Perfect for jewelers, hobbyists.About This Item:Fast & Safe Detection: The Professional Diamond Selector II is designed for quick, precise, and safe testing. Features an LCD display, LED indicator, and audible alerts to help easily distinguish between real and fake diamonds.Bare-Hand Operation Required: For accurate testing, the tool must be used with bare hands. One hand should hold the diamond, and the other should hold the tester while touching the conductive panel on the back. Gloves or single-hand operation may result in false readings.Beeping on Startup = Initialization Needed: A beep during startup means the tester needs to be initialized. Adjust the sensitivity using the dial to match the diamond’s

size and temperature (default setting: 4 lights at room temperature). Refer to the table on the back of the device for guidance.Metal Warning Tone: The tester works by measuring thermal conductivity. Metals can trigger a high-frequency alert since they conduct heat similarly to diamonds—this helps prevent false positives.Easy to Use – No Experience Needed: Just power on the device, lightly press the probe against the gemstone, and listen for the beep. No sound = fake (e.g., crystal, cubic zirconia), while a beep = real diamond.Important Usage Notes: 1) Do not wear gloves. 2) Avoid testing in windy or extreme temperature conditions. 3) Ideal operating temperature: 10–35°C, humidity below 80%. 4) Always touch the metal panel during testing. 5) Turn off the device after use to conserve battery.Package Includes:1* Diamond Tester Pen1* Leather Carrying Case1* Testing Platform1* User ManualBattery not included (Requires 1 x 9V battery) .cs-head .cs-head .dc-cs:hover ,.dc-dock:hover .dc-cs .dock-rb .cs-top .cs-top @media (max-width:480px) .cs-top }.cs-top .cs-append ,.cs-bottom .cs-append ,.cs-bottom .cs-append , @media (max-width:480px) .cs-bottom }.cs-append ,.cs-bottom .cs-append, @media (min-width:640px) .cs-list-col7 .cs-list-col8 .cs-list-col9 .cs-list-col10 }.cs-list .cs-list:after,.cs-list:before .cs-list:after .cs-list>li .cs-append,.cs-bottom .cs-list-col6>li .cs-list-col7 .cs-list-col7>li .cs-list-col8 .cs-list-col8>li .cs-list-col9 .cs-list-col9>li .cs-list-col10 .cs-list-col10>li .cs-list-col11 .cs-list-col11>li .cs-list-col12 .cs-list-col12>li .cs-list-collapse .cs-list-collapse>li @media (max-width:800px) .cs-list .cs-list>li }@media (max-width:640px) .cs-list .cs-list>li }@media (max-width:480px) .cs-list .cs-list>li }.cs-list .cs-list a .cs-list a:hover .cs-list .cs-list .cs-list .cs-list .cs-list .cs-list .cs-list .cs-list .cs-list .cs-list .dc-cs * .cs-top .cs-append ,.cs-bottom ,.cs-top p:empty+hr hr+span.ebay .dc_tracker_img #ds_div>.dc_tracker_img:last-of-type [data-lid="203142080212"] [data-lid="203142080212"] [data-lid="203142080212"] [data-lid="204144634911"] [data-lid="204144634911"] [data-lid="204144634911"] [data-lid="203135753347"] [data-lid="203135753347"] [data-lid="203135753347"] [data-lid="204348961654"] [data-lid="204348961654"] [data-lid="204348961654"] [data-lid="204200268739"] [data-lid="204200268739"] [data-lid="204200268739"] [data-lid="203638353971"] [data-lid="203638353971"] [data-lid="203638353971"] [data-lid="203049691956"] [data-lid="203049691956"] [data-lid="203049691956"] [data-lid="201917007434"] [data-lid="201917007434"] [data-lid="201917007434"] [data-lid="203152302079"] [data-lid="203152302079"] [data-lid="203152302079"] [data-lid="204837723422"] [data-lid="204837723422"] [data-lid="204837723422"] [data-lid="203529410562"] [data-lid="203529410562"] [data-lid="203529410562"] [data-lid="203136103342"] [data-lid="203136103342"] [data-lid="203136103342"] [data-lid="203535513921"] [data-lid="203535513921"] [data-lid="203535513921"] [data-lid="205126496222"] [data-lid="205126496222"] [data-lid="205126496222"] [data-lid="204272645477"] [data-lid="204272645477"] [data-lid="204272645477"] [data-lid="204144590565"] [data-lid="204144590565"] [data-lid="204144590565"] [data-lid="203142080212"] [data-lid="203142080212"] [data-lid="203142080212"] [data-lid="203135753347"] [data-lid="203135753347"] [data-lid="203135753347"] [data-lid="204537587736"] [data-lid="204537587736"] [data-lid="204537587736"] [data-lid="202973000480"] [data-lid="202973000480"] [data-lid="202973000480"] [data-lid="204450208887"] [data-lid="204450208887"] [data-lid="204450208887"] [data-lid="202777010832"] [data-lid="202777010832"] [data-lid="202777010832"] [data-lid="203136103342"] [data-lid="203136103342"] [data-lid="203136103342"] [data-lid="204823729664"] [data-lid="204823729664"] [data-lid="204823729664"] [data-lid="204144634911"] [data-lid="204144634911"] [data-lid="204144634911"] [data-lid="203371322272"] [data-lid="203371322272"] [data-lid="203371322272"] [data-lid="204009008732"] [data-lid="204009008732"] [data-lid="204009008732"] [data-lid="202792369456"] [data-lid="202792369456"] [data-lid="202792369456"] [data-lid="205054397321"] [data-lid="205054397321"] [data-lid="205054397321"] [data-lid="203152302079"] [data-lid="203152302079"] [data-lid="203152302079"] [data-lid="202879672102"] [data-lid="202879672102"] [data-lid="202879672102"] [data-lid="202575687212"] [data-lid="202575687212"] [data-lid="202575687212"] .dc_tracker_img:last-of-type p:empty+hr hr+span.ebay,hr+*>span.ebay
