Diamond Cut

Diamond Cut
  • The cut of a diamond is considered by gemologists, diamond experts and jewelers to be the most significant characteristic of the 4 C’s. Despite a diamond having the highest-grade color and clarity, it will look dull, lifeless and lacking in “life” or brilliance if the stone is poorly cut. Diamonds should sparkle, meaning that light should be reflected out of the face of the stone.For a beautiful, sparkly diamond, look for “Very Good” and “Ideal” cut grades. “Good”, “Fair” and “Poor” cut grades are not stocked by Natalie Diamonds.
  • Polish and Symmetry: In addition to the proportions of the diamond, both the polish and symmetry affect its beauty and brilliance. Poor symmetry due to uneven alignment of the facets will cause the light to be misdirected and, therefore, not shine out of the face of the diamond.
  • Unsmooth facets or poor polish will cause the surface to look dull and may cause the diamond to look cloudy. The width and depth proportions of the diamond as well as the polish and symmetry will determine the amount of light that is reflected.

Diamond Clarity

Diamond Clarity
  • Extremely rare flawless diamonds do exist, but the vast majority of naturally mined diamonds have imperfections or inclusions, including tiny feathers, scratches, trace minerals and other characteristics that may impair the clarity of the stone.
  • Although not the only aspect affecting the sparkle of a diamond, when the clarity is poor, light will not travel well through the stone. This will make the diamond look dull, cloudy or simply have visible eye sores.
  • Flawless diamonds (FL, IF) may be the rarest and most expensive of all diamonds. However, a diamond with imperfections visible only under magnification will be the best value for your money and will not detract from its beauty.
  • Such “eye clear” diamonds range from SI2 upwards and are recommended for the buyer looking for the very best monetary value without compromising on the look or size of the stone.

Best Monetary Value

  • Diamonds ranging from VS1 to SI2 are the best value for your money, which is why this is the range that we offer and recommend. Diamonds above VS1 will look exactly the same as a VS1 diamond to the naked eye. Therefore, the considerable extra cost does not provide the optimal value for your money. Diamonds below SI2 will have visible imperfections, therefore while they are cheaper, they do not offer the best monetary value for your money due to their reduced quality.

Diamond Clarity Grading Chart

  • • FL – Flawless: No internal or external imperfections.
    • IF – Internally Flawless: No internal imperfections. Very rare.
    • VVS1, VVS2 – Very, Very Slightly Included: Very difficult to see imperfections under 10x magnification. An excellent quality diamond.
    • VS1, VS2 – Very Slightly Included: Imperfections are not typically visible to the naked eye. Less expensive than the VVS1 or VVS2 grades.
    • SI1, SI2 – Slightly Included: Imperfections are visible under 10x magnification and may be visible with the naked eye. A good diamond value.
    • I1, I2, I3 – Included: Natalie Diamonds does not carry diamonds of I1, I2 or I3 grade clarity.

Diamond Color

Diamond Color
  • White diamonds are graded according to the GIA standardized grading chart ranging from D (highest grade) to Z (lowest grade). Loose diamonds may be graded by comparing them under white light to a set of master stone diamonds to determine the exact color grade.
  • Grading laboratories will typically possess a full set of master stone diamonds, one for each color, for maximum accuracy, whereas an independent appraiser or retailer will tend to grade diamonds based on experience or current stock.
  • The value of a diamond is determined primarily by the 4 C’s; Carat weight, Cut, Clarity and Color. The beauty of the diamond will be determined by a combination of the cut, color and clarity, as well as any fluorescence the diamond may have. The most desirable and most expensive color grade is D (besides fancy colored diamonds such as blue and pink).
  • D-E-F color grades are colorless grades and have no visible discoloration, even under lab conditions.
  • G-H color grades are white and will only have very slight traces of discoloration under lab conditions or when compared side by side to higher grade diamonds. In regular light, these diamonds are completely colorless.
  • I-J color grades are very slightly tinted yellow. With well-cut diamonds, these diamonds can have a white face-up, especially when set in yellow gold. Therefore, while being considerably lower in price, they attain similar beauty to higher grades and, therefore, are an excellent value. Recommended for solitaire rings rather than solitaires with accents. Perfect for pendants and earrings, considering their exceptional value.
  • K-L-M color grades are tinted yellow. Unless the intention is for a yellowish colored stone, it is recommended they be set in yellow gold settings for optimal beauty. The color would be especially obvious when set in a piece of jewelry with whiter diamond accents.
  • N-Z color graded are borderline on the light fancy yellow color and should be considered outside the regular “white” diamond chart.

Carat Weight

Carat Weight
    • Larger diamonds are rarer than smaller diamonds as large raw diamonds are less frequently found during mining while very small diamonds are relatively commonplace. As the carat weight of a diamond increases, so does its rarity and its value, thus prices will be exponentially higher as the carat weight rises.
    • A 1.00 carat diamond will be more than twice the price and value than that of a 0.50 carat diamond. The diamond weight will, broadly speaking, also determine the size of the stone. However, a slightly deeper or more shallow cut may result in very slight variations in the size of the “face” of the diamond.


Diamond Shapes

Diamond Shapes
    • Commonly confused with cut, the shape of the diamond is its geometrical form, whereas its cut is more specifically the angles and alignment of the diamond’s facets and how they affect the sparkle and brilliance of the stone.
    • Unlike other essential details regarding a diamond’s specifications, the shape is a matter of personal taste rather than an indication of quality. Rounds and princesses are, generally speaking, the most popular choices. However, “fancy shaped” diamonds may be the right choice for you depending on both your taste and the setting of the piece you are interested in.

Caring for Diamond Jewelry
  • With occasional maintenance and care, you can keep your diamond jewelry as stunning as the day you received it from us.
  • Diamonds are one of the hardest substances known, and polished diamonds are very sparkly. However, over time they can accumulate dirt and need to be brought back to life and full brilliance with gentle and effective cleaners.


  1. Soak your diamond jewelry in a warm solution of mild liquid detergent, such as dish washing liquid and water.
  2. Use a soft brush, if necessary, to remove dirt. Try to use a soft toothbrush so that you remove the dirt that has deposited on the diamond without scratching the gold, as it is a relatively soft metal.
  3. Swish it around in the soap solution. Then rinse it thoroughly in warm water. Make sure the drain is closed or place the ring in a strainer.
  4. Dry with a lint-free cloth.
  5. It is recommended to visit a local jeweler on occasion and have your diamonds tightened in the setting to ensure they are securely in place, especially if alterations, such as ring sizing, have been made to the piece.
