Refer to natural jadeite which is not subjected to any form of chemical treatment except processes such as colorless wax polishing are not defined as “treatment” on the crystalline structure of the jadeite jade, which has not been damaged.
Refer to jadeite jade which is chemically treated and resin impregnated to enhance its translucency. The structure of jadeite is damaged through this treatment and it will lose its lustre once the polymer deteriorates with the lapse of time. In addition, “B” jade cannot withstand heat and pressure.
Jadeite of this kind is usually colorless or of very faint tone, and is therefore dyed to enhance its brightness. However, such artificial hue will fade in time.

Yes, here at MGL, we provide multiple forms of authentication from verbal consultation (synthetic/natural/imitation) to full certification, including country of origin for any specific gemstone either loose or in jewelry.

No, MGL only provide authentication from verbal consultation (synthetic/natural/imitation) to full certification, including country of origin for any specific gemstone either loose or in jewelry.
Here at MGL, we strive to complete our tasks at an efficient rate without compromising on quality of work. For single gemstone projects, a customer may be able to get his or her gemstone back with full certification on the same day, but we recommend calling or emailing in beforehand to set an appointment as on average, it takes the MGL gemology team up to 3 working days per customer project (depending on number or gemstones / jewelry volume) to complete due to the amount of customers we have.
The simple answer would be no. This is because MGL do not require any destructive methods to gain the information we need for certification. For the most part, we do not even remove the gemstones from jewelry sent to us unless absolutely necessary. In the case that we need to remove the gemstone from jewelry, the owner will be notified beforehand and we would require confirmation before moving forward.
The lab that our gemologist team operates here at MGL is under CCTV surveillance at all times. Furthermore, upon agreeing to our services, the owner will be presented with a receipt stating the type of product received.
We examine and determine the authenticity of the stones including coloured stones, pearl, diamond and jade.

MGL is the first Gemological Laboratory at West Jakarta. Founded in 2015, we specializes in Gemstone evaluation, grading procedures and setting certification standards for the identification of authentic Gemstones around the world.
