polish), visible inclusions under the table, or medium-to-strong fluorescence trade at steeper discounts to reflect the additional time and discounting needed to sell them.
How do lab-grown diamonds affect current natural diamond values?
Lab-grown diamonds have established a separate, lower-tier market segment. Because manufacturing improvements have lowered production costs significantly (with prices dropping 70% to 96%), lab-grown stones are priced primarily on factory output costs rather than the Rapaport natural diamond matrix. While lab-grown alternatives have reduced natural diamond demand in smaller sizes and fashion jewelry, certified natural diamonds maintain distinct wholesale secondary market value.
