The history of Sugilite is now long and varied as to the laboratory analysis of the mineral itself and analysis of the many amalgamated "rocks" identified as Sugilite, with Sugilite existing in these "rocks", as only one mineral of the mix of other minerals, making up the total composition of the "rock specimen" being examined.

The assortment of "rocks" sold or provided as sugilite is vast, all basically sharing a "percentage" of sugilite rather than representing a sample of "pure" specimen of Sugilite. Then there is the so-called "Gel" sugilite, which in fact does exists but it requires more than the simple characteristic of "translucency".

The label "Gel", in marketplace use, is many times a misnomer, a quick marketing label, referring to the translucency of the particular sugilite "rock" you are looking at, not necessarily the level (percentage) of Sugilite or the "singular" purity level of Sugilite contained in any one specimen.

The term "gel" should be taken for how it is used by the seller's/provider's definition of their Sugilite rather than an actual scientifically based identifier of top grade, highest percentage "purity" sample of the mineral Sugilite.

As a participant in the laboratory analysis of sugilite in 1981 with the Gemological Institute of America and inspection of many multiple tonnage lots of rough sugilite (the largest single lot - 3 metric tons) over the years. It has been my personal "hands-on" experience to discover and calculate over 40 major mixed mineral "incarnations" of marketplace Sugilite rough, with varying percentages of the mineral Sugilite combined with other known minerals.

For the Wikipedia article, I would imagine providing information and photos of accredited, laboratory certified, "closest" facts as to the various forms and amalgamations of any one sample of Sugilite Ore, would be of public interest and importance to the general information guidelines of Wikipedia articles.

For more knowledge and direct information on Sugilite, here is the link to the Gemological Institute of America's past examination, findings and report on the mineral Sugilite.
