III. About the Synthetic Ruby Identifier by

Presidium

The Presidium Synthetic Ruby Identier (“SRI”) is a revolutionary

new device developed to help identify amongst rubies, the synthetic

ruby that is created through the ame fusion method. Researched

and developed by Presidium in collaboration with the renowned Gem

and Jewelry Institute of Thailand (GIT) near the traditional source

hub of rubies, the Synthetic Ruby Identier is a breakthrough in the

development of gemological instruments, as it is the world’s rst and

only tool, aside from expensive laboratory equipment, that identies

certain common synthetic rubies.

The Synthetic Ruby Identier is designed as a test on known ruby

stones and to differentiate the synthetic ame fusion rubies from

natural and other forms of synthetic ruby. One way to ascertain if

the gemstone is a ruby is to measure the thermal conductivity of the

gemstone. If the gemstone is a ruby, the Synthetic Ruby Identier can

be used to further check if it is a synthetic ame fusion ruby.

Using the knowledge that when gemstones are subjected to deep

UV irradiation, the difference in their light transmittance is signicant

enough to aid in differentiating known rubies, the Synthetic Ruby

Identier measures the UV light transmittance ability of ruby stones,

as research1 has found that synthetic ame fusion rubies are

consistently more transparent to deep UV light.

1 Sim, Hwa San; Leelawatanasuk, Thanong & Saengbuangamlam, Saengthip. “Handheld

Synthetic Ruby Screener based on UV-VIS Light Absorption” in GIT 2012 (Bangkok; Gem

& Jewelry Institute of Thailand, 2012), pp199-204.

The Synthetic Ruby Identier features a deep-wave UV light that is

activated to pass through the ruby towards the photo-detector on the

base platform. Bars of coloured light on the front of the lid will provide

an easy reading that indicates if the UV light transmittance ability of

the tested ruby is high or low. Usually, a natural ruby will have a low

UV transmittance due to the trace elements within that absorb the

deep UV light. Other types of synthetic rubies such as those created

through the ux and hydrothermal methods could either have high or

low UV transmittance ability, depending on the presence of transition

metal ions introduced during the growth process and hence the device

cannot accurately identify those synthetic rubies. A synthetic ame

fusion ruby which is the most common type of synthetic ruby though,

will usually have few transition metal ions (mainly Chromium,Cr)

due to relatively ‘pure’ melt growth process, resulting in high UV

transmittance.

Created with the user in mind, the Synthetic Ruby Identier is

engineered to allow for very quick screening of single mounted ruby

stones (with open-back setting) and loose rubies to check if they are

synthetic ame fusion rubies. It is designed as a lightweight, portable,

sturdy and non-slip unit and it can be powered by 4 AAA batteries or

through its USB port connecting to an external power source.

The Synthetic Ruby Identier has been subjected to thorough and

extensive laboratory testing in collaboration with the Gem & Jewelry

Institute of Thailand (GIT), and will generally give clear and reliable

reading of the ruby being tested. This device only helps to identify a

certain type of synthetic ruby and to ascertain if your tested ruby is

natural or other forms of synthetic ruby, you are advised to conduct

further supporting tests.

The device was designed with the following objectives:

• Help to further quickly identify one type of common synthetic,

the synthetic ame fusion ruby from amongst known rubies

• Aid to further enable identifying natural ruby by screening out one

type of synthetic ruby

• Provide consistent and reliable test results under proper use and

understanding of its functions

• Feature user-safe materials and user-friendly ergonomics that gives

clear visibility of results, maximum sturdiness and grip, ease of use

and portability

• Help to identify most synthetic ame fusion rubies

• Tests on rubies within a range in dimension from 3 mm in width and

up to 6mm in height (approx. 0.1 to 6 carat size)

• Tests on polished rubies of common shapes such as round-cut,

oval-cut, princess cut, brilliant round cut, emerald cut, baguette cut,

square brilliant cut, step cut and mixed cut

• Can be used on both loose stones and rubies mounted on jewelry

with open-back setting

• Complete testing almost instantaneously

on the following as it may affect the accuracy of the readings:

× Unknown stones (users should only test on known rubies)

× Rough, unpolished stones

× Stones that are more than 6mm in height as the specic UV

wavelength has limited ray reach

× Opaque or translucent stones, and stones of dark red shades

× Testing if the stone has been subjected to treatments such as heat

irradiation and glass-lling

× Testing to identify other forms of synthetically created rubies such

as synthetic hydrothermal or synthetic ux stones

× Mounted stones more than 6mm in height on ring jewelry with

inside diameter measuring larger than 14.88mm (Italy ring size 6)
