This state of the art tester is simple but precise, giving the user a quick "yes/no" reading. Green diamond indicator light illuminates if the stone is a diamond. Housed in a high impact plastic case, it is everything one needs to test diamonds in rapid succession, whether mounted or unmounted.

The simplest Thermal Conductivity tester on the market! Fastest warmup time of under 9 seconds!
complete review Of all the thermal conductivity (diamond testers), this is by far the most simplest unit! All one needs to know is to switch the thumbwheel to the right if stones are over 2.6mm or 0.07 carats for Large Stone testing, if stones are smaller melee below 2.6 mm or 0.07 carats switch thumbwheel to the left for Small Stone testing. This unit has the fastest warm up time of all the diamond tester's that are currently available. I have found that in temperatures between 70-80 degrees, the warm up time is less than 7 seconds. To put this into perspective for potential buyer's that see the Culti Diamond Selector II for sale here on Amazon or Ebay for $7.99-$12.99, the Culti Diamond Selector II takes 23-24 seconds to warm up to begin further testing! The Culti Brand tester takes 13-14 seconds longer to begin accurate testing. Battery Saver Feature for the Diamond Detective Another benefit that I find the RS Mizar Diamond Detective has, is it's ability to alert user that unit is still on. After a period of 3.5-4 minutes of testing, the unit beeps continuously until user presses the on button to remain testing. For those user's that own this unit please read your owner's manual! This isn't a malfunction of the unit! This is a great feature tool that RS Mizar staff came up with. This feature saves battery life, when you forget to turn unit off. All one needs to do is simply press the on button, when battery saver feature alert's user. The probe tip is already heated up and can remain testing. Fixed probe tip If I can recommend any pawnbroker's looking to invest in a decent diamond tester, I would have to urge them to stick with a unit that has a fixed probe tip! Retracting probe tips are too small, and if you slip you can bend the probe tip! RS Mizar designed all of their testers with FIXED probe tips for a reason! The Diamond Detective probe tip diameter is 0.80-0.90 mm which provides a sturdy probe tip, that can tests diamonds as small as 0.01 carat or 1 point. The other MADE IN USA brand tester's have smaller diameter retractable probe tips of less than 0.65mm, Ceres and TRI ELECTRONICS testers have too small of a probe tips, and maybe problematic for a pawnbroker that handles high volumes of jewelry coming in his/her shop. You need a sturdy probe tip that isn't retractable, testing melee stones set in jewelry is so much easier to test with a tester with a fixed probe tip! Choosing the right type of 9-volt battery for the RS MIZAR Diamond Detective I have found that choosing Alkaline batteries for the Diamond Detective is the best approach for this tester. The Super Heavy Duty 9-volt batteries should be avoided. You get a much longer battery life-span out of a choosing a Duracell or Energizer Alkaline battery with this tester. This unit is also designed to work optimally with Alkaline 9-volt batteries. Metal Alert This feature is the "norm" of all the diamond tester's currently available on the market. User must ground metal ring by holding the ring being tested with set stones. RS Mizar Diamond Detective is less sensitive to karat gold or platinum settings, this is a plus if testing melee stones on gallery's that are not part of the lower shank. If you are hitting the prong's, diamond will not be indicated. Other tester's are extremely sensitive to karat gold or any metal settings and may indicate diamond on setting's that are not one solid piece. This Diamond Detective was designed for this sole purpose. Testing Traditional synthetic diamond simulants set in jewelry CZ,YAG, GGG, Strontium Titanate, Rutile Will show NO reaction on the Diamond Detective tester. Testing LARGE synthetic Colorless sapphire can read as diamond if stone isn't allowed to warm up in user's hand. Visually user should be able to tell the difference between LOW R.I. sapphire compared to higher R.I. diamond. This is the only stone that may give user problems. Common sense should also be used Large white sapphire takes a longer time to read as diamond 2-3 seconds. While a large diamond will indicate diamond immediately on the diamond detective. Testing Synthetic Moissanite The Diamond Detective cannot separate moissanite from diamond using thermal conductivity testing, because moissanite has very high thermal conductive properties as diamond. Visually user should understand what moissanite looks like under magnification. Double facet lines will be present if stone is tilted at a 45 degree angle looking through kite shaped bezel facets into through the pavilion. Moissanite's dispersion is nothing like diamond, and it should be very suspicious if user is looking at a very (dispersive) sparkly stone that is loupe clean that indicates diamond on tester. Again, common sense must be used! This tester get's the job done for the user's that are trained in basic gemology or maybe in the business of buying, selling, or appraising diamonds set in jewelry. 5 STARS OUT OF 5Read full review

Don't bother spending money on this item. The 17-19 item is just as good if not better. I thought like a lot of people you get what you pay for, so this time I'd spend more for better quality, this is not the case. I actually think my cheap one worked better than this one. You constantly have to turn on and off, doesn't really detect stone but does chirp when it touches plated materials very annoying. Save your monies I wish I had
