Better on the safe side with SMARTPRO diamond testers

Read the article from the latest edition of the magazine “Juwelier Business”!

Diamonds that are artificially produced in a laboratory are on the rise. The differences from a natural stone cannot be detected with the naked eye or even a magnifying glass. So anyone selling watches and jewelry with diamonds should be sure whether they are dealing with natural stones or synthetic diamonds such as CVDs/HPHTs.

With the high-tech devices from SMARTPRO, ERNST & FRIENDS exclusively offers gemological testing equipment to distinguish between natural and man-made diamonds.

The portable SMARTPRO OPTIMUM (2855), for example, distinguishes between natural and synthetic diamonds as well as synthetic moissanites between 0.015 to 10 ct. – colorless to faint yellow (D-M).

The SMARTPRO AURA (2856) can analyze entire batches. It scans loose and set stones, identifies diamonds, CVDs and HPHTs, cubic zirconia (CZ) and synthetic moissanite incl. Forever One Stones, all colorless to faint yellow (D-K).

TIP: For the most reliable results, ERNST & FRIENDS recommends the 2-phase testing procedure.

Step 1: The popular SMARTPRO Multi Reader (2850) is used to distinguish diamonds from moissanites, simulants and cubic zirconia. The result “diamond” can be a natural or synthetic stone.

Step 2: Therefore, the SMARTPRO Optimum (2855) is then used to analyze whether the tested stone is a natural or synthetic diamond.

Both devices can be controlled with the intelligent SMARTPRO App – including a practical certificate to hand out to the customer. The application is very intuitive and simple. The result is given in seconds.

Our absolute bargain price for the combination set ( 2855.c):

Just 1195.00 EUR!

We offer exclusive novelties in the ERNST & FRIENDS portfolio! The manufacturer SMARTPRO, well known for its innovative gemstone testers, now brings new momentum to the engraving market with two brand new products. With the “AIR DO S” and the “AIR DO X” you get a compact all-in-one device for pneumatic engraving – at a fair price. In addition, the “AIR DO X” takes this to the next level with a built in 35,000 rpm micromotor.


Integrated into both devices is a whisper-quiet 40 bar compressor. In combination with its compact housing and a weight of just 5 KG, this makes the AIR DO a real game changer for your workshop. Users will be able to safe a lot of space. A large and noisy external compressor is no longer necessary.

However, the compact size does not mean that the unit sacrifices performance. That’s because with a precisely adjustable output of 400 to 8,000 strokes per minute, the unit covers everything from fine engraving up until stone setting in hard materials such as metal.

The included foot pedal for speed control makes your work even easier. Also included is a set of 6 easy-to-change engraving adapters. With a retail price of just 995€ (AIR DO S) and 1,195€ (AIR DO X), the devices make a real, reasonable alternative to the devices of established manufacturers.

One of them wrote to us: “Compared to competing products, the multifunctional tool convinces with its compact size and affordable entry-level price. (…) Anyone who enjoys beautiful tools and feels like expanding their product range can quickly achieve good results with this device.”

In over 60 countries worldwide, CONNOISSEURS care products are among the TOP items when it comes to caring for high-quality genuine jewelry. The clever Jewellery Wipes – a reclosable case of 25 special wipes for the waterless dry cleaning of gold and silver jewelry – have proven to be a particular best seller. Professional care that is quick and uncomplicated to realize.

Valuable pieces of gold and silver jewelry cannot be cleaned with standard household products. Particularly dangerous are supposed “tips” from the Internet, which advertise toothpaste as a home remedy for cleaning jewelry. But the toothpaste can contain ingredients that attack the jewelry and scratch it due to their too hard abrasive particles. Instead, you should use proven cleaning products whose formulas are specifically designed to clean gold and silver. This is the only way to ensure safe and effective care.

One manufacturer that has achieved a great deal of recognition and fame in this area is the American company CONNOISSEURS. The global market leader in genuine jewelry care covers all common materials and types of application with its extensive product range. Our recommendation for the uncomplicated care of gold and silver jewelry are the Jewellery Wipes, which, thanks to a sophisticated formula, sustainably remove patina and deposits of all kinds from jewelry and restore its old shine. Despite their high effectiveness, the wipes are completely non-toxic. They are packaged in a practical, resealable plastic case which, in combination with the stylish counter displays, is a real eye-catcher. A perfect addition to your assortment, which enables you to generate additional revenue and provides your customers with real added value.

Like all objects in our daily lives, jewelry must be cleaned regularly and, above all, properly. It can regain its old shine by being treated with a special polishing cloth. If the cloth is also printed with your own logo, it becomes an effective tool of customer loyalty for the jeweler.

The fine materials from which our jewelry is made are sensitive and suffer from the stresses of daily wear. Whether it’s grease, dust, sweat or body lotion, the jewelry gets dirty and no longer looks as beautiful as it did when it was brand new. Therefore, it must be cleaned regularly with the right material. And that can be bought at your local jeweler.

The main reason for the annoying loss of luminosity and shine of jewelry over time are the many micro-scratches that are practically unavoidable in everyday life. The jewelry then appears dull and matt. Micro scratches in jewelry can be easily polished out of the material with a jewelry polishing cloth. This way, your favorite pieces will shine again as on the first day and make their wearer happy.

ERNST & FRIENDS offers suitable solutions in this area. Both classic microfiber and special jewelry polishing cloths are provided in practical individual packaging. A special highlight are also the elegant microfiber gloves for handling especially high-value pieces. They signal appreciation and professionalism to the customer. He knows that he is with a professional jeweler.

Our service for you: for all mentioned products there is the possibility of individualization with your logo. This way you make your brand visible and strengthen the brand loyalty of your customers. The customer will transfer the positive characteristics of the care products to your name and you and your brand will be remembered. Simple, but effective.

The German company polyWatch has developed three high-performance premium products especially for the treatment of wristwatches. A product each for glass, plastic and protective sealing.

What could be more beautiful for watch lovers than the feeling of wearing a flawless, new watch on their wrist? You can’t resist looking at you new watch all the time. A view that makes you happy. At least until the first scratches and marks disturb the beauty of bracelet and case of the expensive timepiece. That’s annoying, but no disaster thanks to polyWatch.

In fact, wristwatches are predestined for scuffs and scratches of all kinds due to their exposed position on the outer wrist. Especially if the watch is a faithful companion in everyday life and is not only taken out of the cabinet on holidays. But how do you get scratched watches and scuffed bracelets back to their former glory? The three polyWatch products in detail:

polyWatch Plastic Polish

The elegant folding box contains a 5g tube of the high-tech polishing paste, a perfectly matched polishing cloth and a step-by-step manual.

The polishing paste is applied to the scratched plastic watch glass and the polishing cloth is used to remove the scratch from the scratched glass at a 90° angle.

polyWatch Glass Polish

Speaking of jewelry, polyWatch Glass Polish contains microscopic diamond grains that ensure professional results in the treatment of small and medium scratches in mineral and sapphire glass. The clever all-inclusive repair set also makes economic sense, because it preserves the value of the watch and is significantly cheaper than replacing the watch glass. And the set lives up to its name: a tube of repair paste, a tube of finish paste, a polishing rod, matching polishing strips made of fleece and a step-by-step manual leave nothing to be desired and ensure amazing results.

polyWatch Watch Protector

Prevent scratches in the watch glass in advance? Sounds almost too good to be true. But it is possible thanks to the polyWatch Watch Protector. The two-component system provides a protective film on the watch that protects against scratches, fingerprints and dirt. And that for up to 12 months. This is made possible by liquid glass technology with the futuristic name “Nano-Tech”. Everything needed for application is included in the elegant black sales packaging, which comes in a fashionable 6-counter display.

For jewelers, the products offer clear benefits:

– Because they are consumables, they increase frequency in your retail store.

– They are an easy way to realize additional revenue with good margins.

– They are perfect as bonus items or as a giveaway e.g. instead of a discount or for sales promotions.
