Diamond Boy

The Diamond Boy is a micrometer for measuring brilliants.

It even measures the finest dust, so it is essential to thoroughly clean the measuring plates before adjusting the device using the screw.

The DIAMOND-BOY has many advantages:

• It is lightweight, weighing only 68 g.

• It is as small as a pocket watch.

• It is easy to handle, and each measurement is readable at a glance.

• It measures even the tenth part of a hair’s diameter.

• It is exceptionally affordable.

Every stone sorter will enjoy using the DIAMOND-BOY. Once tried, they will not want to miss this fine measuring instrument. This always-ready helper should be just as essential as a gemstone loupe or tweezers on the jeweler’s workbench or in the pocket of a diamond dealer, colored stone dealer, gem cutter, or stone sorter. The practical, small size (not bigger than a pocket watch, weighing 68 g) and precision (measurements ten times more accurate than precise) make the instrument indispensable for fine measurements.

Scale Division 1/100 mm, visible even up to 1/400 mm.

Even those who would be satisfied with an instrument that measures in 1/10 mm increments prefer the DIAMOND-BOY with a division of 1/100 mm, as this allows for quicker and clearer readings, even for 1/10 mm measurements.

The DIAMOND-BOY has a measuring range of up to 8 mm. This instrument is therefore primarily designed for small measurements. It is proven that much more small stones need to be measured than large ones (ratio: for one 2-carat diamond, there are about a million smaller stones).

The DIAMOND-BOY is particularly recommended for measuring baguette and carre stones. These measurements are absolutely necessary for fine jewelry and save the setter from the difficult task of balancing. More and more, jewelers are moving away from imprecise measurements with stone sieves. These measurements are no longer sufficient for today’s more precise and finer jewelry work. For example, when stones fall flat with the entire rondiste on the holes, they stay in place; however, if the same stones are set with the rondiste standing high, they will fall through. This results in diameter differences of 2 to 3 tenths of a millimeter.

When setting fine jewelry, it is not the weight that matters, but the exact diameter of the stones. Stones measured with the stone sieve, for example, would be unusable for a fine bezel set in a jewelry watch due to their inaccuracy. Every modern jeweler and setter now orders stones with precise diameters. Whereas they once requested 5-carat diamonds with an approximation of weight per carat, they now order 5 carats in stones with an exact diameter of, for example, 2.2 mm, measured with the DIAMOND-BOY.

The formula engraved on the backplate provides the exact weight of a normally cut diamond without the need for a scale. This fine measuring device is also versatile and can be used for many other fine measurements, such as threads, wires, paper, leather, sheets, balls, etc. Measure one of your hairs – you will be amazed at the accuracy!
