Good evening,my name is Adamu,I work in Lagos and sometime ago,I went to my village In the north of the country and they were mining gemstones,I bought some as samples from the miners and contacted some gem dealers in Ibadan and send them pictures and they told me it’s low quality tourmaline and virtually worth nothing but they keep pushing me to tell them the location I got the stones from,I developed some doubts and I sent it the gemological institute of Nigeria in abuja for identification and the results came back as green garnet tsavorite and almandine garnet red.I did some research online and I see that they might be worth something …I just joined as a gemstone enthusiast who wants to become a gem miner and dealer.I went back recently and I also got more gemstone,one is orange and fiery red when under light and the other one is almost black but dark reddish under lights.Can someone kindly tell me what type of gemstone they might be and if it’s worth something.thank you
Good morning sir, I can concur that most of these are defiantly garnets, however when it comes to the green gems they would need further testing unfortunately. I will be honest and say that I am seeing more peridot or African green apatite. It is very difficult to tell from a picture and without assessing the gem in person it is much easier to identify from internal inclusions. The colour also is intriguing for garnet not unseen from African green garnets but deferentially a little off from the normal colours seen from day to day in Damantoid and Tsavorite, but so saying as I have said it is difficult to determine from a picture so it is still speculative untill tested.
Best regards Jarryed
Sorry!!! I forgot to say that what you have down as suspected spinel is actually carnelian, Pleas make use of its is amazing gem encyclopaedia and read up a little on it and then let me know how it goes and if you are able to conclude my suspicion of this by using the the identification guid for carnelian.
Good Morning Sir and thank you so much for taking your time to answer my question,I’m new and I just joined and I have many doubts regarding the stones as well ,I will take my time to learn more about carnelians and the only testing facility we have here in Nigeria which I know is the gemological institute of Nigeria and what they do is only identification.
No one can tell you what a gem is by looking at a photo, so don’t believe anyone telling you what your stones are without a gemological exam. Yes, the red stones do look like garnet. Much garnet, particularly in small sizes is very common and not worth much. Stones which show color on a piece of white paper (the “white paper test”) and which are various shades of pink, bright red, orange or violet can be worth fairly good money. Tsavorite in a real green grass shade that is over two carats and free of inclusions can be worth a lot of money, particularly if clean and in large sizes. What you show in your photo, assuming it really is tsavorite, is not prime color and does not look clean or clear.
Remember that you will need a lot of gem knowledge to do business and that people selling to you are likely to know a lot more than you do about it, so you are easy prey. Yes, there are some miners who know next to nothing, but even a lot of them will have picked up some knowledge. Either that or they think that every rock they find is worth hundreds and that you are trying to swindle them.
There is a wealth of info on line about gems…there are even free gemology courses. I haven’t had much luck instructing Africans in the finer points of gemology. They all seem to want to strike it rich immediately and that is just not going to happen. PM me if you want further pointers. Good luck! -royjohn
Thank you so much Sir for your Vivid opinion…Im grateful.
Everything you said is on point.I have so many doubts and that’s one of the very reasons why I joined IGS,I think I have learnt a lot in the past few days than I have done in months and I intend to learn as much as I can while I’m here.
Hi all. I’m also new on the platform and have had a similar experience with my land in Northern Nigeria. I got the place for farming but discovered some stones. I obviously need to learn as much as possible about them. I’m also open to any advice I can get. Thanks.
