[QUOTE="user 4386, post: 564433, member: 4386"] If you are new to this, do a search on "Series on identifying minerals" under my name. I have given extensive details on how to identify minerals by their properties (not all of these need to be done, but often one or two properties are quite diagnostic of a particular mineral - eg some scratch like soft cheese with a pocket-knife, others can scratch quartz, the combination of colour and streak can help (eg chalcopyrite is yellow but the powder is greeny-black). And few people bother with specific gravity but it is easily determined with a $20 electronic balance and is often highly diagnostic. You need one accurate to 0.01g not 0.1 g, and that will take a specimen of 200g mass if necessary: [url]https://www.ebay.com.au/itm/100g-0-01g-200g-0-01g-Precision-Digital-Pocket-Jewelry-Scale-Electronic-Balances/203042742436?hash=item2f464a60a4:g:NSgAAOSwiiVbuESp&frcectupt=true[/url] And good, in-focus photos like yours help others to help you. This can be done on a mobile phone using something like this (I bought the same for only $6 - it includes UV light which gives you an added property for some minerals).
