Understanding Platinum Valuation

Calculating the value of platinum jewelry or bullion requires understanding the specific metallurgy of the item. Unlike simple multiplication of weight by market price, platinum valuation involves the "fineness" or purity of the alloy, which significantly impacts the final value.

Platinum is rarely used in its 100% pure form for jewelry because it is too soft. It is alloyed with other metals from the platinum group (like iridium, palladium, or ruthenium) or base metals (like copper or cobalt) to increase durability.

Common Platinum Purity Standards

  • Pt950 (95% Pure): The most common standard for high-end jewelry and engagement rings. It contains 950 parts platinum per 1000 parts.
  • Pt900 (90% Pure): Often used in settings where slightly more hardness is required.
  • Pt850 (85% Pure): Generally the minimum purity standard for an item to be sold as "Platinum" in many jurisdictions.
  • Pt999 (99.9% Pure): Used primarily for investment coins and bullion bars, not typically for wearable jewelry.

How This Calculator Works

To determine the accurate price of your platinum item, this calculator follows the standard industry formula:

  1. Determination of Pure Weight: We multiply the total weight of your item by the purity factor (e.g., 0.950 for Pt950).
  2. Base Value Calculation: The pure weight is multiplied by the current market spot price per gram.
  3. Making Charges: For jewelry, a percentage is added to cover the craftsmanship and labor. Platinum is denser and has a higher melting point than gold, making it more difficult and expensive to work with.
  4. Taxation: Finally, any applicable local taxes (Sales Tax, VAT, or GST) are applied to the subtotal.

Platinum vs. Gold Pricing

While gold prices are often quoted in Karats (24K, 18K), platinum uses parts per thousand. Additionally, platinum is significantly denser than gold. A ring made of platinum will weigh approximately 40% more than the exact same ring made of 18K gold. Therefore, even if the price per gram is similar, the platinum piece will often cost more due to the heavier weight required.

function calculatePlatinumValue() { // Get Inputs var pricePerGram = parseFloat(document.getElementById('ptPricePerGram').value); var weight = parseFloat(document.getElementById('ptWeight').value); var purity = parseFloat(document.getElementById('ptPurity').value); var makingChargesPercent = parseFloat(document.getElementById('ptMakingCharges').value); var taxPercent = parseFloat(document.getElementById('ptTax').value); // Validation if (isNaN(pricePerGram) || isNaN(weight) || pricePerGram <= 0 || weight <= 0) { alert("Please enter a valid Market Price and Weight."); return; } // Handle defaults for optional fields if (isNaN(makingChargesPercent)) makingChargesPercent = 0; if (isNaN(taxPercent)) taxPercent = 0; // 1. Calculate Pure Content // Purity is usually out of 1000 (e.g., 950) var purityFactor = purity / 1000; var pureWeight = weight * purityFactor; // 2. Calculate Base Value // The market price is usually for PURE platinum. // So we multiply the pure weight by the market price. var baseValue = pureWeight * pricePerGram; // 3. Calculate Making Charges // Making charges are calculated on the base value of the metal usually var makingChargesAmount = baseValue * (makingChargesPercent / 100); // 4. Calculate Subtotal and Tax var subTotal = baseValue + makingChargesAmount; var taxAmount = subTotal * (taxPercent / 100); // 5. Total var totalValue = subTotal + taxAmount; // Display Results document.getElementById('resPureWeight').innerText = pureWeight.toFixed(2) + " g"; document.getElementById('resBaseValue').innerText = baseValue.toFixed(2); document.getElementById('resMakingCharges').innerText = makingChargesAmount.toFixed(2); document.getElementById('resTax').innerText = taxAmount.toFixed(2); document.getElementById('resTotal').innerText = totalValue.toFixed(2); // Show the result box document.getElementById('ptResultBox').style.display = 'block'; }
