Every diamond, like a human fingerprint, has certain distinguishing characteristics. The universal standard for identifying diamonds determines the quality and value of a diamond according to the 4c’s: Carat,Clarity,Color and Cut. Let the expert of Croesus analyze your diamond, so you know exactly what diamond you are buying.
Color is the second most important of the 4Cs because the color grade directly affects the stone’s appearance. Most diamonds range in color from colorless to slightly yellow. The closer to being “colorless” a diamondthe rarer it is. Perfect diamond it is colorless or near colorless. A white diamond’s quality is equally determined by its absence of color.
Diamonds are graded beginning from D-to-Z color grade. The scale begins with the D color grade, indicating colorless with an ascending presence of color as it moves down the scale to Z color grade, representing light yellow.However, when a diamond color grade does not fall within the D-Z color range, it is then categorized under 'Fancy-Colored' diamonds, ranging from brownish to striking yellow, pink, purple, red, blue and green. There is also a grading scale for fluorescence as some diamonds react to UV light, ranging from Nil, Slight, Medium to Strong.
Croesus only accept diamonds Colorless and near colorless. Each stone is selected individually in order to present only the most beautiful characteristics and high-quality standards of the Maison. Assessed by a professional under 10x magnification, stones are selected with extremely careand stringency.
In gemology, fluorescence refers to the property some diamonds have of glowing when exposed to ultraviolet light. When such diamonds are observed under incandescent or natural light, they can often have a milky appearance—even when they have good clarity. Croesus accepts only diamonds with zero to faint fluorescence and carries no diamonds whose appearance in daylight is compromised by this unique property.
A diamonds cut is essential to its beauty.Cut is the most important scale to highlight all the Characteristics from the stone,one of the principle factors of quality, and the only one influenced by man. The cut is divided to 3 grades:
The Proportions determine the brilliance and the fire of a diamond.
The Polish defines the quality of the finish of the facets.
The Symmetry describes the variations in the parameters which define the proportions.
A diamond’s brilliance lies in the way it plays with light. Its cut, therefore, seeks to maximize its brilliance and sparkle.At Croesus we are committed to crafting the most expertly proportioned diamonds.One of the major reasons why Diamonds are considered a women's best friend is their ability to transmit light and sparkle so intensely. The balance between fire, brilliance and scintillation of a Diamond owes its beauty to the way the Diamond is cut.
A common misunderstanding is that the term 'diamond cut' also refers to the diamond's shape. Cut is what determines how well-cut your diamond is, whereas shape is the form into which it was cut. Diamonds can be cut into various shapes, the best-known of which is probably the round brilliant cut.At Croesus you can select which cut personalize your engagement ring.
Clarity refers to the diamond’s purity. All-natural diamonds show traces of their growth history, which tend to be minor internal characteristics in gem-quality diamonds.The clarity scale reflects the size, number and location of these characteristics when examined with a 10x loupe. Diamonds that have no inclusions visible to the naked eye are of excellent quality. The very best – and rarest – clarity is called ‘loupe clean’. This means that no inclusions can be found even with the loupe.
A Diamond's clarity grade is determined by the position, size, relief, number and nature of these natural inclusions with consideration to the overall appearance of the diamond. Similarly, the more pure a diamond is, the higher its clarity grade, value and rarity. The Diamond clarity scale is divided into 6 categories and are further subdivided into 11 specific grades. It is important to fully understand them individually when searching for the right Diamond.
Flawless (FL) - No inclusions and no blemishes visible under 10x magnification. A Flawless Diamond is extremely rare and almost impossible to find.
Internally Flawless (IF) - No inclusions visible and only tiny blemishes under 10x magnification. An Internally Flawless Diamond is very rare where it is estimated that only 2% of the world's gem-quality Diamonds are considered IF clarity grade.
Very Very Slightly Included (VVS1 and VVS2) - Slight inclusions visible under 10x magnification where it is difficult for even a skilled grader to notice.
Very Slightly Included (VS1 and VS2) - Minor inclusions observed with effort under 10x magnification.
Slightly Included (SI1 and SI2) - Noticeable inclusions visible under 10x magnification.
Included (I1, I2 and I3) - Obvious inclusions under 10x magnification.Its high level of imperfections, possibly visible even to the naked eyes may affect the Diamond's brilliance.
Croesus rejects any diamond with noticeable imperfections to the unaided eye.Diamond inclusions are internal flaws.When Croesus believes that a diamond’s clarity is on the borderline between two grades, we will always assign the stone a lower grade.Those imperfactions from the diamonds are never the same to each stone.Every diamond is UNIQUE.
The weight of a diamond is expressed in carats.The carat is the unit of mass for precious stones generally.The accurate weight is very useful for identifying diamonds.Naturally, having all other factors constant, the larger a Diamond is, the greater its value due to its desirability and rarity.
Croesus offers a wide variety of carat sizes for its diamond solitaires and all our diamonds are always cut to maximize beauty, not carat weight.
