Top 5 Presidium Products in 2021

As a professional jeweler or serious jewelry collector, your primary goal is to ensure the authenticity of the pieces you buy and sell. Because in this industry, trust is the most important currency. This is why knowing the true value of the jewelry or gemstones that pass through your hands is a must. As such, you need the most updated tools and access to reputable providers of gemological instruments. But with so many choices, what brand or company can you count on? And how can you be sure that the instruments or technology they offer are not outdated?

Reason dictates that the industry pioneers would have the most experience and expertise, and one such industry forerunner is Presidium Instruments Pte Ltd (est. 1979) — the world’s first brand to launch groundbreaking gemological instruments. Catering specially to the jewelry industry, Presidium products are available across more than 40 countries.

The company’s customer base includes gemological institutes, laboratories, jewelry manufacturers, diamond appraisal businesses, and retail jewelers. But even if you are just starting up with your jewelry business or precious stone collection, you can benefit from the reliable products that this company offers. Additionally, Presidium ensures secure transactions, fast delivery, and products that are always in stock. So, read on and check out the best of what they have to offer this year.

1. ARI by Presidium

ARI by Presidium®

The ARI by Presidium is a handheld diamond and moissanite screener that distinguishes colorless diamonds from CVD/HPHT lab-grown diamonds or moissanites—for loose and mounted stones. There’s a reason why “Presidium Diamond Verification Instrument” is a registered trademark. It’s because Presidium is the world’s first company to launch numerous gemological instruments, which says volumes about the ARI handheld diamond tester. [TAP HERE TO VIEW THE VIDEO TUTORIAL

The ARI can verify all types of moissanite, including the new “low conductivity” moissanite and stones as small as 0.02ct. It can test polished, loose, or mounted stones with all types of settings, including closed-back settings. Moreover, the ARI works well with the Presidium Diamond Mate Tester (PDMT-A) by measuring the stones’ UV light absorbance ability. This means users can easily identify natural diamonds, lab-grown diamonds, moissanite, and diamond simulants in just three seconds.

Product Benefits:

  • User-safe UV Retractable Optical Probe activates only when the tip is in contact with the diamond
  • Alert buzzer for loss of contact between optical probe tip and diamond during testing
  • A six-language selection in the Graphic User Interface (GUI)
  • Battery operated with stylish ergonomic design for portability and ease of use
  • Tests colorless diamonds and moissanites from D to J color
  • Designed for both left- and right-handed users 
  • Replaceable Optical Probe Tip, which means no need to buy a new unit in case of wear and tear

2. Presidium Diamond Mate Tester (PDMT-A/PDMT-C)

Presidium®  Diamond Mate Tester

The Presidium Diamond Mate Tester (PDMT) boasts of the thinnest probe tip size, which is 0.6mm. It is the industry’s tiniest probe tip to date, which means the PDMT can be used on diamonds as small as 0.02ct. Test results are instantly indicated by an LED light and a continuous audible beep. This handy pocket-sized instrument comes in 2 versions: (1) powered by 3 AAA alkaline batteries (PDMT-A) or (2) by an inset rechargeable battery (PDMT-C).

The Diamond Mate – A (PDMT-A) is a complementary product to ARI by Presidium, which allows users to further distinguish diamond simulants such as colorless sapphire and cubic zirconia from unknown colorless stones. As a first step, users can test an unknown colorless stone using the PDMT-A. Upon a positive “Diamond” reading, users can then use ARI to test if the stone is a natural diamond, potential lab-grown CVD/HPHT diamond, or moissanite. [TAP HERE FOR VIDEO TO KNOW MORE]

Product Benefits:

  • Retractable thermoelectric probe tip for enhanced accuracy

3. Presidium Gem Tester II (PGT II)

Presidium® Gem Tester II

The Presidium Gem Tester II (PGT II) determines and measures precisely the thermal properties of 16 types of colored gemstone. Touted as the industry’s most trusted gem tester, the PGT II has been redesigned for enhanced user convenience and ease of use. As such, the new-generation Presidium Gem Tester II is now even more compact, sturdy, and portable. Additionally, it has a clear display and easy-to-read analog dial, plus built-in glass and calibration (CAL) test discs for reference.

The PGT II can quickly identify diamonds or moissanites, as well as up to 16 common types of colored gemstones, based on their thermal conductivity. However, it does not differentiate between natural and synthetic colored gemstones, or diamonds against moissanites. The unit features the industry’s thinnest probe tip size of 0.6mm. Moreover, the PGT II tests gemstones as small as 0.02ct, and even works on coated gemstones.

Product Benefits:

  • Retractable thermoelectric probe tip ensures constant pressure between probe and gemstone
  • Metal alert buzzer to ensure probe tip is in contact with gemstone during testing
  • Tests both polished and unpolished gemstones
  • Consistent and reliable results every time
  • No waiting time between tests
  • Runs on 2 AA batteries or adaptor (included)

4. Presidium Electronic Gemstone Gauge (PEGG)

Presidium® Electronic Gemstone Gauge

The Presidium Electronic Gemstone Gauge (PEGG) is the industry’s first digital gemstone gauge. It is a portable carat converter that can differentiate laboratory-grown Type IIa colorless diamonds from natural Type Ia colorless diamonds, with accurate results. The PEGG is recognized globally as the most reliable digital gauge for measuring gemstone dimensions. The unit also comes with the Presidium Gemstone Weight Estimation Table for converting millimeters to carat weight in brilliant-cut diamonds. [TAP HERE TO VIEW THE VIDEO TUTORIAL]

The PEGG utilizes solid-state electronics to accurately measure up to 1/100mm stones. It has a patented anvil with a non-metallic, lubrication-free rack and pinion—making it highly resistant to wear and tear. As such, users are assured that the PEGG maintains its precision and accuracy for many years. Additionally, it features a clear digital display and convenient touch button for resetting/calibration.
