It is true that diamonds are a girl’s best friend. Even the modest diamond jewellery can turn heads. That is because no gemstone is so spectacularly beautiful, nor does any other gem combine such beauty with such hardness. Diamond is rated a 10 on the Mohs hardness scale. It is just about the hardest substance on earth.
There are some key vocabulary words worth knowing about before buying your diamond.
What’s a Carat?
According to legend, the word carat is derived from the word carob. The seeds of this plant are so uniform that a set number of them always weigh the same, no matter when or where they are collected. This became a standard measure of weight. Today, a carat is 1/5 of a gram or 100 points (cents). Usually diamonds above certain points (usually 0.23 carats) are also called solitaires. 1.00 Carat solitaire makes a perfect diamond for an engagement ring.
The tiny facet found at what would be the apex of the pavilion or the bottom of the diamond is called the culet. However, some gem cutters leave out the culet in a brilliant cut gem.
The crown is the top of the diamond. Several cuts of diamonds such as round brilliant, heart shape, princess cut, emerald cut etc. have a large, flat facet in the crown called the table. The table facet is most visible facet when diamonds are set in ring,earrings or pendant.
The bottom of the brilliant cut diamond is called the pavilion.
The thin line separating the pavilion and the crown is called the girdle. It’s also the widest circumference of the stone. The diameter of a diamond is measured at the girdle of a diamond. The unit for measuring the diameter of a diamond is millimetres. When diamonds are set in jewellery, they are held in place by prongs that often grip them at the girdle.
Diamond Polishing or Faceting
When diamonds are first pulled out of the ground, they are quite dull and may be covered with greyish surface coating. Early gem cutters removed this film by rubbing one diamond against the other. Over the centuries, the art of diamond polishing evolved to allow the diamond to display its great power to refract light. Even today the only thing that can properly polish diamond is another diamond. Polishers often use disks coated with diamond dust to bring out the inner beauty of the gem.
The depth of the diamond is the distance from its top to its bottom. An experienced gem cutter must take into account the depths of the diamond they cut and polish, for if the cut is too deep or too shallow, the gem will not refract light the way it should.
Although most online jewellers educate their customers about diamonds, it’s always a good idea to know the above mentioned vocabulary words especially if you are buying your diamond jewellery for the first time.
Besides understating these basic key words, it is highly recommended that you buy your precious diamond jewellery from reputed jewellers that sell fully certified jewellery made from conflict free diamonds.
