• How can I know if a diamond is genuine?
    • There is no way. Only an expert or someone with a special equipment can tell. All the myths like scratching on glass, looking through it are completely false. It will not help in any way and by scratching you might end up damaging the stone. To be sure, buy from a trusted source, one who will give you a valid certificate for it.
  • What’s the most popular shape for diamonds?
    • The most common, the most popular shape is round. This shape is also the one that exudes maximum brilliance. The best part about round shape is that it gives the diamond the appearance of being larger than it is. Round shape is a preferred choice because this shape conceals abnormalities and yellow hues, giving the diamond a brilliant sparkle.
  • What are the features of a diamond?
    • There are 13 aspects to a diamond.1. Facet: This means the flat sides of the diamond. 2. Table: The octagonal facet on top. Girdle: The white ring that is at the widest part. 4. Culet: The lowest tip or bottom point. 5. Pavilion: The part below the girdle. 6. Crown: Above the girdle. 7. Diameter: The width that is measured through the girdle. 8. Fire: A good diamond scatters reflected light like a rainbow, this is the fire of the diamond. 9. Depth: Height of the diamond taken from the culet to table. 10. Brilliance: What in simple terms is called sparkle. 11. Fluorescence: Again the diamond’s ability to sparkle under certain lights in certain colours. 12. Natural: A rough spot usually found on a raw diamond. 13. Feather: A common irregularity that is shaped like a feather, some call it a crack.
  • Generally speaking how many facets does a diamond have?
    • 58. If the culet is excluded, it’s 57. 33 on the crown and 25 on the pavilion.
  • I keep hearing about the 4 Cs of a diamond, what are these?
    • Colour, Clarity, Carat and Cut of the stone are the 4 Cs.
      1. Carat: In large stones it is called carat. In smaller stones it is called points.
      2. Colour: Not sought after in diamonds as most people prefer the brilliant white. But diamonds come in colours too.
      Here’s a rating of the coloured diamonds. The later the alphabets the darker the colour and the earlier letters denote lesser colour.
      AGS has a similar 0-10 scale.
      • D, E and F – No colour
      • G, H, I & J – Almost colourless
      • K, L and M – Pale yellow or silverish
      • N to Z – Very pale to light yellow
      • Z+ - Comes under fancy yellow
      Typically it is in the E-F to the J-K scale.
      3. Clarity: You will typically find ratings such as this:
      GIA, AGS, Clarity
      Inclusions or imperfections in a stone can range from spots to feathers. Certain inclusions are not visible with the naked eye.
      4. Cut: As we know all diamonds need to go through the cutting process. The dimensions given are a percentage of the width at the girdle. There are widely accepted cuts that have most of the proportions within a few percentage points of an optimum mathematical model. The closest to perfection is the stone that returns the maximum light through the top of the stone, this is what gives it super brilliance.
  • Tell me about the role of colour in the choice of a diamond?
    • If it’s your first diamond, go for white. It is the most wanted colour of the diamond. Even in white, the shades or the levels of brilliance vary. The colour is more obvious in larger stones or if the shape is square or pear shaped, in other words if it isn’t round. Colour can be recognized even with your naked eyes, especially if you have been looking at it every day. Our advise is to go for the whitest diamond you can
      What about clarity?
      Clarity of the stone depends a lot on the cut of the stone. The right cut accentuates the colour and clarity.
  • What is most important of the 4 Cs?
    • In different countries, different aspects are given importance. In India, it is colour followed by cut, clarity and carat. Abroad it is carat, cut, clarity and colour. The right way is to prioritise cut and colour over clarity.
  • Is the shape the same as the cut?
    • No. They are different. The real "cut" as it is referred to deals with the quality of the final product in terms of its maximising the return of light. Four shapes of diamonds are the most popular: Round (or brilliant), Emerald, Marquis and Pear.
  • What is an "Ideal Cut"?
    • In 1919 the famous gem cutter Marcel Tolkowsky developed a specific set of proportions for the round cut diamond. This was called the Ideal Cut. Though Tolkowsky’s specifications was valid only for a particular combination of proportions for getting the ideal balance of dispersion and brilliance. Today the American Gemological Society (AGS) accepts any diamond adhering to a narrow range of proportions and finish as Ideal Cut.
      It is believed that the larger the table, the higher the brilliance at the cost of fire. The ideal cut’s table percentage will be between 53 per cent and 57 per cent with a depth or height of 58 per cent to 60 per cent. If you choose the idea cut, you will shell out at least 20 per cent more for your stone.
  • When it comes to inclusions, what is acceptable and what is not?
    • Avoid flaws that dim the sparkle and is a threat to the life of the diamond. Chips are to be avoided as big chips spell disaster ahead, they will get bigger. If there are large milky/cloudy areas, the stone is a no no. Big feathers like big chips are another flaw to avoid.
  • Is there any way to identify a poor cut?
    • A poorly cut diamond can be identified by many factors. Obvious black spots when viewed from top. Uneven thickness around the stone. White circle in the up view of the diamond.
      How can one then know if a diamond is well cut?
      Look at it directly on the table. If the table and its four corners are square with the sides of the squares bowing in, it is a good cut. An almost perfect square thus is considered a decent cut.
  • Are diamonds best set in platinum or gold?
    • Though platinum is a more expensive material, it is a better material to set your diamond by virtue of being a stronger metal. A diamond is thus more secure with platinum. Also platinum makes a good quality diamond stand out. Gold tends to lend its yellowness to the diamond, which is not desirable.
  • How can I be sure that I receive the same diamond after sent for inspection or remounting?
    • For this you have to first know the inclusions of your diamond that you are giving for remounting. Your certificate will have these details. Then once you get back the diamonds after remounting, get it recertified, this way you will have no issues in knowing whether you are getting back your own diamond.
  • In fancy colours in diamonds, which are the more popular colours?
    • Z+ is the term for fancy, coloured diamonds. The Z ones are rare and therefore most expensive. The most sought after colours are yellow and pink. Though there is an increasing demand for colours like blue, green and orange.
  • How are colour diamond prices determined?
    • The three factors are hue, clarity and richness.
  • Is a fancy coloured diamond judged for clarity just like a white diamond?
    • Unlike white diamonds, where clarity is an important factor, in coloured diamonds small feathers or inclusions do not affect, because of its richer colouring.
  • Do colour undertones affect the diamond's worth?
    • If your diamond has a second undertone, consider yourself lucky. It is an added virtue. However if it distracts from the primary colour then it is not a good thing. As long as the predominant hue isn’t coloured by the secondary colour then it is pretty good to have an undertone.
  • What type of inclusions do colour diamonds have?
    • Usually it is the crystals that give off pretty much the same colours as diamonds.
  • Why are champagne pink diamonds more in demand?
    • They are popular because they are not as expensive as white diamonds and when held up, champagne pink diamonds have brilliant flashes of pink. Also the range of shades varies from light to deep champagne and luxurious cognac.
  • I have heard a lot about the Bow-tie effect, what is it?
    • This effect is visible to the naked eye, and is seen mostly in heart shaped, pear, marquise and oval diamonds. In appearance it is like two triangular dark shapes joined in the centre of the stone. It is considered a negative factor if prominent. Ideally a well-cut diamond will have minimal or nearly absent bow ties.
  • What is a Cubic Zirconia?
    • Man-made diamond simulants with characteristics very close to natural diamonds is what defines the wildly popular Cubic Zirconia. How to tell them apart? A Cubic Zirconia will weigh more than a natural diamond. On the mohs scale of 1-10 for hardness, a CZ is 8.5 - 8.9, while a diamond is 10.
  • What are "synthetic" diamonds?
    • Diamonds are natural formed stones, they are created through extremely high levels of pressure and heat. Real or natural diamonds are said to be between 70 million and 3 billion years old. The only work that is done on it is mining, cutting and polishing, that too by skilled workers, in no other way are they altered. Synthetic diamonds on the other hand are born in a lab. It is ethical for the seller to declare lab grown diamonds.
  • I’ve been hearing of the term conflict diamonds, is it legal?
    • Also known as blood diamonds, conflict diamonds are a part of the illegal trade in diamonds. It exists in many parts of the globe. The money gained in the trade of these diamonds are used for war and other non ethical conflicts. Many brands offer conflict free diamonds, it would be wise to find out if your dealer sells these diamonds before you make a purchase. There exists an illegal trade in diamonds in several parts of the world, and the money is used to fund conflicts (war and other outrages). These diamonds are called conflict diamonds or blood diamonds. Carat Lane is vehemently opposed to this trade in every form. We strive to assure that every diamond we sell is 'conflict-free'.

  • How important is it to buy a diamond that comes with a certificate?
    • Buying a diamond which comes with the certificate of a recognized authority like the AGS, GIA or IGI signifies that your purchase meets the required criteria to have the stamp anywhere in the world as a precious item.
