GemOro Testerossa Diamond Tester

New!GemOro Testerossa Diamond Tester

This patented GemOro® Testerossa tester features new, advanced, exclusive moissanite testing technology that is capable of identifying the widest range of the electrically conductive moissanite material available, including the new super low electrically conductive F1 moissanite. It is exclusively recommended by Charles & Colvard.

This tester uses a durable, rectractable, precision probe tip to identify, detect, and separate diamonds from moissanite, cubic zirconia, and white sapphires. It has a fast warm-up time, ultraviolet fluorescence detection, and LED stone illumination. The glowing light bar / probe tip cone changes color for quick stone identification: green = diamond, blue = moissanite, pink = sapphire, red = metal alert (warning if the setting is touched).

The sleek ergonomic shape and the intuitive finger grip pads provide increased user-friendliness, hand comfort, and ease of use. The unit's indestructible polycarbonate housing with molded rubber base offers increased impact resistance if dropped.

This tester can powered by micro-USB or with the included 3 AAA rechargeable NiMH batteries. There is an auto-off function to preserve battery life. The user programmable talking voice alert can be selected from 9 languages: English, German, Italian, Spanish, French, Russian, Mandarin Chinese, Japanese, Arabic, or ringtone sounds.

The unit comes with a GemOro® UltraDock® 3 charging station, adjustable test stone magnifier attachment, loose stone holder, multi-voltage 100V-240V AC adapter with micro-USB power cord, and carbon-fiber style carrying case. A lifetime limited replacement warranty on the tester and unprecedented 10-year warranty on the probe tip are included. Designed in the USA.

Note: Gemstone and probe tip must be clean, dry, and room temperature before testing. Roseco is not responsible for direct or indirect damage sustained, or errors in readings by these test instruments.

General Usage Tips:
  • Before using the tester for the first time, charge it overnight.
  • Keep both feet firmly on the floor to help ground the tester.
  • Always wipe stone surface with a clean microfiber cloth (not polishing cloth) to remove any dirt, grime, or oil residue before each test.
  • Always wipe the probe tip across a blank sheet of printer paper (non-waxy) to clean it before each test.
  • Loose stones must be placed in the stone tray with the other hand touching the side of the stone tray to help ground the tester.
  • Do not test jewelry items still stored in a box, display tray, etc. Always hold the piece in your hand to help ground the tester.
