About US 



Omega Gem World is a co-operative venture between a UK based Sales and Marketing effort and a Tanzanian based mining and stone sourcing effort.

 Both organizations have extensive experience in gems, gem rough, and gem cutting. We can supply you with stones, cut or uncut, that are outstanding in terms of selection, color, and pricing.

 We are here to serve you by supplying select stones and parcels that previously have not been available to the general gem buying public.

Our Main Business being Tanzanite we also buy and sell almost every other stone found here and make the most of our Strategic location.


 All of our stones are sold with a satisfaction guarantee..... you can return any stone, if the stone or stones were not as described, with 10 days to get a full refund on your purchase price except for shipping and handling costs.

 We do not collect, store, or even see your credit card information. We use a US based credit card processor to ensure your safety.


WHY, do you ask is our prices so low? Because we sit at Source in Arusha, Tanzania and Nairobi, Kenya picking up all top material we can get our hands on. 


We operate on very small profits.

If you would like to be informed of new stones before we upload them to the website then please let us know on info@omegagemworld.com and we will put you on our email list for Special Deals.



Please contact us on info@omegagemworld.com for wholesale pricing or any enquiry for that matter.
