Which one of the following foreign travellers elaborately discussed about diamonds and diamond mines of India ?

Says Bernier's Travels are 'marked by detailed observations, critical insights and reflection', indicating he tended to describe economic and material aspects of Mughal India in depth.

A student could use this rule (Bernier records detailed material observations) and check whether his itinerary or chapters cover diamond-producing regions or trade topics to assess if he discussed diamonds elaborately.

Notes Bernier observed 'vast quantities of the world's precious metals flowed into India' and mentioned a prosperous merchant community engaged in long‑distance exchange.

Combine this with basic knowledge that precious stones were part of long‑distance trade to evaluate whether Bernier likely commented on gemstones (including diamonds) and trade/mine locations.

Bernier praised Indian workmanship in 'beautiful gold ornaments' and fine metalwork, showing attention to precious goods and their manufacture.

Given his interest in jewelry and luxury goods, a student could plausibly search his text for extended treatment of gemstones/diamond sources to see if he discusses mines or gems at length.

Gives publication and circulation details of Bernier's works (widely translated and reprinted), implying his accounts were comprehensive and accessible to contemporaries.

A student could use this to justify consulting the published editions/translations (mentioned here) to directly check for extended chapters or passages on diamonds/mines.

Mentions diamonds were exported from Pulicat, indicating active diamond trade centers in the region during the period, a subject a detailed traveller might report on.

Using knowledge of trade ports, a student could map Bernier's travel route against known diamond export centers to infer whether he had opportunity to observe/describe diamonds or mining activities.

This snippet shows that seventeenth-century French travellers (example: Jean-Baptiste Tavernier) wrote detailed accounts about trade in India, including repeated visits and focused interest in commerce.

A student could infer that other contemporary French travellers (e.g., Thevenot) might also record commercial matters such as gems, and so should check Thevenot’s travel writings for similar trade/diamond passages.

Tavernier’s quoted observation about moneychangers indicates that French travellers documented economic details and financial practices linked to valuable commodities.

Use the pattern that French travellers recorded economic life to justify looking in Thevenot’s accounts for mentions of diamond-related finance or markets.

This snippet identifies Surat as a major historical centre for diamond cutting and trade, a factual target a traveller interested in diamonds would likely describe.

A student could map Thevenot’s itinerary (if known) against major diamond centres like Surat to assess whether he had opportunity to discuss diamonds elaborately.

The Dutch exported diamonds from Pulicat, indicating that ports and European visitors were involved in diamond trade and thus commonly referenced gems in travel/merchant reports.

Check whether Thevenot visited or referred to ports known for diamond export (Pulicat, Surat); presence at such ports would make elaborate discussion more plausible.

This geographic snippet lists specific Indian diamond-producing regions (Bundelkhand, Andhra, Karnataka, Panna) which are the kinds of mining/locality details travellers might report.

Compare locations described by Thevenot (if his route mentions these regions) with known diamond districts to gauge whether he had material and occasion to write at length on mines.

This snippet notes that many travellers and missionaries wrote detailed travel accounts used as historical sources, implying such writers often treated economic and social topics in depth.

A student could check catalogues of travel accounts or missionary writings for Abbe Barthelemy Carre to see whether his works are of the same genre and scope.

Lists famous non‑British travellers whose published accounts are used as primary sources, showing that non‑British visitors commonly wrote descriptive accounts of India.

Use the pattern (non‑British travellers published descriptive works) to search bibliographies for Carre and inspect his subject matter for references to diamonds/mines.

Gives an example of a travel description (the Hampi bazaar) that explicitly mentions rubies, diamonds and other precious stones, showing travellers often described gem markets.

Compare this genre example to Carre's writings (if available) to see whether he similarly described gem markets or mineral wealth.

Provides concrete information about the geographic locations and mining/processing centres for diamonds in India, the kind of factual detail a traveller might discuss.

A student could check whether Carre mentions these well‑known districts (e.g., Panna, Bundelkhand, Surat) as a test for whether he discussed diamond geology/industry.

Shows that travellers' testimonies have been used to document commodity flows (e.g., silver), indicating travel accounts can include economic details relevant to mining and trade.

Apply this pattern by examining Carre's accounts for economic commentary or commodity circulation references related to diamonds.
