Ruby

Chemical Formula Al2O3

Ruby is from the corundum family. It is red because of the presence of the trace element chromium. Ruby naturally occur in nature and it is common to heat (thermal enhancement) them to improve their colour. The untreated ones are rare and command a premium. Rubies originate from various localities like Myanmar (Burma), Mozambique, Tanzania, Vietnam, India, etc.

We carry heated ruby in calibrated sizes in several shapes such as rounds, ovals, marquise, baguettes, 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 rubies, 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 rubies in both heated and unheated material. 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.
