Measuring diamonds
Diamond dimensions include its diameter, length, width and depth. These basic dimensions are used to identify stone, analyze proportions and quality of grinding, selecting the right size of the precious stone into a particular jewel.
Record of measurement
For round shapes, "minimum diameter - maximum diameter x depth" is reported. For fantasy shapes, "length x width x depth" is reported.
The most common tools are scales to measure in millimeters
There are many different types of these drawer that can have a mechanical indicator or digital display. Types differ in accuracy and correct measurement.
Advantages over optical machine measurement of diamonds:
- They are portable and cheaper.
- They can be used to measure free and planted stones of any shape and cut.
Notice:
-
These devices come into direct contact with the diamond, so they must be treated carefully to avoid damage or hair of diamond. Some drawers are suspended - if you release them, they close sharply and can damage both the stone and the device.
-
Over time, the measuring surfaces may wear out, which will affect the accuracy of the results. It is important to calibrate these devices regularly and replace it if necessary.
Using the drawer:
To measure the free diamond, place the diamond between the inner part of the drawer.
For a drawer with a mechanical indicator, a tenth of a millimeter and a whole millimeters up to 10 mm show on a small dial. At each full speed, it is necessary to add 10 mm to the measured value. To obtain accurate measurement, it is necessary to add a value from a small dial to that on the main dial. Otherwise, you can notice, for example, 5.20 mm when the actual measurement is 15.20 mm. For mechanical drawer, it is also necessary to estimate the measurement per hundredths.
Digital display drawers can display measurements to hundredths, so an estimate is not needed.
Proper use of the drawer is essential for accurate measuring diamonds and precious stones. Precise measurements are important for many aspects of working with diamonds. Regular maintenance and calibration Šupler will help maintain their accuracy and ensure proper measurement. It is necessary to realize that the accuracy of a specific scorler may vary, a drawer that reliably measured last week this week can have a deviation. Therefore, it is important to regularly check the accuracy of the Šupler with the help of standardized measurements.
