- The word carat is derived from carob, the tree whose seeds became the standard for measuring diamonds. A five-carat diamond weighs just one gram.
- The largest diamond ever found was discovered in 1905. Known as "The Cullinan", it weighed in at a staggering 3106 carats, or 612 grams. After studying it for over a year, the famous diamond cutter Joseph Asscher cleaved the stone into three pieces. These were then cut into 105 smaller stones, two of which are still the largest polished diamonds in the world. The largest, at 530.20 carats, is set into the Queen of England's sceptre.

- DON'T think of a diamond's inclusions as a negative thing. Inclusion patterns are the best way to identify your diamond.
- In the old days diamonds were sold in one of two ways: Spotted and Unspotted. Basically you could - or could not - see
flaws with your naked eye. Two of the most common inclusions are crystals and feathers. Crystals are merely minerals
trapped inside the diamond. Feathers are Internal breaks or cracks in the diamond. Even though this sounds terrible they
do not necessarily impair the stone's durability! Remember all of the so called flaws are natural and diamond is a product of mother nature.
- Before the Letter system was introduced and accepted, diamond colour grading had such wonderful old names as "Wesselton ", "Top Wesselton ", "Crystal " and "Cape". The very best colour in diamond was referred to as "River".
- Over the last few years, many new and different diamond shapes have entered the market place.
Many have patented styles and names to secure market share. Wonderful names such the Princess cut, the Radiant cut, the Asscher cut, the Tycoon cut, the Lily cut, the Lucida, Brilliant Lady 21, Passion 8, or Hearts on Fire.
Some are genuinely newly designed cuts, and many are variation of older cuts with new, trendy names. But is it all a fad? The Round (Standard) Brilliant still continues to out-sell all the others combined. Maybe there is a reason why! If you look carefully at the heart shape, oval, marquise and pear shape, you will notice that they are all just variations of the classic- the Brilliant cut.
