Its elongated pear outline can work as a dramatic center stone, pendant focal point or asymmetrical custom-jewelry element. Jet black is a merchant visual description, not a laboratory color grade.\u003c\/p\u003e\u003ch2\u003eClarity \u0026amp; Setting\u003c\/h2\u003e\u003cp\u003eThis diamond is opaque, so internal clarity cannot be assessed in the same way as a transparent diamond. A qualified jeweler should review the pointed tip and facet edges when planning a setting. Tell the jeweler that the color is enhanced before setting, cleaning, resizing or repair. Because the enhancement method is undocumented, no claim is made that the treatment is permanent; the jeweler should select methods appropriate for an unidentified color treatment.\u003c\/p\u003e\u003ch2\u003ePhotos \u0026amp; Videos\u003c\/h2\u003e\u003cp\u003eAll 10 photographs show this exact diamond. Its black appearance and reflected highlights can vary with lighting, viewing angle, surroundings and display settings. No specific photographic lighting method is claimed.\u003c\/p\u003e\u003ch2\u003eReport, Treatment \u0026amp; Origin\u003c\/h2\u003e\u003cp\u003eThe diamond is color enhanced; the specific enhancement method and permanence are not documented in our records. Its identification as natural diamond, jet-black color description, opaque appearance and treatment disclosure are merchant assessments, not independent laboratory determinations. It was faceted at our diamond-cutting facility in Surat, India; this is the manufacturing and customs origin, not a mining-origin statement. Its mining origin has not been established.\u003c\/p\u003e\u003cp\u003eNo independent laboratory report is included. Identification as Natural diamond, together with the color, clarity and treatment statements, is a qualified merchant assessment based on our records and examination, not a laboratory determination. An IGI report, or a report from another agreed local gemological laboratory, may be arranged before dispatch subject to service availability. Contact us before ordering to confirm the available laboratory, testing scope, current cost and turnaround time; this service will extend the dispatch time, and the laboratory may reach a different conclusion.\u003c\/p\u003e\u003ch2\u003eAbout Brahma Diam\u003c\/h2\u003e\u003cp\u003eBrahma Diam works directly with loose diamonds and gemstones through gemstone cutting operations in Bangkok and diamond cutting operations in Surat.
