A Guide to the 4 Cs of Diamonds: What You Should Know to Make a Wise Buying Decision
Diamonds always have preciousness not because it’s expensive but because of their attractive appearance. The sparkling gem will melt your heart down when you get to wear them. However, most people think diamonds are costly to afford.
But now, you can have affordable diamond collections from lab-grown diamonds. Diamond buyers Sydney prefer buying lab-grown diamonds more than natural diamonds because they are real diamonds, too, with more detailed specifications.
This article will give you a guideline on buying diamonds, considering the 4Cs (carat, cut, clarity, colour). These are the vital parts of identifying diamonds in the first place.
Know the Carat: The carat size determines the diamond’s measurement. It lets you know how much diamond you will have in that significant diamond jewellery. For example, you are going to buy a diamond ring. The ring will not be entirely made of diamonds. There will be a base of metals.
The metal could be of gold, silver, platinum or others. And the gemstone on top of the ring will be of diamonds. Also, the size variations will detect the amount of diamond you want to have. So, the total measurement is done by measuring the carat size.
The carat size also impacts the price of diamonds significantly. The more the carat size, the more you have to count for the diamond item.
Know the Cut: The cut of the diamond determines how polished the diamond is. You can examine the diamond cut by the light test or microscopic test. When the diamond stone passes the light test, you know you have the pure stone.
The shape and setting of diamonds in jewellery depend on the diamond cut. It’s one of the essential parts of detecting a diamond’s purity in the first place.
Know the Clarity: The clarity or inclusion test is another way to know if you buy suitable diamonds. Usually, lab-grown diamonds have significantly fewer inclusions or clarity than naturally mined diamonds. The explanation is simple: you get organic diamonds mined underneath the earth, and you get diamonds made in the labs.
Knowing the clarity is crucial in determining diamonds. For example, gold buyers look for the gold’s purity by checking its details through different tests. And the same goes for the diamonds too. You get to do the microscopic test or light test for it.
Know the Colour: Diamond colours are also essential to figure out whether you are buying the perfect piece or not. There are differences in colours for lab-grown and mined diamonds. The colour scheme ranges from lighter to darker. When it’s natural, you will not get more than a few significant colours, but lab-grown diamonds will provide you with all the colours you need.
Overall, get your diamond certification when you are up for buying diamond jewellery. It’s the authentication of getting the pure diamonds.

Vice reports that a physicist working at the University of Bristol in the UK has potentially discovered quantum wormholes. Researcher Hatim Salih has proposed an experiment that makes a type of teleportation called “counter-transportation” realistically feasible. However, this isn’t exactly the Star Trek transporter many sci-fi fans have dreamed of over the years. Here’s everything you need to know about Salih’s quantum wormhole experiment.
Salih’s quantum wormhole is a huge scientific breakthrough.
The general theory of relativity of the famous scientist Albert Einstein affirms that hypothetical “bridges” are possible between two points in space-time. However, since 1935, when Einstein presented his theory, the existence of wormholes has been purely hypothetical. However, Salih’s experiment paves the potential way to achieve the longstanding goal of traversing a rift in space-time.
Counterportation comes from “counterfactual” and “transportation” and while similar to teleportation, the two terms are not synonymous. “Counterportation gives you the end goal of recreating an object in space,” Salih said. “[B] but we can make sure nothing happened.”
Although unfortunately, for Salih to achieve true counterportation, they’ll have to wait a few years. The quantum computers necessary to perform the task don’t exist yet in 2023. “If counterportation is to be realized, an entirely new type of quantum computer has to be built,” Salih said. However, development is underway, and Salih hopes to complete it in three to four years.
Wormholes are a classic trope of science fiction in popular media, if only because they provide such a handy futuristic plot device to avoid the issue of violating relativity with faster-than-light travel. In reality, they are purely theoretical. Unlike black holes—also once thought to be purely theoretical—no evidence for an actual wormhole has ever been found, although they are fascinating from an abstract theoretical physics perceptive. You might be forgiven for thinking that undiscovered status had changed if you only read the headlines this week announcing that physicists had used a quantum computer to make a wormhole, reporting on a new paper published in Nature.
Let’s set the record straight right away: This isn’t a bona fide traversable wormhole—i.e., a bridge between two regions of spacetime connecting the mouth of one black hole to another, through which a physical object can pass—in any real, physical sense. “There’s a difference between something being possible in principle and possible in reality,” co-author Joseph Lykken of Fermilab said during a media briefing this week. “So don’t hold your breath about sending your dog through a wormhole.” But it’s still a pretty clever, nifty experiment in its own right that provides a tantalizing proof of principle to the kinds of quantum-scale physics experiments that might be possible as quantum computers continue to improve.
“It’s not the real thing; it’s not even close to the real thing; it’s barely even a simulation of something-not-close-to-the-real-thing,” physicist Matt Strassler wrote on his blog. “Could this method lead to a simulation of a real wormhole someday? Maybe in the distant future. Could it lead to making a real wormhole? Never. Don’t get me wrong. What they did is pretty cool! But the hype in the press?
The success of this experiment could change the field of physics forever.
Additionally, Salih posits that this work is tantamount to the particle acceleration work at the European Organisation for Nuclear Research (CERN). “This work will be in the spirit of the multi-billion ventures that exist to witness new physical phenomena,” Salih said. “[…] But at a fraction of the resources.”
The ultimate goal of the quantum wormhole experiment is to “explore fundamental questions about the universe,” Salih says. And if successful, the experiment could allow scientists to research “higher dimensions.”
