Frequently Asked Questions (FAQs)

How do I identify reputable Indian diamond manufacturers?
Start by checking company credentials, years in business, and memberships in institutions like the Gem & Jewellery Export Promotion Council (GJEPC). Read reviews, ask for client references, and verify certifications such as Kimberley Process compliance to ensure ethical sourcing.

What should I consider when choosing a diamond supplier in India?
Look at product quality, grading certifications (e.g., GIA, IGI), pricing transparency, customization options, and minimum order quantities. Good communication, reliable delivery times, and strong after-sales support are also important factors.

How can I verify the quality of diamonds from an Indian manufacturer?
Request detailed certificates from reputable gemological labs for any diamonds you plan to purchase. Ask for high-resolution images, videos, and samples. If possible, schedule a physical inspection or use a trusted third-party to assess the goods before finalizing your order.

Are there risks involved in buying directly from factories in India, and how can I minimize them?
Risks include quality inconsistencies, communication gaps, and potential fraud. To minimize risks, use secure payment methods, insist on formal contracts, and start with smaller orders to build trust. Visiting the factory or using trusted sourcing platforms also helps ensure legitimacy.

How do I find Indian diamond manufacturers who can tailor products to my needs?
Contact manufacturers directly and inquire about their customization capabilities. Many offer bespoke services like unique cuts, engravings, or jewelry designs. Provide clear specifications and ask for sample work to evaluate their ability to meet your requirements.
