IDENTIFICATION OF TOPAZ
IN TIMES PAST, THE NAME OF TOPAZ
HAS BEEN applied, with different prefixes, to yellow stones of several entirely distinct species. Thus oriental topaz
denoted yellow corundum; occidental topaz
, Spanish topaz
, etc., were names for yellow quartz, while the prefix Brazilian
distinguished the gem-stone to which the name topaz can alone be rightfully applied to-day. For the persistent incorrect use of the term topaz (with or without some fancy prefix) for various shades of yellow or brownish-yellow quartz the influence of big dealers in the German stone-cutting centre of Idar-Oberstein was perhaps largely to blame. Their trade in gems of the quartz family was far and away greater than for other stones (including true topaz), and they clung obstinately to topaz
as a good selling name for quartz of topaz hue.
Importers in this and other countries, receiving parcels from Idar labelled topaz
would naturally sell the stones under this name—and so the misnomer persisted, and still persists. Some of the most heated discussions in the Precious Stone Committees at recent B.I.B.O.A. (International Jewellery Trades Bureau) conferences have centred round the misuse of this particular name, and various unsatisfactory compromises have been suggested.
The writer appeals to jewellers to abandon old customs and prejudices and to sell their goods under the correct names—that is, in the case under discussion, to use the names citrine and cairngorm or morion for the yellow or brown quartz, respectively, and to reserve the name topaz solely for the Brazilian
, true
, or precious
