Sometimes, the investment mind wants to avoid fussing over gold prices and making charges altogether. So, whether you're a gemstone lover, collector, investor, astrologer, jewellery maker, or simply someone who adores the sparkle of diamonds and seeks only the best, you're in luck! 

In this blog, we'll delve into everything you need to know about buying loose diamonds and ensuring their authenticity.

What's A Loose Diamond? 

A loose diamond refers to a diamond that is not yet set in any piece of jewellery. It's essentially a diamond that hasn't found its place in a ring, necklace, or any other setting yet. This allows for closer examination of the diamond's quality, characteristics, and potential suitability for various jewellery designs.

But why should you buy loose diamonds? 

Lower Overhead Costs: When you buy loose diamonds online, you're likely to save more thanks to lower overhead costs compared to physical stores, giving you better value for your money.

Retains Value: Certified loose diamonds tend to hold their value longer than those already set in jewellery, making them a smart investment choice.

Quality Selection: Online platforms like Angara India offer a vast array of top-notch loose diamonds in various cuts, carat weights, and grades, ensuring you find the perfect gem for your needs.

Expert Guidance: With gemologists and diamond experts at your service, online diamond shopping becomes a breeze, providing you with valuable insights and assistance throughout your purchasing journey.

Convenience: You can skip the hassle of store visits and traffic jams—shopping for loose diamonds online lets you browse and buy from the comfort of your home, anytime.

Transparency: Online diamond retailers provide comprehensive information, including grading reports and certifications, empowering buyers with the knowledge they need to make confident decisions.

3 Most Important Things To Consider 

There are plenty of benefits to buying loose diamonds, but how can you be sure the stone is genuine? There are some crucial tips to ensure your purchase is completely authentic. 

Here's the most crucial factors affecting the diamond price:

1. Trusted Brands

It's essential to shop from reputable brands with a strong reputation to uphold. While physical stores may have long standing relationships, online brands like Angara, with a Trustpilot rating of 4.6/5, offer top-quality gemstones with the assurance of customer satisfaction. Shopping from trusted brands not only ensures the quality of the gemstones but also provides peace of mind regarding authenticity and customer service. 

2. Certification & Lab-testing Reports

When investing in loose diamonds, always opt for those certified by esteemed laboratories. These certifications offer a thorough evaluation of the diamond's grading and authenticity, ensuring you're making a worthwhile investment. Here are the top three diamond-testing labs in India:

Gemological Institute of America (GIA): Renowned for its advanced testing methods, including the DiamondView (which uses UV light) and GIA iD100, offering accurate assessments of diamond fluorescence and distinguishing natural diamonds from lab-grown ones in seconds.

Solitaire Gemmological Laboratories (SGL): A premier laboratory known for its expertise in testing and grading diamonds, gemstones, and jewelry, equipped with cutting-edge technology and a commitment to integrity.

International Gemological Laboratories (IGL): An independent gemological laboratory in India, blending state-of-the-art technology with extensive professional experience to provide reliable testing and certification services for gemstones and diamonds.

3. The 4’Cs


Diamonds range from colourless to light yellow or brown, with the colourless ones being exceptionally rare. Graded from D (colourless) to Z (light yellow or brown), D-F diamonds are the epitome of sparkle. Sometimes higher fluorescence make diamonds appear even whiter.


Clarity indicates if there are any inclusions (internal flaws) or blemishes (surface marks). Rare diamonds without visible imperfections are highly prized, graded from FL (flawless) to I (included). FL diamonds are like finding a diamond in a sea of coal. The diamond's cut can affect how inclusions are visible, especially in step-cut diamonds like emerald cuts.


Carat measures a diamond's weight, with one carat equal to 200 milligrams. The bigger the carat weight, the higher the price tag, but carat weight alone doesn't determine the price. Cut plays a significant role in how large the diamond appears, as a well-cut diamond can enhance its appearance.


The cut of a diamond defines its brilliance and sparkle. A well-cut diamond reflects light in all directions, stealing the show. Cuts are graded from poor to excellent, with each shape having unique characteristics. Whether you prefer round brilliants, emeralds, or princess cuts, there's a cut to suit every style and preference.

You Can Choose Lab-grown Diamonds Too

Natural diamonds form deep within the Earth over millions of years, which is why they come with a hefty price tag. But if you're not planning to pass it down generations or put it up for auction, there's a wallet-friendly alternative: lab-grown diamonds! Identical in every aspect except for their origin, these gems cost a fraction of natural diamonds while offering the same quality, durability, and sparkle—sometimes even better with fewer inclusions! The choice is yours, just ensure authenticity every step of the way!

1. Why shouldn't you buy a loose diamond and setting separately? 
Some jewellers may hesitate to set a diamond purchased elsewhere, creating complications. However, at Angara, we offer complete customisations, ensuring a seamless process and authentic jewellery every time.

2. Should I buy a diamond as an investment and keep it loose or have it set in jewellery? 
Ultimately, the decision is personal, but it's often more enjoyable to wear your investment rather than keeping it stored away. If you opt to set it in jewellery, there are various options such as pendants, earrings, or engagement rings to choose from.
