Best Diamond Jewelry Stores: Where To Buy Online In UK


hirley Bassey sang it best when she took out her ’70s Bond belt, Diamonds are forever. The magnificent stones were used to adorn royalty and have been coveted by the fantastically rich for centuries. They continue to be the reigning gemstone for engagement rings and wedding jewelry.

One of the reasons they are so precious and expensive is the simple fact that they can take up to 3.3 billion years to form, or about 75% of the age of the Earth.

For those who don’t want to hang around that long, a faster solution is at hand.

What are lab-grown diamonds?

Laboratory-grown, man-made, or cultivated diamonds are identical to those found on Earth, but take less than a month to grow in a controlled environment.

They are made by taking “seeds” (small diamonds) and growing them by applying high pressure and heat so that carbon layers form on them.

They have no environmental impact unlike the process of stones extracted from the earth which can lead to soil erosion, ecosystem catastrophe and deforestation, not to mention triggering outright wars. In addition to light colors, lab-made diamonds can be cultivated in tones that would be considered extremely rare (and expensive) if researched by traditional methods, but they are true carbon copies of natural stones.

Thus, not only are kilometers of lab-grown diamonds more affordable, but they are also an ethical and socially responsible choice.

With sustainability at the top of our collective agendas, it’s no wonder these lab-grown beauties dominate the market as more of us consciously buy.

How to buy diamonds online

There are a few rules about buying diamonds, the main one being the four Cs.

Where do the 4 Cs come from?

Gary Ingram, CEO of The diamond store explains, “This method of valuing diamonds was invented by the Gemological Institute of America (GIA) in 1949. Today, their grading system is the globally accepted standard for measuring the quality of diamonds, and it is used by virtually all jewelry professionals in the world. “

The four Cs of diamond quality

Ingram says, “Diamonds are rare, beautiful and brilliant. But not all of them are alike. Their brightness, size and appearance depend on four quality factors. These are called the “4 Cs” of diamond quality – and they are VSUtah, VScolor, VSlarity and VSarat weight. Each factor is rated separately, but together they establish the overall quality of a diamond.

  • To cut: the expression “a rough diamond” takes on its full meaning when you see the intact state of the stone. It takes a lot of effort to coax it into the dazzling rock that you admire in the storefronts of jewelry stores. Cut refers to how light can refract through it and, therefore, how bright it will shine.
  • Color: not all diamonds are clear, some contain gray or yellow tinges, which are considered flaws. The less color a white diamond has, the more it is worth. That said, there are exceptions to the rule: yellow, pink and blue colored diamonds are valuable depending on the intensity of their color.
  • Clarity: it’s time to take out your magnifying glass for inspection. Most diamonds have flaws and imperfections that affect their price, even though they are invisible to the naked eye. Totally flawless diamonds are incredibly rare and therefore very expensive.
  • Carat: size matters in the diamond world. The larger the rock, the more it is worth, even though it is the same cut, color, and clarity as a smaller stone.

What is the difference between Carat and Karat?

A carat is the unit of weight used to measure the size of a gemstone, such as a diamond. During this time, a karat measures the amount of gold in an alloy. It’s always 24 parts, so for example 18k gold means 18/24 parts gold.

Forget a little black book, consider this your ultimate diamond repertoire for jewelry that sparkles.

How to care for and store diamond jewelry

Whether you opt for a lab-grown or resold natural diamond, these precious jewels require TLC to help them maintain their shine.

Take them off before swimming, bathing, or cleaning the house, and give them the finishing touch after you’ve done your hair and makeup. Hair spray, moisturizer, and perfumes can impact their shine.

A safe is the perfect place to store diamonds if you don’t have a safe in your home. For pieces that you wear every day, keep them away from other jewelry to avoid scratching them – its original box or fabric-lined jewelry box is best. If none of that is an option, keeping it wrapped in tissue paper is a great alternative.
