GUIDANCE COLOURED GEMSTONE SIZE

Gemstones manifest the brilliance of nature’s creativity in their dazzling colours and conventional yet unmatched enchantment. Gemstones have been worn for ages, embedded in jewellery and used in numerous adornments. These stones exist in innumerable varieties, differentiated hues and incredible number of colours. Their magnificence is caught in the richness of their stunning colours and dazzle which add a touch of brilliance to the jewels they are used in. Gemstones have been the choice of the elites and the fancy of the craftsmen in all times. Nothing has diminished the charm of gemstones over the centuries.

Gemstones are classified as precious and semi-precious stones. Traditionally rubies, sapphires and emeralds are considered precious gemstones parallel to the diamonds while all other gemstones are classified as semi-precious stones ranging from azurite and opal to jade and topaz. Every gemstone has its own colour and a unique splendour. A gemstone’s attractiveness is defined by its colour which is given to it by its basic chemical composition. Gemstones are basically hued crystals formed by natural combinations of various elements and minerals found in the earth’s underground resources. Gemstones are mined everywhere around the world and differ in variants and some characteristics based on the origin and the environmental conditions.

Every gemstone purchased for use in jewellery and other embellishments are evaluated for five fundamental characteristics that measure its value and quality. These five characteristics include colour, cut, clarity, size and enhancements.

It is very important that you understand the concept of gemstones size if you are purchasing one. The size and carat weight of gemstones are completely distinct aspects of a stone and do not represent the vice versa by any means. It is highly probable for two gemstones with equal mass weight values, measured in carats where one carat equals two hundred milligrams, to have completely different sizes which represent the dimension measures of these stones given by the standard unit of millimetres. A ruby and an azurite might have the same carat value when weighed in a balance but size dimensions in millimetre are more than likely to be unequal by large margins.

You will make a false estimation of a gemstone's size in comparison to another gemstone if you base it on the measure of carat weight of two stones for the basic reason elucidated in the previous section. You should ask the vendor for dimensions measurements of the stone subject to your attention for purchase. These dimensions are conventionally described in millimetres. However, some vendors might describe these in terms of inches fractions. Whatsoever is the unit used, be certain that the dimensions being described are length units which means they describe the size dimensions not the carat weight.

Typically a gemstone consists of a table, a crown, a griddle, a pavilion and a culet. Usually, the diameter length for the round cuts and the length-width measurements of the table for shapes otherwise is given as the primary and at times as the only size dimension measurement which is adequate for comparisons on the general basis.
