Abstract
On the faces of a type I diamond octahedron of particularly good quality there have been observed clusters of trigons which appear to be associated with a centre of strain in the interior of the stone. The trigon patterns show features which can only have been the result of surface dissolution. These observations are discussed, and it is concluded that most trigons are etch pits; there is evidence that these particular trigons are centred on dislocations. Possible explanations are considered for the fact that the usual laboratory etchants develop pits oppositely oriented to trigons.Keywords
