NOMENCLATURE

Our nomenclature complies with international accepted standard. In a quest for transparency and clarity we disclose any enhancement found at the time of examination.

 

A gemstone can be subject to multiple enhancements and are not limited to the one below 

Our enhancement detection is done with the excellency applied in all our task. Our laboratories are equipped with state-of-the-art equipment and complete reference collections of all enhancements coupled with professional gemologists.

Enhancement Disclosure

Ruby & Sapphire

-No Indication of Thermal Treatment-

No present alterations of internal features and gemological propriety (Such as infrared and photo-luminescence spectrum). 

-H-

Enhanced by heat only.

-H1- 

Comment: (Indications of Healed Fissures)

Enhanced by heat with insignificant amount of residues present.

-H2- 

Comment: (Indications of Healed Fissures)

Enhanced by heat with minor amount of residues present.

-H3- 

Comment: (Indications of Healed Fissures)

Enhanced by heat with standard amount of residues present.

Aggregate of corundum

-H(PHT)-

Comment: (Indications of Moderate pressure applied)

Enhanced through HPHT method (High Pressure High Temperature ).

-H Lead Glass (Pb)-

Enhanced through Glass filling method (Lead present in healed fissures).

-H-D(*)-

*Cr or *Ti or *Be or *Li

Enhanced by heat with diffusion of foreign material to enhance color.

-CE:Oil-

Clarity enhancement has been detected at the time of the examination

Emerald

-CE: None-

No clarity enhancement detected, and no apparent fissures for future enhancement present.

-CE: No Oil-

No Clarity enhancement detected, apparent fissures for potential future enhancement present.

-Quantification of present filler-

Quantification & identification is done trough FTIR and Raman spectroscopy, IR imaging, UV imaging and careful magnification.

Clarity enhancement detected at the time of examination, the following enhancement disclosure might appear depending on our quantification of the present filler:

-CE: Insignificant.

-CE: Minor.

-CE: Standard.

-CE: Significant

Clarity enhancement identified at the time of examination, the following enhancement disclosure might appear:

Enhanced by heat only.

-H-D(Co)-

Enhanced by heat with diffusion of foreign material to enhance color.

-CE:Oil-

Clarity enhancement has been detected at the time of the examination

Jadeite

-Natural Jade-

Natural Jadeite Jade including most common aggregate of the Pyroxene group containing Jadeite, Omphacite, and Kosmochlor. This group does not include Nephrite. 

-Type A-

Any Nephrite-Jade, and Jadeite Jade, that does not show indications of having undergone modification through the impregnation with colorless or near colorless wax, resin or any other agents.

-Type B-

Any Nephrite-Jade,and  Jadeite Jade, that shows indications of having undergone modification through bleaching and the impregnation with colorless or near colorless wax, resin or any other agents.

-Type C-

Any Nephrite-Jade,and  Jadeite Jade, that shows indications of having undergone modification through fissures filled with colored agents (Dyed)

Other Enhancement & Comment
