Source-derived summary

The Black Diamond Apple (Tibetan: ནག་པོའི་གཟེར་ནོར་ཀུ་ཤུ་, Wylie: nag poʼi gdzar nor ku shu) (Chinese: gāla guǒ; 嘎啦果) is a rare variety from the family of Huaniu apples that is cultivated in the Tibetan region of Nyingchi. Despite what the name suggests, the apple is a purple hue with white pulp on the inside. Its unique color is due to the region's high altitude of over 3,500 m. The temperature fluctuates wildly between day and night, with the apples being exposed to a lot of ultraviolet light, which is conducive to the dark skin. Belonging to the high-end segment of the market, the average Black Diamond Apple is sold in high-end supermarkets and it costs about 50 yuan (7.75 USD). Many farmers are reluctant to grow the fruit, since Black Diamond apple trees can take up to eight years to reach maturity, and because the growing season is short (only about two months).

Editorial summary

This brief starts where responsible research should: with the source description of “Black Diamond Apple” as apple cultivar. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 152-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Black, Diamond and Apple can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as apple cultivar. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q85747510. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
