is "Matryoshka" a specific diamond, or a synonym for "double diamond" ? edit

The bulk of the article is written as if Matryoshka is a specific diamond, rather than a class of diamond ("double diamond"). On that basis I have removed the picture of the Ellendale diamond (and moved it to Diamond#Double_diamonds), and edited the wording slightly.[1]

Given that the Russian diamond is the first - and until the recent (Oct 2021) discovery of the Ellendale diamond - apparently the only known instance, it's not immediately obvious whether "Matryoshka" covers all double diamonds. Mitch Ames (talk) 05:17, 27 November 2021 (UTC)Reply
