The mark of a leader

At Tanishq, we pride ourselves on setting and maintaining high standards. Unlike most other jewellers, Tanishq diamonds are certified by highly skilled graders at our dedicated diamond sourcing office in Bharat diamond bourse - the largest diamond bourse of the world. These carefully graded diamonds are then set into our jewellery. This ensures that you not only receive an exquisite piece of jewellery, but also that you are fully aware of its value.
Every piece of our diamond jewellery comes with a certificate of its value and the Tata seal of trust, for good measure.

Tanishq Jewellery - Diamonds

Ethically sourced

We are very particular about where our diamonds are sourced from. We have seven sightholders, who source rough diamonds directly from major mining companies of the world, thus ensuring that the diamonds are from ethical sources and have not come into the system through companies either directly or indirectly supporting unethical sourcing practices. These rough diamonds are then cut & polished and after a very stringent grading process, they are shipped to our Mumbai diamond sourcing office.

The 4Cs of Diamond Quality


Absence or presence of inclusions in a diamonds determines the clarity grade of a diamond.

The diamonds we select fall in the clarity grades of VVS, VS, SI or I. What further sets us apart at Tanishq is our practice of using only diamonds that belong to the top of the band of the same clarity grade in a particular piece of jewellery, thus delivering best in class diamonds to Tanishq customers. We also do not mix clarity grades unlike many jewellers in the market.

Tanishq Jewellery - Clarity of Diamond


Refers to the presence
of inclusions in a diamond

An important factor in determining the value of a diamond is the number of 'inclusions' or 'blemishes' it possesses. These are indicative of the clarity and purity of the gem. The more flawless a diamond, the better its ability to reflect light.


Cut is the parameter that enhances the diamond’s luster, fire & sparkle. Too often diamonds are cut too deep or too shallow in order to appear larger. However, this lowers the value of the diamond considerably, not to mention reduces its luminosity. As a value factor, cut refers to a diamond’s proportions, symmetry and polish.

That's why our experts take the utmost care to select only perfectly cut diamonds that result in brilliant light performance.

proportions of a diamond

The way a diamond is cut lends to the way in which it captures and transmits light, and eventually its brilliance.


The color of a diamond is all about what you can’t see! The value of a diamond is based on the absence of color, because colorless diamonds are the rarest. Diamonds are found naturally in multiple hues and are hence graded accordingly, with 'colourless' being the most sought after.

a diamond is colourless

The colour that the diamond reflects determines its value and exquisiteness. The absence of colour is usually what makes the most precious stones.


The fourth 'C' stands for carat, which is the weight of a diamond. It is a measure of its value calculated by delicate instruments that follow and are calibrated according to international standards. The carat value of our stones is precisely determined before the diamond is set in our jewellery.

The measure of a diamond's size and weight is what determines its caratage. Coupled with cut, colour and clarity, it decides the ultimate value of the stone.

Cut and crafted with utmost care, Tanishq diamonds come with a certificate of authenticity that states the caratage, colour and clarity of the stone, so you know exactly what you are paying for.

No gemstone expresses human emotions more powerfully than a diamond and Tanishq transforms these precious stones into breath-taking masterpieces, each unique and splendid in design.

Prong setting +

Tanishq Jewellery - Diamond - Prong Setting

A prong setting is the one used, most often, to hold a diamond. The prong setting puts emphasis on the diamond and not the metal supporting it. The purpose of any setting is to hold the stone securely in the mounting and at the same time allow light to enter the diamond for maximum brilliance. This is obviously a delicate balancing act. Needless to say, the more metal used to hold the gem, the more secure it is.

Bezel setting +

A bezel setting is a collar of precious metal wrapped around the diamond. The bezel is attached to the top of the ring and stands up above it, adding height and dimension to the setting. Sometimes the bezel may be 'split' into two sections, arcing around a part of the diamond. This is called a 'half bezel' setting.

Channel setting +

A channel setting is used to set round diamonds. Offering a sleek and elegant appearance, the end result of this kind of setting is a very different look. Setting round diamonds into channels leaves small spaces closest to the metal bars of the channel. By choosing round diamonds, the designer creates a clean line of stones, one with greater brilliance than is possible with baguettes. This also offers a less restrained look and may be more suitable when a ring has a round center stone.

Pave setting +

Tanishq Jewellery - Diamond - Pave Setting

A pave setting is one when the surface of the ring appears to be covered with tiny diamonds. An apt name for this setting, it resembles a street prettily paved with cobblestones. Tiny diamonds are placed in small holes that have been drilled off the ring shank. On a band that does not taper across the top, similar shaped diamonds are placed in such a way that they fill as much of the surface space as possible. Precisely cut diamonds are used for such a setting as they adds to the final appearance of the ring.
