                    Refractive  Index is one of the most important optical parameters  used to identify and authenticate polished precious  and semi-precious gemstones. This Gemological refractometer  is a low cost, lightweight measuring instrument used  by jewellers and traders of gemstones   to measure polished stones over a refractive index  range of 1.30 to 1.81 RI. The instrument can also  be used to identify whether a particular stone is Isotropic  or Anistropic (uniaxial or biaxial).

                    Features: 
                    1. Can identify singly & doubly gemstones quickly  and accurately.
                    2. Uniquely  designed, low battery consumption and portable.
                    3. Approved  by strict quality and safety standards for long  and trouble-free life.
                    4. Guaranteed  high quality and accurate testing results.
                     
                    Description:

                    Measuring Range: 1.30-1.81 R
                    Accuracy: ±0.002
                    Main Color: Black
                    Weight: About 330g
                    Size: 11 * 3 * 6cm
                     
                    Package Includes:
                    1 x Gem Refractometer
                    x Button Cell
                    x Oil
                    x English Manual

                    Operating Information:
                    1. Open the upper cover then wash the gem and prism with alcohol.
                    2. Lay the instrument on the worktable. Drop a little bit of special refractive oil onto the surface of prism and press it by a thin glass bar. (Be sure not too much or too little)
                    3. Make sure the ground surface of gem to be measured is close to the prism, press it again lightly, let the refractive oil be evenly distributed between the two surfaces then close the upper cover.
                    4. Press the light momentary switch, make sure that the internal light source is turned on when testing.
                    5. Move the eyepiece up and down and adjust the diopter accordingly. By this time you can see a light/dark boundary in the viewing field. The gradation (shade) on which the boundary located is called the refractive index of gem.

                     
                    Notice:
                    1. Please understand the product might have some colour difference due to different monitors and scenes.

                    Customer Q&As

                    How do I maintain and protect jewelry?

                    • Everywhere you look, people are wearing a vast variety of jewelry - necklaces, bracelets, earrings, etc. Usually, they use their color faded, scratched their stones ...
                    • How to avoid the damage? Tips for maintenance and spare them the ravages of time.

                    Always:

                    • 1. Apply lotion, cosmetics, hairspray and perfume before dressing in jewelry.
                    • 2. When undressing, wipe each piece with a clean soft cloth to remove oils and perspiration.
                    • 3. Compare your hand circumference to the chart below. Purchase a bangle with diameter that is next size up from your actual hand measurement.

                    Never:

                    • 1. Never wear jewelry when doing physical work such as housekeeping, gardening or exercise.
                    • 2. Never expose jewelry to household cleaning products.
                    • 3. Never expose jewelry to chlorine swimming pools or hot tubs.

                    Tips for Cleaning:

                    • 1. Follow the instructions appearing on the label or box.
                    • 2. Clean in a secure location, not the rim of a sink where a piece may slip down the drain.
                    • 3. Use only a soft brush, never sharp or hard objects, to remove dirt or particles.
                    • 4. Clean your jewelry often; lotions, soaps and skin oils alter the optical properties of diamonds and gemstones, causing them to look dull.
                    • 5. Seriously soiled jewelry should be cleaned professionally.- Clean diamond jewelry with a soft brush dipped in warm water and mild detergent; rinse under running water.
