Black obsidian rough stones from H S R ENTERPRISES are unworked natural volcanic glass pieces shaped by conchoidal fracture, not by cutting or tumbling. Individual specimens range from 20 mm to 80 mm in longest dimension, with highly irregular morphology reflecting their formation through rapid cooling of felsic lava. The colour is intensely black with occasional silver-grey metallic lustre on fresh fracture surfaces. These pieces retain all natural features including flow banding, inclusions, and percussion marks from geological extraction. Weight per piece varies from 30 g to over 200 g depending on size selection.
The material composition is amorphous silica (SiO2) with 70 to 75 percent typical content, plus aluminium oxide, sodium oxide, and trace iron and magnesium oxides that contribute to colour. Unlike crystalline quartz, obsidian lacks long-range atomic order, giving it a conchoidal fracture pattern and characteristic sharp edges when struck. Mohs hardness is 5 to 5.5. Specific gravity ranges from 2.40 to 2.60. The Jaipur source region processes rough material from volcanic deposits, though H S R ENTERPRISES does not specify exact mine provenance in their listing. Standard rough stone grading applies: pieces are sorted by size fraction rather than by clarity or colour uniformity criteria used for faceted gemstones.
These rough stones serve jewellery makers seeking free-form cabochon and wire-wrap material, Reiki practitioners who value unprocessed natural form, and aquarium or terrarium designers using black stones for contrast. Bulk purchasers include crystal shops, metaphysical wholesalers, and landscape architects specifying dark decorative stone. Because the pieces are unpolished, buyers should confirm with H S R ENTERPRISES whether size fractions are mechanically screened or hand-selected, as this affects uniformity. Packaging is typically bulk polypropylene bags or hessian sacks; individual piece wrapping is unusual for this product grade. Import classification falls under worked or unworked minerals depending on degree of processing, a detail to clarify with the supplier for accurate customs documentation.

H S R ENTERPRISES is based in Jaipur, Rajasthan, operating within one of India's principal hubs for gemstone rough and finished goods. The supplier lists an imported tier with voyage trust status on the platform. Response metrics show zero percent response rate with no recorded average response hours, suggesting limited platform-based communication activity. The listing positions the company as manufacturer, wholesaler, and exporter of rough gemstone material and crystal products. No additional profile details, facility descriptions, or third-party verifications are provided in the source data.
The supplier profile does not indicate year of establishment, number of employees, production capacity, factory ownership, or export volume. No certifications, memberships, or client references appear in the available information. Buyers are advised to conduct independent due diligence, including requesting business registration documents and any export licences required for rough mineral trade from India. The Rajasthan location provides access to skilled lapidary labour and established logistics networks, but this does not substitute for direct supplier verification.

Before importing rough obsidian from H S R ENTERPRISES, verify the supplier's ability to provide consistent size fractions and confirm whether photographic samples represent actual inventory or generic stock. Request that they disclose any treatments, including oiling, heating, or chemical enhancement, as these affect both value and suitability for sensitive applications such as aquariums or body-contact crafts. Establish whether the supplier carries product liability coverage, as sharp natural edges on unworked obsidian present injury risk that may affect your downstream liability exposure. Check that their export documentation includes accurate material description to prevent customs holds based on vague commodity classification.
Freight terms from Jaipur should be clarified explicitly: whether the supplier delivers to a nominated freight forwarder in Jaipur, or to an air/sea port such as Mumbai or Delhi. Rough stone is dense and heavy; ocean freight in FCL containers reduces cost for bulk orders but requires adequate packaging to prevent dust contamination of other cargo. Air freight suits smaller, urgent orders. Typical payment structures for rough gemstone from India involve advance payment against proforma invoice, with balance payment against bill of lading or airway bill. For first orders, consider using an escrow service or documentary credit to mitigate non-delivery risk. Confirm with H S R ENTERPRISES their banking details and whether they accept payment in USD, EUR, or INR to avoid exchange complications.
Upon receipt, inspect the shipment for moisture damage, as hessian sacks provide limited protection against monsoon humidity during Indian summer storage. Spread representative samples on white paper to check for colour uniformity and absence of mould. Weigh several pieces to verify density consistency with natural obsidian rather than lower-density substitutes. For resale, wash pieces in clean water and dry thoroughly before photography, as dust masks surface lustre. Retain all shipping documents and any supplier correspondence for warranty claims or customs audit. If stones are intended for therapeutic or metaphysical resale markets, consider independent laboratory verification of material authenticity, as consumer protection standards in this segment increasingly require substantiation of natural origin claims.
