💍 Jewellery Price Calculator (Delhi Market)

A React-based jewellery price calculator that estimates gold and silver jewellery prices for the Delhi market, using live bullion prices and real-world jewellery pricing models.

Unlike basic price trackers, this project focuses on how jewellery is actually priced in India, not just raw international rates.

🧠 Pricing Model Explained (Important)

Jewellery prices in India do not equal international spot prices.

This app uses a two-layer pricing model:

1️⃣ Live Bullion Spot Price

• Fetched from GoldAPI
• Represents the global raw metal price

2️⃣ Delhi Jewellery Market Adjustment

A calibrated multiplier is applied to reflect how bullion reaches the Indian retail market, accounting for:

• Import duties
• GST
• Banking & wholesaler premiums
• Jeweller margins
• Delhi-specific demand

This anchors the base price close to real Delhi market rates (e.g. Goodreturns, jeweller quotes).

3️⃣ Jewellery-Specific Adjustments

• Purity conversion
  • 24K → 100%
  • 22K → 91.6%
  • 18K → 75%
• Weight (grams)
• Making charges (%)

This approach produces prices that are realistic and comparable to Delhi jewellery prices, not just theoretical bullion values.

💡 Why This Project?

Most jewellery price apps simply display raw gold prices per gram, which does not reflect how jewellery is priced in India.

This project demonstrates:

• API integration in a frontend app
• Domain understanding of Indian jewellery pricing
• Practical modelling of spot vs retail prices
• Clean React state and logic separation

It prioritizes real-world reasoning over blind data usage.

📍 Future Improvements

• Spot vs Retail pricing toggle
• City-based pricing (Mumbai, Chennai, etc.)
• Historical price trends
• Deployment with live demo link
