Kitco Gold Price and Charts Data

The most-watched spot screen in precious metals, captured field by field. One live record carries the full quote: bid and ask in US dollars per troy ounce, change and percent change against the prior close, the session's day range, and the same bid restated across six units of measure from gram to tael. Around it sits a purity table turning spot into 24K, 22K, 18K, 14K and 10K per-ounce jewellery values, twelve currency variants of the identical quote, and chart history selectable by month and year back to roughly 1999.

Two things lift this record above a headline number. First, the spread: at observation on 21 August 2026 the bid sat at 4,587.40 and the ask at 4,589.40 - a $2.00 window between what a buyer pays and a seller receives. Second, the purity conversion, which plain price histories simply do not offer: an 18K valuation of 3,440.55 per ounce falls straight out of the 4,587.40 bid, ready for any scrap-value or jewellery-margin calculation.

One session snapshot, exactly as a sample arrives:

observed        2026-08-21
bid             4,587.40  USD/oz
ask             4,589.40  USD/oz
spread              2.00  USD
change           +69.20   (+1.53%) vs prior close
day's range   4,508.30 - 4,605.60  USD/oz
per gram         147.49  USD/g
per kilogram  147,490.60 USD/kg
18K value      3,440.55  USD/oz

Reading the row: every downstream figure derives from one bid, and the arithmetic checks out to the penny - 4,587.40 divided by 31.1035 troy ounces per kilogram lands on 147.49 per gram, times a thousand back to 147,490.60, and three-quarters of the bid reproduces the 18K row exactly. The day range spans $97.30, about 2.1% of spot, marking a session with real movement rather than drift. Each field repeats on every capture, so a parser written once reads every future snapshot.

Ten core fields on the live record, all observed and typed during the August 2026 review. The dictionary below carries definitions and worked examples; the remainder folds into deliveries on request.

• Geography - a global spot reference quoted in US dollars, with eleven further currency views so regional desks read the identical quote natively: CAD, EUR, GBP, AUD, JPY, CHF, CNY, HKD, INR, BRL, MXN and ZAR.
• Temporal - live intraday values alongside historical charts selectable by month and year back to roughly 1999, about twenty-seven years of charted history; archive depth varies somewhat by currency.
• Granularity - tick-level on the live quote and daily-or-coarser across the historical archive, so intraday work and long-horizon work pull from the same record without schema changes.

API, files, or your warehouse. Daily, weekly, or hourly.

• Jewellery, pawn and scrap pricing - the purity table converts one bid into five karat-level valuations instantly; at 4,587.40 spot, an 18K piece carries 3,440.55 per troy ounce of metal content before any maker's premium. Worked pricing flows continue on our price monitoring page.
• Quant and macro research - the live bid with its spread and day range slots into event studies and cross-asset work where a settlement-only series leaves the intraday story untold; backtesting workflows pair it with longer history from quant backtesting.
• Treasury and procurement teams - twelve currency views mean a buyer settling in rupees or rand reads the same market natively instead of layering an FX conversion over a dollar quote.
• Market researchers and consultants - the multi-unit ladder (ounce, gram, kilo, pennyweight, tola, tael) maps cleanly onto regional trade conventions, from Asian tola quotations to Turkish ese; see market researchers for the fuller workflow.
• Journalists and students - a quotable, timestamped spot level with its own day range beats citing a round number from memory.

Investors and quant researchers get a live bid-ask pair with session context - the $2.00 spread observed on 21 August 2026 is execution-relevant information a close-only series hides; workflows continue on our investors and quants in gold page. Data scientists and ML engineers get a compact, fully numeric record whose ten core fields arrive typed and consistent, ideal as a live feature alongside deeper histories; see data scientists in gold. Developers and data-product builders get the purity table as structured values rather than a screenshot, so karat pricing ships inside their own product; see developers and builders in gold. Journalists, academics and students get a citable, dated spot observation with its full range rather than an approximation; see journalists and academics in gold.

Four notes travel with this page - the currency breadth, the purity table, the unit ladder and the charting depth - and each one earns its place on a build, not a brochure. Skim them below, then request a sample cut to your markets and cadence.
