Tweezers and Gem Holders
Diamonds are forever but not when you can’t grip them. Tweezers are number one on the list because you need to be able to maneuver diamonds and gemstones as you work with them. These are not the tweezers you use to pluck your eyebrows with, although the concept is the same. Instead, these tweezers have a fine tip with a special satin finish on the tips (and inner grip) so as to not scratch the gemstone.
Loupe or Magnifier
You’ll need a 10X or better pocket magnifier to check the quality of gemstones up close. A jeweler specializing in fine estate jewelry and antique jewelry must have a loupe free of distortions. He or she needs to carefully observe the craftsmanship that went into a certain piece in order to determine its year of manufacture and other historic qualities. Look for a loupe that slides into a protective cover - that way the surface won’t be scratched due to wear.
Diamond Scales
These scales are extremely accurate and give the precise weight of the items placed upon them, be they gold or precious stones. It helps to have a scale with multiple weighing units (i.e. grams, carats, troy ounce, pennyweight, pound and ounce) in order to be able to speak to international clients and use their preferred system of measurement. Look for a scale with a low profile and portable compact size. You may need to take it as you go on an adventure for gemstones.
Refractometer
Critical in gem identification, a refractometer is used to give you a clear focus on the refractivity of light within a diamond or clear gemstone It determines the refractive index of a clean, flat, well polished gemstone facet. A good refractometer will give results that are both accurate and precise so be sure to check the market for the most reputable brands.
