Starting a diamond business in India is a smart move, as the country dominates the global diamond cutting and polishing market. With over 75% of the world’s diamonds processed in hubs like Surat, India exports billions worth of polished stones annually. The industry is backed by skilled artisans, strong global demand, and government-supported infrastructure.

Historically, India was home to famous gems like the Kohinoor, and today it continues that legacy with leading firms like Kiran Gems and Hari Krishna Exports. Whether you’re launching a retail brand or an online venture, India’s deep-rooted expertise and global reputation make it an ideal place to shine in the diamond trade.

How to Start a Diamond Business

This guide walks you through the essential steps on how to start a diamond business in India.

What to Consider Before Entering the Diamond Industry?

Before you dive into the diamond trading business, arm yourself with fundamental knowledge. This foundation is critical for making informed decisions and building a trustworthy brand.

1. Master the 4Cs

The "4Cs" are the universal language for evaluating a diamond's quality and value. Mastering them is non-negotiable for anyone in the diamond business in India:

  • Cut: This refers to how well a diamond's facets interact with light. It's the most crucial factor for a diamond's sparkle. A well-cut diamond reflects light brilliantly, creating fire (flashes of color) and scintillation (sparkle). An excellent cut can make a diamond appear larger and more vibrant than its actual weight.
  • Color: Diamonds are graded on a color scale from D (colorless, the most valuable) to Z (light yellow or brown). The less color a white diamond has, the higher its value. "Fancy colored diamonds" (like blue, pink, or red) are graded differently and are highly prized for their intense hues.
  • Clarity: This measures the presence of inclusions and blemishes. Most diamonds have some natural characteristics, but those with fewer and smaller imperfections receive higher clarity grades, as they are rarer and allow more light to pass through.
  • Carat: This is simply the diamond's weight. One carat equals 200 milligrams. While a higher carat weight generally means a larger diamond and higher price, a diamond's overall beauty and value are determined by the interplay of all 4Cs, not just its weight.

2. Study Diamond Certifications

Diamond certifications are vital. They provide an unbiased, expert evaluation of a diamond's 4Cs and other characteristics, issued by independent gemological laboratories. These certificates assure authenticity and quality, building trust with your customers.

Reputable laboratories like the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) are highly respected worldwide. Always prioritize certified diamonds to ensure you are selling genuine and accurately graded stones.

Step-by-Step Guide to Start a Diamond Business

Starting a diamond import/export business involves international trade laws and specialized procedures. This is a complex but potentially very profitable aspect of the diamond business in India.

Step 1: Register Your Business and Obtain IEC: As mentioned, formal business registration and an Import Export Code (IEC) from DGFT are fundamental.

Step 2: Register with Customs (Importer of Record): You must register with Customs and Border Protection (CBP) as an importer of record. This involves submitting specific documentation to establish your legal standing for importing goods.

Step 3: Obtain a Customs Bond: For imports valued at or above Rs. 2 Lakhs, securing a customs bond is mandatory. This bond guarantees that all duties, taxes, and fees owed to customs will be paid.

Step 4: Kimberley Process Certification (for Rough Diamonds): This is paramount for rough diamonds. You must obtain a Kimberley Process (KP) certificate for both import and export shipments. Rough diamonds must be transported in tamper-resistant containers. Upon import, notify the relevant port authority of receipt within 15 days. For exports, file your Electronic Export Information (EEI) through ACE/AES.

Step 5: Sourcing and Market Research: Identify target countries for sourcing (e.g., Russia, Botswana for rough; Belgium, Israel for polished trading) and target markets for export.

Step 6: Understand Harmonized Tariff Schedule (HTS) Codes: Use the correct HTS codes for all diamond imports and exports. Loose diamonds are typically duty-free, but set diamonds will have applicable duty rates. Incorrect codes can lead to delays or seizures.

Step 7: Compliance with International Regulations: Stay updated on all international trade agreements, sanctions, and specific regulations (e.g., recent restrictions on Russian-origin diamonds). As of March 1, 2024, diamond imports must include a self-certification of non-Russian origin.

Step 8: Logistics and Insurance: For high-value diamond handling, use secure logistics providers and equip your facility with vaults, surveillance, and access control.

Step 9: Inventory Tools & Digital Platforms: Implement robust inventory management systems like RapNet or IDEX to streamline stock tracking, pricing updates, and market listings. These platforms offer real-time access to global market data, allowing for better pricing decisions, buyer-seller networking, and instant visibility of stock availability. Efficient digital inventory tools reduce errors, save time, and improve overall operational transparency.

Step 10: Certified Grading Laboratories: Ensure every diamond in your inventory is certified by reputable gemological laboratories such as the Gemological Institute of America (GIA), International Gemological Institute (IGI), or Hoge Raad Diamant (HRD).

These institutions provide standardized grading for cut, clarity, color, and carat, building trust with buyers and supporting higher resale value. Certification enhances transparency, reduces disputes, and strengthens your credibility in both B2B and B2C transactions.

Step 11: Insurance for Shipments and Stock: Secure comprehensive insurance coverage for both in-transit shipments and in-house inventory. Partner with insurers specializing in high-value goods to cover theft, damage, loss, and natural disasters.

This includes insuring diamonds stored in vaults as well as those being transported by vetted, secure logistics providers. Proper coverage not only safeguards your financial investment but also reassures clients of your professionalism and risk management standards.

Sourcing and Managing Your Diamond Inventory

Effective sourcing and meticulous inventory management are critical for any diamond business in India.

1. Finding Suppliers and Manufacturers

  • Major Hubs: India's diamond industry is largely centered in Surat (Gujarat) for cutting and polishing, and Mumbai (Maharashtra) for trading and jewelry manufacturing. These cities are prime locations to find suppliers and manufacturers.
  • Trade Fairs and Exhibitions: Attend national and international gems and jewelry shows (e.g., IIJS Premier, Jaipur Jewellery Show). These events are excellent for networking and finding reputable suppliers.

Trade Fairs and Exhibitions of Diamond

  • B2B Platforms: Utilize online B2B platforms specifically designed for diamond trading (e.g., RapNet, Polygon).
  • Direct from Miners/Sightholders: For larger operations, sourcing directly from mining companies or their authorized distributors (sightholders) can offer better pricing but requires substantial capital and industry connections.

2. Quality Control

Applying strict quality control measures throughout your supply chain is non-negotiable to maintain your reputation and customer trust.

  • Gemological Expertise: Employ or consult with certified gemologists to thoroughly inspect diamonds for authenticity, 4Cs, and any treatments.
  • Third-Party Verification: Rely on trusted gemological laboratories for diamond certification.
  • Standardized Procedures: Establish clear protocols for receiving, inspecting, grading, and storing diamonds.
  • Technology: Utilize advanced equipment like microscopes, spectrophotometers, and specialized software for accurate grading and inventory tracking.
