Jewelry Appraisal CenterOur love of diamonds and admiration of their fire and brilliance has given rise to many different cuts of diamonds. While we still see the original styles of diamond cuts – such as the round and emerald-cut, there are many more cuts today, some of them patented by their designers and costing hundreds of thousands of dollars.
The most popular cut for a diamond ring today is still the round, brilliant cut. It was developed in the 17th century in Venice. It is still preferred when the raw crystal is in an octahedron formation. Even though nearly 50% of the stone is cut away in the process, often two stones can be carved from an octahedron. Most unusually-shaped stones are used for fancy cuts, such as a marquise, pear or heart-shaped diamond. The earliest brilliants had 17 facets on the top of the stone and were called double-cut. This was soon improved with stones cut with 33 facets and were called triple-cut brilliants.
In the 19th century, with the development of better gem-cutting tools, more innovations in diamond cutting styles were developed. In 1919, Marcel Tolkowsky combined the art of cutting with the science of light and refraction and published his book, Diamond Design. These relatively recent geometric calculations were the forerunner of much of diamond cutting work today and led to other, more precise mathematical models engineered to enhance the fire and brilliance of diamonds.

There are now cuts such as the princess cut, trillions, ovals, pear and heart-shaped. Some innovative cutters have even fashioned star or butterfly-shaped diamonds! One patented cut, the Ashoka diamond, is an oblong cut with rounded, brilliant ends, and requires a stone 3 carats or larger. It’s an exceptionally beautiful (and pricey!) diamond shape. Tiffany & Co. has also patented a diamond cut known as the Lucida cut. It’s the lucky bride whose fiancé gives her one of these highly coveted stones!

Jewelry hallmarks
Professional jewelry appraisals completed by gemologists and valuers often have to take into account the effect the jewelry hallmarks have on the value of each item being appraised. Do they alter the price, up or down, depending on the hallmark. The simple answer is yes – and no. It depends on the hallmarks themselves and where they come from.

Most people when they imagine a pearl are picturing perfect large round spherical gems, creamy white in colour with a shimmery iridescent surface. The reality is that pearls are usually irregular in shape, each one is different and to find one that is completely round is almost unheard of, not to mention trying to make a whole necklace of pearls that are all more or less the same. Natural pearls are the rarest and most highly valued variety, but nowadays most pearl jewellery is made from cultured or farmed pearls, which are grown on pearl farms… Continue reading What are the Main Differences Between Freshwater and Saltwater Pearls?...
