Understanding the 7Cs of Diamonds: What Lies Beyond Cut, Clarity, Colour & Carat? The 7Cs of diamonds is an expanded framework that is referred to by certain jewellers. It allows buyers to evaluate diamonds beyond the traditional '4Cs', which include the cut, colour, clarity, and carat. The 4C's continue to remain the global industry standard for quality grading. However, the additional 3Cs take it one step further by focusing on the purchasing experience of the customer and the value they derive from it. These are, namely, certification, cost, and confidence (often interchanged with conscience or character). Read ahead to dive deeper into the concept of 7Cs so you can make your first yet thoroughly informed diamond jewellery purchase.

What Are the 7Cs of Diamonds? The 7Cs of diamonds determine the objective quality as well as the overall appearance of the diamonds in question. Here’s more about each ‘C’ to equip you with the necessary knowledge for making smart diamond jewellery purchases online: 1. Diamond Cut What it Tells You: Diamond cut highlights how masterfully the diamond has been cut and polished. It has been brought to its current dazzling form from an originally rough state. If the diamond cut is perfected, more light shines through, and it sparkles more intensely. How They are Categorised: Here are the categories by which the diamond cut is judged: Excellent or Ideal cut Very good cut Good cut Fair cut Poor cut 2. Diamond Colour What it Tells You: The diamond colour generally refers to how transparent or colourless the diamond is. Owing to the natural presence of nitrogen in these gemstones, they are bound to have a slight yellow tint to them. For collectors or investors, diamonds that have a pale yellow tinge are not as valuable as those that are completely 'colourless'. How They Are Graded: The diamond colour is graded as per a scale of D to Z. D graded diamonds are the ones that are essentially the most transparent, classified 'colourless', and the most expensive. Z-grade diamonds, on the other hand, are the least transparent and the most affordable. To the naked eye, it's pretty much impossible to tell the difference between diamonds that are graded from D-H. A pro-tip to remember while shopping for diamond jewellery would be to opt for G-H grade diamonds. These are much more affordable and look just as brilliant as their pricier counterparts. We, at Mia by Tanishq, extend timeless diamond jewellery options that are perfect for shining daily. Available in GH colour, the 'near-colourless' sparkle fits right in with stunning yellow gold settings. 3. Diamond Clarity What it Tells You: This factor is determined on the basis of the diamond's shine intensity and the number of imperfections (or referred to as inclusions) it has. Note that the 'inclusions' are natural, though; in fact, they lend the diamonds their unique appearance. Socially, fewer inclusions are preferred in diamonds, making them more valuable. How They are Categorised: Diamond clarity is categorised as per how included/flawless they are: FL - IF (Flawless) VVS1 - VVS2 (Very, very slightly included) VS1 - VS2 (Very slightly included) SI1- SI2 (Slightly included) I1 - I3 (Included) 4. Diamond Carat What it Tells You: 'Carat' refers to the diamond's overall weight; it's not indicative of the size. Certain diamonds may weigh the same but be completely different in terms of size, ultimately depending on their cut and shape. How it is Determined: One diamond carat may be 0.2g or 200mg. Carats shall also be referred to in terms of points (e.g., 1 point is equal to 0.01 carats; or a 0.50 carat diamond would be referred to as a '50 pointer' in this case). Beyond these core 4Cs of diamonds, come the additional 3 Cs, which include: 5. Diamond Certification What it Tells You: Make sure that the diamond jewellery you're investing in bears a certificate from an independently certified lab. It's a simple piece of proof that the diamond has, indeed, passed quality checks and been graded by an unbiased team or a professional. With us, at Mia by Tanishq, you can opt for certified natural diamond jewellery, backed by the TATA label. Explore a wide range of brilliantly sparkling, minimalist jewellery, featuring diamonds shining with a light that’s forever-bound. Elevate your everyday looks with a sprinkle of sparkle from Mia. 6. Diamond Cost What it Tells You: Next, decide on how much you're willing to spend on the diamond jewellery beforehand. You can get your hands on a mesmerising statement ring without even going overboard with your budget. Strategically plan to scale back in certain areas to avoid spoiling the overall range you've set aside. For example, you can opt for a G-H coloured, SI2 diamond jewellery. Thus, get better value for your buck while making sure that the aesthetics are on point! 7. Diamond Confidence/Character What it Tells You: This refers to the trust you bestow on the brand or platform. This 'C' is also referred to as 'customer service'. It is an additional consideration you can take into account for an elevated online/in-store diamond jewellery shopping experience. This also gives you the necessary peace of mind to splurge.

Frequently Asked Questions 1. How do inclusions impact the value of diamonds? Fewer inclusions mean higher clarity. Thus, diamonds with fewer inclusions are valued at higher rates. 2. Is a bigger carat size considered to be better? No, a bigger carat size is not necessarily always better. Other factors like the cut, colour, and clarity also heavily affect the beauty of the diamonds. 3. Can I see the diamond colour differences with my naked eyes? As the diamond colour differences are super subtle, you won't be able to spot them with your naked eye. The near-colourless (GH) diamonds look just as clear as the D graded ones.
