The specimens of the supposed gems recently discovered on Kangaroo Island, which were submitted to Mr. H. Spinks, the well-known lapidary, of 77 Flinders-lane, Melbourne, have been examined, and the following report has been received by the syndicate from Mr. Spinks :— " Melbourne, Jan. 18, 1897. "Gentlemen,—I received your letter of Saturday, 23rd ult., and the packet this morning, and beg to report on the stones contained therein. Five stones in parcel No. 1—One diamond and four topazes. Six stones in parcel No. 2 are garnets ; they are more like what are called Cape rubies than the stones from the McDonnell Ranges. Three stones in parcel No. 3 are crystal quartz. Doubtless, where these stones came from valuable stones must be found. I will cut best of stones and send over to you. This report bears out exactly the report made to the syndicate and your representative by Mr. F. C. Bowen, of this city."
Mr. F. C. Bowen informs us (says the Adelaide Register) that he had submitted to him last week by W. Shegog, of Kangaroo Island, a fine large topaz, found by him at Karratta, on a claim adjoining Messrs. Rosengarten and Borrow's properties. Among the passengers by the steamer James Comrie, which arrived at Port Adelaide recently, was Mr. M. Schroder, who has been in search of gems in Kangaroo Island. Mr. Schroder, in company with Mr. J. Turner, has been prospecting in the Stunsailboom and Harriet Rivers for a fortnight. They both returned from Kangaroo Island on Saturday week last, and gave very favourable reports, and thought that the localities were worth trying. Mr. Schroder brought with him a parcel of stones, which he will place before his syndicate at Adelaide.

[1903] In another column we publish an announcement that the prospectus of the Kangaroo Island Amalgamated Gem Syndicate, No Liability, will be issued today. Tourmalines have been found in various colours, and many beautiful gems have been obtained from the properties. Several parcels have been sold at satisfactory prices. Samples of the tourmaline have been, sent to Lon don, Paris, and Germany, and the latest advices indicate that there is a good market for the gems and that tourmaline jewellery is very fashionable. There is also a demand for the gems in Australia. In the development of the gemfields over £1,000 has been spent in proving the properties, with the result that there is every promise of a permanent industry being established in Kangaroo Island. A splendid collection of tourmalines, both cut and in the rough state, will be on view to-day at the office of the broker (Mr. W. A. Kingsborough).
Register (Adelaide, SA : 1901 - 1929), Friday 27 November 1903, page 7[1903] Mr. S. Cullingworth, who arrived in Adelaide on Tuesday from the Kangaroo Island gem field, brought with him some fine tourmalines. They are cylindrical and triangular in shape, and of a perfect pea-blue color, and are the first of the kind which have been found on the field. They came from the Aororangi lease. Mr. Cullingworth also brought from the same lease some large black rock crystals. One of these weighs about 50 lb., and is about 20 in. in length. Its formation is curious, as it has a smaller crystal growing in a lateral direction into one of its longitudinal surfaces. Mr. Cullingworth reports hopefully on the prospects of the field.
