Why Diamond Statistics?

Diamond statistics are part of the essential tools a business needs to better operate and understand the global diamond industry.

We collect, analyze, and make sense of diamond market data, such as wholesale lab grown diamond prices, diamond producing country exports, diamond centers’ international trade, and diamond mining companies’ annual production.

Lab Grown Diamond Prices

We collect transaction pricing for lab-grown diamonds, both retail and wholesale.

The wholesale prices are for loose, round-shaped, certified lab diamonds sold at diamond trading centers in Mumbai and Surat, India. We also release a quarterly lab-grown wholesale price list, which is available as a price chart.

The retail prices are collected weekly from a panel of 2,500 jewelry stores in the United States, the primary consumer market for lab-grown diamonds. The size of the panel, 10% of the US market, creates a very accurate diamond statistics data set. The retail data also includes retailers’ purchase costs, which are higher than wholesale trading prices. Our sister company, Tenoris, collects the retail data.

Wholesale Lab-Grown Diamond Price List

The wholesale lab-grown price list is based on transaction prices as traded by lab-grown diamond polishers, primarily in India, the main lab diamond trading center. The values are average transaction prices per carat of round, SI-VVS clarity, D-H color, IGI-certified loose lab-grown diamonds.

Prices are published on a quarterly basis and available at no charge.

Wholesale Lab-Grown Diamond Price Trend

The wholesale lab grown price trend data is collected in India, the main lab diamond trading center. The values are average transaction prices per carat of round, SI-VVS clarity, D-H color, IGI certified loose lab-grown diamonds.

Notes on the wholesale LGD price list:
Until Q2 2024, we reported transaction prices for round-shaped LGD in sizes ranging from 0.23 to 2 carats. These transaction prices were for fresh goods sold by manufacturers in parcels, and they represented lab diamonds’ lowest wholesale trading price.
Since then, and as the market has changed, we stopped publishing prices of lab-grown diamonds smaller than 1 carat and added 3 carats to the published size ranges. We also modified our methodology and began reporting wholesale prices for certified lab diamonds purchased in small transactions, which more accurately reflected changing market trends.
Historical lab-grown diamond prices are available upon request.

Retail Lab-Grown Diamond Price Trend

The retail lab-grown price trend data are actual consumer purchases collected from 2,500 US jewelry retailers. The values are consumers purchase prices per carat of round-shaped, SI-VVS clarity, D-M color, loose lab-grown diamonds. For more on this data and subscribing to Tenoris’ US retail data, contact us.

Notes on the retail lab-grown diamond price data:
Data is collected on a per-transaction basis since January 2020.
The large retailer panel, representing 5.5% of US jewelry demand and 10% of US specialty jewelers, offers very accurate diamond statistics basis.
Historical lab-grown diamond prices are available upon request.

Upstream Diamond Trade Statistics

Below are free annual diamond statistical sets relating to two key diamond activities: international trade and production.

The diamond statistics data was sourced from governmental agencies that track their international diamond trading activities, major mining companies engaged in diamond production around the world, and the Kimberley Process Certification Scheme.

Kimberley Process is an international, multi-stakeholder initiative created to increase transparency and oversight in the diamond industry. This is done in order to eliminate trade in conflict diamonds and rough diamonds sold by rebel groups or their allies to fund conflict against legitimate governments.

Following is data by country and company, followed by US Trade data, and then a map illustrating where diamonds are mined (produced).

Rough and Polished Diamond Trade Statistics by Country

Rough and polished diamond statistics: import and export trade data by the leading diamond manufacturing and trading countries. These eight countries are the leading diamond trading, manufacturing (polishing), and consuming countries.

Where Diamonds Are Mined

Diamonds are primarily mined in two bands around the globe: southern and northern. The southern band includes Southern Africa and Brazil.

The northern band includes diamond resources in Russia and Canada. In 2024, the largest diamond producing countries by value and volume were Russia, Botswana, and Angola.

Global Diamond Production 2024

Global diamond production increased 5.8% year-on-year to 118 million carats in 2024, according to Kimberley Process figures. The average value per carat of production fell 15% to $97, following a 16% drop in 2023 as global consumer demand continued to decline.

Due to this decline in diamond prices in 2024, the total value of production declined 10% year-on-year.

In the previous two years, the average value of production has crashed by 28%.
