How to measure the size of a jade bracelet

1, soft ruler measurement method: press the tip of the thumb against the root of the little finger, and be careful not to be too tight or too loose. Wrap a soft ruler or a thread around the widest part of the palm. When measuring, if the hand is soft, the lady can measure it tightly. If the hand bone is hard, all she can measure is to tighten the thread.

Measure the size of the jade bracelet with a ruler. The method of measuring palm width with a ruler is simple, and the single error is too big. Put four fingers together and measure the width of the tiger's mouth with a ruler to determine the size of the jade bracelet. The size of the bracelet corresponds to the size of the palm, as shown below.

3. Measuring the size of the jade bracelet with a ruler The method of measuring the palm width with a ruler is relatively simple, and the single error is too large. Put four fingers together and measure the width of the tiger's mouth with a ruler to determine the size of the jade bracelet. The size of the bracelet corresponds to the size of the palm, as shown below.

4. The size of the bracelet depends on the diameter of the inner ring of the bracelet. Keep your thumb and little finger as close as possible. Ask a friend to help you measure the length with a soft ruler and divide it by 14, which is the inner ring of your bracelet. Friends who like to be slightly loose or tight can add or subtract 10 ~ 20mm before and after, not too big.

5. The size of jade bracelet can be measured by soft ruler, ruler and caliper.

How to measure the size of jadeite

The size of a jade bracelet can be measured with a soft ruler, a ruler and a caliper.

First of all, when measuring the size of the bracelet, you can spread out the palm, move the thumb to the root of the little finger, then draw a circle at the widest part of the palm with thin lines, make a mark at the overlapping place, then measure the distance with a ruler, and divide the result by 14, which is the inner diameter of the bracelet.

How to measure the size of jade bracelet?

Measuring the size of a jade bracelet with a soft ruler means measuring its ring mouth or measuring its inner diameter. Put your thumbs together so that the tip of your thumb is close to the root of your little finger, then wrap a soft ruler around the widest part of your palm, tighten it and record the measurement data. Divide this data by 14 to get the inner diameter of the jade bracelet.

Put four fingers together and measure the width of the tiger's mouth with a ruler to determine the size of the jade bracelet. The size of the bracelet corresponds to the size of the palm, as shown below.

Ruler measurement method: the palm is naturally spread out, so that the index finger and thumb form a 90-degree right angle, and the scale of ruler 0 is aimed at the 90-degree angle, and the widest part of the palm is measured.

When measuring the size of the bracelet, first spread the palm, move the thumb to the root of the little finger, then use a thin thread to bypass the widest part of the palm, make a mark at the overlap, and then measure the distance with a ruler. The result is divided by 14, which is the inner diameter of the bracelet.

How to measure the material thickness of jade bracelet

Bracelet thickness: generally measure the thickness of the hand chain, and the thickness from the inner ring to the outermost ring is the thickness of the bracelet. Bracelet width: generally measure the width of bracelet stripes. The width of standard round bracelet is thickness, and the width of peace bracelet and princess bracelet is flat mouth width.

Put your thumbs together so that the tip of your thumb is close to the root of your little finger, then wrap a soft ruler around the widest part of your palm, tighten it and record the measurement data. Divide this data by 14 to get the inner diameter of the jade bracelet.

The detection method of jadeite bracelet is very simple. First, measure the specific gravity (also called density) of the jade bracelet. The specific gravity is the result of dividing the weight by the volume. Take the following jade bracelet as an example: prepare an electronic scale, turn on the power and put the jade bracelet on it. The electronic scale shows the weight as 104g.

Please lubricate it with a lubricant such as hand sanitizer.

The size of a bracelet depends on the diameter of its inner ring. Keep your thumb and little finger as close as possible. Ask a friend to help you measure the length with a soft ruler and divide it by 14, which is the inner ring of your bracelet.

How to measure the thickness of jade pendant

Coin measurement, jade Guanyin thickness measurement method can use reference objects, such as coins. Firstly, the diameter of one-dollar coin is measured, and then the lead is calculated by the circumferential formula. Usually, most merchants will choose coins as the best reference for jadeite.

Under normal circumstances, if it is a jade pendant inlaid with metal chain, the length is within 35mm and the thickness is not less than 5mm. However, if it is a jade ruyi pendant with a lanyard, the length cannot exceed 40mm and the thickness remains unchanged.
