Interestingly, we buy diamonds in mixed sizes. In addition to colour and clarity, we match diamonds in size. As a result, we sieve and measure tiny diamonds. Some items of jewellery feature many small diamonds. We measure small diamonds to ensure consistency. Small diamonds come in regular millimetre sizes. In addition, we find a record of the depth. As a result, the smallest and largest diamond reading appears. Depending on where you measure the width, most diamonds vary fractionally. Here we see the following measurements.īut why are there three different measurements? To clarify, round diamonds vary fractionally in diameter.
Diamond size appears on the report as shown below. For example, the size, diamond colour and clarity. To explain, this report includes key information. View the chart online Finding the size of a diamond from a diamond certificate Diamond charts (see below) feature most diamond shapes with their carat weight and approximate sizes. Provided you have a diamond size chart, it is possible to estimate the size. It is impossible to find an accurate diamond size without an instrument.
DIAMOND ON MEASURING TAPE HOW TO
How to find out the diamond size without using a gauge This diamond measurement instrument gives an accurate reading of the millimetre size of your diamond. For example, some gauges use a digital display instead of a diamond. The best instrument for measuring your diamond is the Presidium gauge. If you own your own diamond, we require this information to make a ring mount. The diameter gives information to help select the correct size of setting for your diamond. The Presidium gauge gives accurate readings for the diameter and depth of your diamond. Conversely, diamond weight is measured in Carats using a set of scales. Size is determined by measuring the physical size of the stone. Although both are related, they are different. Don’t confuse diamond carat weight with measurementĭon’t confuse the size of a diamond with the weight of the diamond. In detail, both measurements are taken in millimetres. This enables us to measure the diameter and depth of loose diamonds. We use a Presidium dial gauge for this purpose. Diamonds are measured with a precision diamond instrument.
