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.

Diamond Fluorescence

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.

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.

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.
