South African Diamond Price Report 2026

South African diamond price report May 2026: the canonical per-carat ZAR reference for wholesale and retail across natural and lab-grown stones, with raw CSV and the seven-year price-collapse chart.

Correction, 19 October 2026: earlier versions said the bands were converted from the Rapaport and Idex lists at R18.50 to the dollar, that the retail figures came from anonymous walk-in enquiries, and that natural prices held steady. The SARB average for May 2026 was R16.48, Rapaport’s 1-carat index fell about 47 percent from its 2022 peak, and the bands are this column’s estimates, not list prices or observations.

Headline numbers, May 2026

Four numbers anchor the SA diamond market in May 2026: the dollar price per carat for a 1.00ct G/VS2 Excellent GIA round-brilliant, the ZAR/USD rate, the Bedfordview wholesale band, and the retail-channel markup. Everything else follows from these. The bands are this column’s estimates, not quotes or survey results.

The 1.00ct “magic carat” threshold adds 15 to 25 percent to per-carat price over a 0.90ct stone at otherwise-identical spec, reflecting psychological demand at the round-number weight. Sub-1.00ct stones (0.92ct to 0.98ct) deliver visibly identical finger presence at meaningful saving.

The 2019 to 2026 lab-grown collapse

Lab-grown wholesale fell from about R55,000 in 2019 to about R10,000 in May 2026 on this column’s estimates, the tail of an about 90 percent collapse since 2016. Natural fell too, but far less: Rapaport’s 1-carat RAPI index dropped about 47 percent from its 2022 peak to September 2026.

SA wholesale, 1ct G/VS2 Excellent lab-grown: this column's estimates, 2019 to May 2026 Lab-grown wholesale fell from about R55,000 in 2019 to about R10,000 in May 2026 on this column's estimates, the tail of an about 90 percent collapse since the 2016 peak, driven by global CVD and HPHT production capacity additions.

Lab-grown fell from about R55,000 to about R10,000 on this column’s estimates, the tail of an about 90 percent collapse since 2016. Natural prices fell far less: Rapaport’s 1-carat RAPI index is down about 47 percent from its 2022 peak. Download raw data (CSV).

The drivers, in order: CVD capacity additions in India and China through 2020 to 2022, a major diamond miner’s 2024 exit from its lab-grown jewellery brand signalling structural acceptance of lab-grown as the entry-tier category, and IGI lab-grown grading volume surpassing GIA natural grading volume in 2023. The natural wholesale price has also fallen in US dollars since 2022; rand-converted figures move with that and with the ZAR/USD exchange rate.

Channel markup: wholesale vs retail

Same physical 1.00ct GIA G/VS2 Excellent stone, moving through the SA channel chain in May 2026:

1.00ct GIA G/VS2 Excellent, channel markup chain, May 2026 (this column’s estimates).
ChannelTypical ZARMarkup over wholesale floor
Dealer reference price, rand-convertedR75,000 to R110,0000 percent (the reference floor)
Bedfordview manufacturer-direct, on appointmentR78,000 to R115,0003 to 6 percent
Mid-tier independent retail (Hyde Park, Rosebank)R140,000 to R210,00080 to 100 percent
Chain mall retail (Sandton, V&A Waterfront)R200,000 to R285,000140 to 200 percent
Tourist-tier (cruise ports, airport)R250,000 to R380,000200 to 300 percent

The markup at each layer funds different costs: chain retail funds the prime mall lease, the trained staff, the brand marketing, the in-store financing. Tourist-tier funds short-stay impulse-purchase capture. Bedfordview wholesale funds workshop overhead and dealer margin only. None of these channels is dishonest; they price different products with different cost stacks.

City-by-city retail estimates

Retail markup varies by SA city, driven by lease costs, foot traffic, and tourist exposure. The 2026 pattern:

Same 1.00ct GIA G/VS2 EX stone across SA retail layers, May 2026 (this column’s estimates, not observed quotes).
City / ClusterTypical chain retail ZARNotes
Sandton (Sandton City, Hyde Park, Mall of Africa)R200,000 to R285,000Highest mainstream retail. Lease-driven.
V&A Waterfront, Cape TownR215,000 to R310,000Tourist premium adds 5 to 10 percent over Sandton.
Pretoria (Brooklyn Mall, Menlyn Park)R175,000 to R245,0005 to 15 percent below Sandton.
Durban (Gateway, Pavilion)R170,000 to R235,000Lower mall lease costs.
Mid-tier independent (Hyde Park, Rosebank, Melrose Arch)R140,000 to R210,000Lower brand premium, same wholesale source.
Bedfordview manufacturer-directR78,000 to R115,000Wholesale floor. Appointment only.

Certificate effect on price

The certificate-issuing laboratory materially affects the price band even when the printed 4Cs are identical. SA market in May 2026:

Certificate effect on wholesale price, 1.00ct G/VS2 Excellent printed spec, May 2026 (this column’s estimates).
CertificateWholesale bandDiscount to GIA
GIA (the reference)R75,000 to R110,0000 percent (baseline)
IGIR65,000 to R95,00010 to 15 percent
EGLR52,000 to R78,00025 to 30 percent
SGLR55,000 to R82,00020 to 28 percent
In-house dealer reportR42,000 to R68,00040 to 50 percent

EGL grading is widely understood in the SA trade to run 1 to 2 grades looser than GIA at the same printed colour and clarity: a G/VS2 on EGL frequently grades H/SI1 if sent to GIA. Other non-GIA reports trade at a discount because they carry less international weight. The bands in this table are this column’s estimates.

Methodology and sources

The wholesale and retail bands are this column’s estimates for each stated specification in May 2026. They are not quotes, survey results or readings of the Rapaport (RapNet) or Idex lists, which are subscription products. Dollar equivalents use the SARB average rand-dollar rate for May 2026, R16.48 (daily range R16.27 to R16.76).

Corrected 19 October 2026: earlier versions said the bands were converted from the Rapaport and Idex lists at R18.50 to the dollar and that the retail figures came from anonymous walk-in enquiries at four shopping centres. Neither was right, and both statements have been removed.

The 2019 to 2026 historical series for the lab-grown wholesale tape uses annual averages from the Rapaport and Idex lab-grown reports, converted at the SARB monthly average ZAR/USD for that year.
