WORLDS LARGEST GEM STORE
Most gemstones on the market today have been modified by mankind in one way or another. Some gemstones such as Peridot, Csarite® and Garnet are not enhanced at all (other than the cutting and polishing) but there are many gems such as Tanzanite, Emerald, Sapphire, Ruby and Topaz that are normally enhanced.
As a lot of treatments are carried out whilst the gem is in the raw crystal stage, it’s even often impossible to be 100% sure what enhancements have been made to a particular gem. We can, however, provide information about the most common treatments that certain gemstones undergo.
Many of these enhancements have been practised for thousands of years. The dyeing of Agate is one example. Others, such as irradiated Blue Topaz, are solely a product of the technological advances of the modern age. Enhancements often have an impact on the value of precious stones, with the highest prices paid for natural gems of fine quality that have not been enhanced in any way beyond ordinary cutting and polishing.

To our Gemporia Family,
As we all navigate these challenging times together we wanted to let you know you we are making changes to protect our Gemporia partners, while we remain here for you.
For our community of passionate collectors, Gemporia is a source of comfort and joy and has been for many years. Together we’ve been entertained and inspired by the world of gemstones and jewellery and made many friends along the way. Your continued company has humbled us and reinforced for us how precious our community is. We will continue to do everything we can to treasure and honour our relationship with you, following 3 key principles:
Safety: The safety of our partners is paramount. We will be led by this first and foremost and so you may notice some parts of our service changing. For example, one measure we are exploring is how our help team partners can answer your calls from their home. You can help us with this by choosing to order more online. Together, we can help protect our team in line with the latest advice from HM government.
Security: As an employee-owned trust we don’t answer to external shareholders. Our team are the owners and their financial security, along with the security of the thousands of miners, lapidarists, etc. around the world who are all stake-holders in the global gemstone community is an on-going concern. We want to ensure that as safely as possible, we can make sure we are here for all of us for many years to come.
Social: In these times of social distancing we are fortunate that you continue to spend your valuable time with us. We are always with you and are making our live shows even more interactive, so you can join our conversation on screen, online or on our app.
We thank you for your continued to support and wish you and your loved ones the best of health as you stay safe.
