Blue Zircon

Chemical Formula ZrSiO4

Blue zircon comes from the zircon family. Blue Zircon naturally occur in nature and is often heat treated (thermal enhancement) to improve its colour. Blue zircon Main sources of Blue zircon are Cambodia, Brazil, Myanmar, Sri Lanka, Nigeria, Tanzania & France.

We can cut blue zircon in calibrated sizes in several shapes such as rounds, ovals, etc in various sizes. For more information on the sizes we usually keep in calibrated sizes, please click here.

We can also cut precision cut blue zircons, this is finely cut and crafted to bring the maximum brilliancy into it. This is done with the help of automated machines and skilled labour. For your demands in precision cut, please contact us for more information.

We can accomodate pairs, layouts and single unique blue zircons. Also perfected is the art of special cuts or custom cuts. This is suited to fit your specifications and can be any shape and/or cut of your choice. For your requirements, please contact us.
