What is smart fluctuation and why do you use it?

Smart fluctuation is a statistical algorithm that adds small fluctuations between base updates (every minute) to simulate real market movement. We use Linear Regression to analyze trends and Volatility to calculate fluctuations. These fluctuations are statistical estimates and do not represent actual trading prices.

Are the displayed prices real trading prices?

The base price updated every minute is a real price from Metal Price API. However, the fluctuations displayed between updates (every 0.8-7 seconds) are smart statistical estimates that simulate market movement and do not represent actual trading prices. All prices are indicative and the final price should be verified directly from the jewelry shop.

How often do you update prices?

We fetch base data from Metal Price API every minute. Between these updates, we display smart fluctuations every 0.8-7 seconds (depending on market activity) to provide an experience closer to real market movement.

Why do your prices differ from jewelry shops?

Our prices are indicative because we do not sell gold. Jewelry shops add profit margins, manufacturing and craftsmanship fees, and may update their prices only once or twice daily. Selling prices also differ from buying prices. We always recommend verifying the final price directly from the shop.

How do you calculate prices for different karats?

We calculate karat prices based on pure gold percentage: 24K = 100% of base price, 22K = 91.67% (22÷24), 21K = 87.5% (21÷24), 18K = 75% (18÷24). The base price is converted from USD to Saudi Riyal and from ounces (31.1035 grams) to grams.

We believe in complete transparency - learn how we collect and calculate gold prices accurately and professionally

Last Updated: May 04, 2026

Overview

Our Commitment to Transparency

At Zahab Price, we believe transparency is the foundation of trust. This page explains in detail how we collect, calculate, and display gold prices.

Zahab Price is an informational website that displays indicative gold prices across Arab countries, Europe, and the US. We use trusted global data sources with advanced statistical algorithms to provide an experience close to real market movement.

Data Source

Metal Price API

We obtain gold price data from Metal Price API (metalpriceapi.com), a specialized service for providing precious metal prices from commercial sources and global banks.

What Metal Price API says about their sources:

"Our data comes from commercial sources and global banks, with a greater focus on commercial sources to more accurately reflect live trading activities"

Update Frequency

Base Data

We fetch the latest prices from Metal Price API every minute. This price is the real base price on which all calculations are built.

Price Calculation Method

1. Base Price (USD/Ounce)

We obtain the raw gold price (24 karat) in US dollars per ounce from Metal Price API

2. Convert to Grams

We convert the price from ounces to grams:

Price per gram (USD) = Price per ounce ÷ 31.1035

3. Convert to Saudi Riyal

We multiply the price by the dollar to riyal exchange rate:

Price per gram (SAR) = Price per gram (USD) × Exchange Rate

4. Calculate Different Karats

We calculate karat prices based on pure gold percentage:

24K = Base Price × (24 ÷ 24) = 100%

22K = Base Price × (22 ÷ 24) = 91.67%

21K = Base Price × (21 ÷ 24) = 87.5%

18K = Base Price × (18 ÷ 24) = 75%

5. Bullion Prices

We add a reasonable profit margin for bullion based on weight (heavier bullion has lower margins)

Why Might Prices Differ from Jewelry Shops?

Profit Margin

Each jewelry shop adds its own profit margin based on location and expenses

Manufacturing and Craftsmanship Fees

Gold items include manufacturing fees that vary based on design and quality

Update Timing

Some shops update their prices only once or twice daily

Buying and Selling Policies

Selling prices differ from buying prices at jewelry shops

Important Tip

Use our prices as an indicative reference to know the general market trend, but always verify the final price directly from the jewelry shop before completing a purchase or sale.
