This bestselling jewelry cleaning stick is a cinch to use and has amassed an impressive 46,000 Amazon reviews—more than 36,000 of which earned a five-star rating—(and counting!), thanks to its ability to restore shine to even the most tarnished cocktail rings that have been sitting in your old jewelry organizer.

Our Evolving Love For Diamonds

We spoke to young Indians about their relationship with diamonds, which are now more personal, a symbol of love for themselves, and an extension of their personality beyond ordinary conventions

Diamond jewellery has long been a symbol of status and wealth. For generations, diamonds have been associated with exclusivity and perceived as a mark of success and achievement. But in recent years, the definition and perception of luxury have evolved, and the relevance of diamonds has changed for millennials and Gen Z, now the largest consumers of diamond jewellery. They are more conscious of ethical and sustainable practices and are looking for jewellery brands that are transparent about their sourcing and production practices. In addition, they are also more aware of their budget and are looking for high-quality jewellery, but not overpriced. This change in perception has influenced brands to pivot to cater to this market.

We spoke to young Indians about their relationship with diamonds, which are now more personal, a symbol of love for themselves, and an extension of their personality beyond ordinary conventions.


I associate diamonds with a feeling of prestige. Diamond is created due to pressure; I associate personally with that as well. If you want to be the diamond of your space, you need to be willing to face the pressure. As the famous saying goes, “No Pressure, No Diamond.”

In our generation, people have understood that there is no right time to buy a diamond except when you feel like you deserve it. Since it’s a status symbol, people tend to reward themselves when they achieve life goals instead of waiting for special occasions. I bought my first diamond ring on my 20th birthday when I hit 400k followers on my Instagram. It was a double celebration, and I decided what

How To Take Care Of Diamonds

Diamonds have been treasured for centuries for their exceptional beauty and durability. And they have been a symbol of love and commitment for decades now. We’ve all, at a point in time, wish to own a diamond for its brilliance and its symbolisation of love. But like anything that reminds us of love, diamonds should be cared for and protected too.

Diamonds, being the hardest substance known to us, can chip at the edges. They can also be affected by heat, chemicals, and everyday wear and tear. They can be stored in an air-tight box with cotton to protect them from scratch.

Also, an important thing to consider is that diamond rings or bangles should also not be worn when applying hairspray, creams or lotions. This can temporarily discolour the diamonds and make them lose their lustre. An important thing to consider is that while diamonds repel water, oils and grease can affect them.

So, how do we take care of diamonds? We got you covered with a detailed pointer for the same.

The most important thing to do is to store one’s diamond jewellery safely in a clean box. During the storage of diamond jewellery, it is advisable to keep it away from other jewellery. Not only can the exposed facets of one’s diamond jewellery scratch the metal surfaces of neighbouring jewellery pieces, but also other softer jewellery materials, such as gemstones and pearls, can get scratched by diamonds.

For the cleaning treatment, one can prepare a small bowl of warm water with a dash of dishwashing liquid and submerge one’s diamond jewellery for some minutes. If one notices some dirt accumulation that is not dissolving in the warm water on its own, one can use a small brush with soft bristles and remove the residue with a

Analysis of a Spectacular 2021 for Diamonds – and a Sobering 2022

In a recently published report titled “2021 Pipeline: Lamenting the Natural Producers’ missed Income,” IDEX Online’s expert analysts Pranay Narvekar and Chaim Even Zohar claim that, following a “dream year” for the natural diamond industry in 2021, this year could prove to be a tipping point for lab-grown diamonds (LGDs).


 The authors begin by analyzing a “spectacular 2021.” 2021, they said, was “probably one of their best years in recent memory” for the diamond midstream and downstream sectors. Polished diamonds, for instance, increased by about 55% compared to 2020 to reach $22.1 billion “due to the bull-whip (or ripple) effect in the pipeline.” 


Meanwhile, The penetration of LGDs in the US market significantly increased in 2021 as more stores “started experimenting with keeping LGD stock,” including LGDs being bought in significant numbers by bridal customers.

In a later section, Narvekar and Even Zohar analyze how the pandemic benefited the sector, as governmental Covid-stimulus packages produced “tangible benefits for the jewelry sector” in the US. The analysts explain that, while many did suffer in 2020 and a stimulus was necessary, “the continued flow of stimulus in 2021 was the cherry on the cake, leading to the tremendous boost for the US economy.” This was especially true for durable goods – a category which includes jewelry” – as consumers “seem to have channeled their excess disposable incomes into purchasing hard assets […].”


In a section titled “Time to pay the bills?” Narvekar and Even Zohar say that “the 2021 party, however, seems to be ending […].” Climbing prices and inflation, coupled with higher interest rates, coupled by the diamond industry’s “usual problems of low growth and insufficient profitability,” have led to a projected growth of “not more than 1-2% for the year at a retail level.”
