Hardness Test 10 Pen
The deluxe hardness pick set is a tool for mineral identification, including a set of hardness pens for performing a 'scratch test' on an unknown mineral to determine its hardness under the mohs scale. This deluxe kit includes two other mineral identification tests. All 10 pens comes packaged in a beautiful mahogany-finished wooden case. This tool is a lifetime keeper, and makes an excellent gift!
Features:
This set includes 10 mohs' hardness stainless steel pens from mohs' 1 through mohs' 10.
Table of minerals sorted by mohs' Hardness.
All neatly packaged in a compact wooden case.
To perform a scratch test, select a numbered hardness pen, and try to scratch a flat, smooth surface
of the mineral. For example, if the number 6 pen scratches your mineral, but the number 5 pen does
not, then your mineral has a mohs' hardness value of about 5.5. This is an important mineral
identifying criteria.
This beautiful and thoroughly conceived tool is made for the opposite of "planned obsolescence".
This is a perfect tool for rockhounds, geologists, and archaeologists, as well as for schools as an
educational tool.
Hardness Test 5 Pen
This set have the same features like the item above, the difference is:
This set includes 5 mohs' hardness stainless steel pens from mohs' 5 through mohs' 9  packed in a plastic case.

Gemstone Refractometer
The gemolodical refractometer is considered by many to be the most important of all gem testing instruments. The primary use of the refractometer is to measure the angle at which light traveling through the stone is bent or refracted. This is called Refractive Index (R.I.). As Refractive Index is usually different for different gemstones, this provides an important clue for accurate gemstone identification. Gemological refractometer also can be used to determine whether or not a stone is single or double refracting. For doubly refracting stone, based on the difference between 2 readings you obtain from the refractometer, strength of the gemstone's double refraction (birefringence) may be computed and it offers an important gem identification aid, as it differs from gem to gem. Also refractometer is one of the few instruments capable to give you information for opaque stones as well as transparent stones. Quality of the instrument is important to enable you to perform consistent and reliable test for years to come. Our refractometer has all metal construction with built-in light (no flashlight or any other light source required) and polarizing filter, allowing you to perform all needed tests, it comes with vinyl soft case with belt loop for convenience while traveling and hard case for safe storage.
Features:
All metal quality construction Built-in LED light source with 3 x 1.5v batteries (not included)
Accuracy 0.01 Measurement range: 1.30 - 1.81 Polarizing Filter
R.I. liquid is included (R.I. liquid you can also reorder)

Digital Gemstone Tester
Each kind of gem has a typical refractive index due to its chemical composition and crystallization structure. Refractive index is one of most important optical parameter, through the parameters you can judge whether the gem is an anisotropic or isotropic stone. This digital gem refractometer is designed to measure the refractive index of gems with high accuracy ± 0.007 RI. With the full range from 1.400 to 3.000 RI, it can be used to test almost all kinds of gem. You don't need to apply RI fluid, just simply put your sample on the test platform and read the result on the LCD very quickly and conveniently. A gem refractometer is the primary and most powerful tool in gemstone identification. Therefore, it is widely used in jewelry stores, gem workshops, museums & collections, auctions, laboratories etc.
Specification:
Measuring range 1.400 ~ 3.000 RI Accuracy: ± 0.007 RI
Working temperature 10 ~ 28°C (50 ~ 82.4°F)
Power source 1 x 9V battery (not included)
Size L105 x W60 x H35 mm
No refractometer oil needed Read results on LCD Easy and simple to use
Included two Scale Sample, one Cleaning Cloth and Carrying Pouch
Weight 339gram

Metal Analyzer - Test purity of precious metal
Metal analyzer designed for jewelry industry, testing laboratory etc for to testing precious metal such as gold, silver and platinum of his purity and to see if genuine or not. It show the result in carat percentage and also gram with a precision of 0.005 gram. Using a tank with water or also alcohol as medium which need a head up time from about 15 minutes. With the included RS-232 interface It's convenient to connect your PC and print out the test result. Measurement range: 0.005g~300g;
Accuracy 0.001g/cm³, testing time 10 seconds. Following products can't be tested:

1. Products of which inside is hollow (if water can be allowed to get access into the hollow, it can be tested)
2. Products set with precious stones.
3. Products of which the density is very close to precious metal. No need to bundle samples, hollowing value can be displayed precisely in two procedure.

1 Carat value, percentage content, density for gold
2 PT value, percentage content, density for platinum
3 S value, percentage content, density for silver
4 percentage content, density for other alloy.
