The Quality of a Diamond is Assessed in 4 ways :

"The Four C's"

Of all the 4 C's, cut is the most directly influenced by man. The other three are dictated by nature. Diamonds are cut into a number of shapes, depending on the nature of the rough stone. The cut or make of a diamond will dramatically influence its fire and sparkle, for it is the cutter's skill that releases its beauty.

Many people confuse cut with the shape of a diamond. The shape is largely a matter of personal preference and is only limited by the skill and imagination of the craftsman. These are the six most popular shapes for diamonds of a carat or more.

Although the majority of gem diamonds appear to be colourless, others can contain increasing tinges of yellow or brown, some of which are referred to as champagne diamonds. It is a totally colourless diamond that allows white light to pass effortlessly and be dispersed as rainbows of colour. The colour grading scale is from totally colourless to light yellow. Rare stones of exceptional colour - green, red, blue, pink or amber - are known as "Fancies".

Almost all diamonds contain minute traces of non-crystallized carbon or small non-diamond crystals. Most are not discernible to the naked eye and require magnification to become visible. Called inclusions, they are nature's fingerprint and make every diamond unique. Minute inclusions neither mar its beauty nor endanger its beauty; however, the fewer they are, the rarer the stone will be.

As with all precious stones, the mass - and therefore the size - of a diamond is expressed in carats. The carat originated as a natural unit of mass: the seeds of a carob tree. Diamonds were traditionally weighed against these seeds, however, the system was later standardized and one carat was fixed at 200 milligrams (1/5 of a gram).

One carat is divided into 100 "points" so that a diamond of 25 points is described as a quarter of a carat or 0.25 carats. Size is the most obvious factor in determining the value of a diamond, but two diamonds of equal size can have unequal prices, depending on their quality. And diamonds of high quality can be found in all size ranges.

How To Care For Your Diamond

Diamonds do need care to keep them at their brilliant best. A clean diamond not only reflects light better, but actually looks bigger than one that's been "dulled" by skin oils, soap, cosmetics and cooking grease. Diamonds have an affinity for grease and should be cleaned once every month to keep their fire at its brightest.

The Detergent Bath
Prepare a small bowl of warm suds with any mild liquid detergent. Brush pieces gently with a tooth brush while they are in the suds. Transfer to a wire strainer and rinse under warm running water. Pat dry with a soft, lintfree cloth.

The Cold Water Soak
Make a half and half solution of cold water and household ammonia in a cup. Soak the diamond for 30 minutes. Lift out and tap gently around the back and front of the mounting with a small brush. Swish the solution once more, and drain on paper. No rinse is needed.

Things Not To Do With Your Diamond
Don't let your diamond come in contact with chlorine bleach when you're doing housework. It won't hurt the diamond, but it can pit or discolor the mounting. Don't wear your diamond when you're doing rough work or doing the dishes. Even though a diamond is durable, it can be chipped by a hard blow along its grain. Don't jumble your diamond pieces in a drawer or jewelry case, because diamonds can scratch each other and also scratch other jewelry. Take your diamonds to your jeweler for a "Check-up" at least once a year. She will check your ring for loose settings and signs of wear. She'll usually give them a professional "shine-up" too. 


Appraisal: An appraisal is an unbiased opinion as to the identity, composition, qualities and values described in an appraisal document, which is the official report of the appraisal. The document must include a detailed description of the item, using recognized terminology and grading systems.

This service should always be performed by an independent appraiser.  An appraisal should contain a quality analysis, description, and valuation of the gemstone or jewelry item.   Appraisers should have a GIA Graduate Gemologist diploma or equivalent, as well as additional appraisal training.  An appraisal should always be independent of the the jeweller you purchase your jewellery from.  There are many jewellers will over inflate the value of their jewellery by providing an in-house appraisal that is actually higher than the item's value just to make their work look good and in order to maximize their profits.  If this value is over inflated then your premiums will reflect the over inflated value.  Always request an independent appraisal.

At Creole Jewellery Design we provide independent appraisals through E L V Jewelry Appraisal Labs of Victoria.  We assure our quality, price and value is relevant and not over inflated.
