Ultimate Diamond Buying Guide for Tanishq: Your Path to Brilliance

Are you ready to embark on a journey to find the perfect diamond? We understand that buying a diamond is a significant investment, both emotionally and financially. At Tanishq, we are committed to helping you make the most informed decision. This comprehensive buying guide will walk you through everything you need to know about diamonds, ensuring that you select the perfect diamond that suits your style, budget, and occasion.

1. Understanding the 4Cs

Carat Weight

Carat weight is the measure of a diamond’s size. Remember that a larger carat weight doesn’t always mean a more valuable diamond. The other Cs (cut, color, clarity) also play a crucial role in a diamond’s overall brilliance and value. It’s essential to strike a balance between carat weight and other factors based on your preferences and budget.


The cut of a diamond is arguably the most important factor influencing its brilliance. It determines how well the diamond reflects light. A well-cut diamond will sparkle and shine, whereas a poorly cut one may appear dull. At Tanishq, we offer a range of cuts, from classic round brilliants to fancy cuts like the princess, emerald, and more. The ideal cut combines precise proportions and angles for maximum light reflection.


Diamonds come in a variety of colors, but the lesser the color, the more valuable the diamond. The Gemological Institute of America (GIA) grades diamond colors from D (colorless) to Z (light yellow or brown). To the naked eye, color differences can be challenging to detect, especially when the diamond is set in jewellery. Consider the setting type and your own preference when choosing a diamond’s color grade.


Diamonds are formed deep within the Earth, and it’s not uncommon for them to have tiny imperfections, or inclusions, and external blemishes. Clarity grades range from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and blemishes visible to the naked eye). A diamond’s clarity can significantly impact its appearance and price.

2. Exploring Diamond Shapes

The shape of a diamond is a highly personal choice and often reflects the wearer’s style and personality. Here are some of the popular diamond shapes available at Tanishq:


The classic round brilliant diamond is the most popular choice. Its 58 facets are designed for maximum light reflection, creating a dazzling display of brilliance.


Princess-cut diamonds are square or rectangular with pointed corners. They are known for their sharp corners and brilliant sparkle.


Emerald-cut diamonds have a rectangular shape with cut corners. They showcase a step-cut design that highlights the clarity of the stone.


Asscher-cut diamonds are similar to emerald cuts but square. They provide a timeless, elegant look with a vintage flair.


Radiant-cut diamonds combine the brilliance of a round cut with the sleek lines of an emerald or princess cut. They are known for their unique and vibrant sparkle.


Oval-cut diamonds are elongated, offering a unique twist on the traditional round brilliant shape. They can make fingers appear longer and slender.


Marquise-cut diamonds have a football-like shape with pointed ends. They are known for their dramatic appearance and the illusion of a larger size.


Pear-shaped diamonds resemble a teardrop and offer a beautiful fusion of round and marquise shapes.


Heart-shaped diamonds are the ultimate symbol of love and romance. They are perfect for expressing your emotions through jewellery.

When choosing a shape, consider your personal style and the design of the jewellery piece. Some shapes may complement specific settings or occasions better than others.

3. Selecting the Perfect Diamond

Now that you have a good grasp of the 4Cs and diamond shapes, it’s time to choose the perfect diamond that suits your needs. Here are some important considerations:

Budget Considerations

Your budget is a critical factor when buying a diamond. You don’t need to break the bank to find a beautiful stone. Tanishq offers a wide range of diamonds to fit various price points. Remember that you can adjust the 4Cs to meet your budget while still obtaining a stunning diamond.


Consider the occasion for which you’re buying the diamond. Engagement rings, for instance, often call for a classic round or princess-cut diamond. For an anniversary gift, you might prefer a unique shape or color. Tanishq’s diverse selection ensures you’ll find the perfect fit for any event.

Personal Style

Your personal style and the style of the recipient should guide your choice. If the person you’re buying for prefers a vintage look, an emerald or Asscher cut may be ideal. If they’re more modern and chic, a radiant or oval shape could be a better match.

Remember, there’s no one-size-fits-all answer when selecting the perfect diamond. It’s a deeply personal decision, and at Tanishq, we’re here to help you find the right fit.

4. Diamond Anatomy

Understanding a diamond’s anatomy is essential when evaluating its quality. A diamond consists of several key parts:

Table: The flat top surface of the diamond.

Crown: The upper part of the diamond above the girdle.

Girdle: The narrow band around the diamond, separating the crown from the pavilion.

Pavilion: The lower part of the diamond, below the girdle.

Culet: The tiny facet at the bottom of the pavilion, which prevents chipping.

Facets: The flat, polished surfaces that create the diamond’s brilliance.

The proportions and angles of these parts play a significant role in a diamond’s overall appearance. A well-proportioned diamond with precisely cut facets will maximize its sparkle and beauty.

5. Diamond Ideal Cut

When it comes to diamond cuts, the term “ideal cut” refers to a specific set of proportions that have been mathematically calculated to allow the diamond to reflect the most light, thus creating maximum brilliance. An ideal-cut diamond is typically more expensive than one that deviates from these proportions. The ideal cut is characterized by:

  • A table percentage ranging from 53% to 63%.
  • A total depth percentage between 58% and 62.5%.
  • A crown angle between 34 and 35 degrees.
  • A pavilion angle between 40.6 and 41 degrees.

However, it’s important to note that the ideal cut isn’t the only way to achieve a beautiful diamond. Different cuts and proportions can create unique styles and appearances; your preferences should guide your choice.

At Tanishq, our experienced gemologists ensure that all our diamonds are cut to maximize their brilliance, offering you a stunning range of options to choose from.

6. Diamond Fancy Color

While most diamonds are known for their colorlessness, some possess vivid and rare natural colors. These are referred to as fancy-colored diamonds. The Gemological Institute of America (GIA) grades fancy colored diamonds based on their hue, tone, and saturation. Common fancy colors include:

Blue: Blue diamonds are often associated with luxury and royalty. They range from light to intense blue.

Pink: Pink diamonds are highly sought after for their delicate and romantic hues.

Yellow: Yellow diamonds are radiant and can range from pale yellow to deep, vivid shades.

Green: Green diamonds are known for their unique and captivating coloration.

Red: Red diamonds are exceedingly rare and are often considered the most valuable among fancy-colored diamonds.

When selecting a fancy colored diamond, consider the color’s intensity, how it complements your style, and its rarity. Remember that fancy-colored diamonds can be significantly more expensive than their colorless counterparts.

7. Diamond Setting Type

The setting of your diamond significantly impacts its appearance and security. At Tanishq, we offer a range of setting options to suit different preferences and occasions:

Prong Setting: This classic setting uses metal prongs to hold the diamond securely while allowing maximum light exposure.

Bezel Setting: A bezel is a metal rim that surrounds the diamond, offering a protective and modern look.

Channel Setting: Channel-set diamonds are placed in a row between two metal walls, creating a sleek and elegant appearance.

Pave Setting: In a pave setting, tiny diamonds are set closely together, creating a shimmering, paved effect around the main stone.

Halo Setting: A halo setting surrounds the center diamond with a circle of smaller diamonds, enhancing its brilliance and size.

Solitaire Setting: A solitaire setting features a single diamond, often set in a prong setting, for a timeless and elegant look.

The choice of setting should complement the diamond’s shape and your personal style. It’s essential to balance aesthetics with the diamond’s security, ensuring it remains safe in its setting.

8. Diamond Care

Once you’ve chosen the perfect diamond, it’s crucial to care for it to maintain its brilliance and beauty. Here are some diamond care tips:

Regular Cleaning: Use a mild detergent or jewellery cleaner and a soft brush to clean your diamond regularly. This removes oils and dirt that can dull its sparkle.

Storage: Store your diamond jewellery in separate pouches or compartments to prevent scratching. Diamonds are one of the hardest substances on Earth, but they can still scratch other materials.

Avoid Harsh Chemicals: Avoid exposing your diamond to harsh chemicals, as they can damage the metal settings and affect the diamond’s appearance.

Professional Inspection: Have your diamond jewellery professionally inspected and cleaned at least once a year to ensure its security and shine.

Prong Inspection: For prong settings, check the prongs periodically to make sure they are secure and haven’t worn down.

Your diamond is a precious and lasting investment, and proper care will ensure it continues to shine brilliantly for generations to come.

In conclusion, selecting the perfect diamond is an exciting and personal journey. Tanishq is here to guide you through every step, offering an extensive collection of diamonds, expert guidance, and impeccable craftsmanship. With a solid understanding of the 4Cs, diamond shapes, settings, and care, you’re well-equipped to make an informed decision and choose a diamond that will bring joy and beauty into your life.
