Things to know before buying a lab-grown diamond

Natural diamonds have been falling in demand due to their costs and ethical implications. This dip has resulted in the limelight being on lab-grown diamonds. With the same elemental makeup (tetrahedral atoms of carbon tightly bound together) as natural diamonds, lab-grown variants make this precious stone much more affordable and accessible to the general public. Read on to learn a few things everyone needs to know before buying a lab-grown diamond.

What are lab-grown diamonds?
Lab-grown diamonds (also known as lab-created, synthetic, artificial, cultivated, or cultured diamonds) are human-made diamonds. These are visually, physically, and chemically the same as natural diamonds.
Unlike natural diamonds, however, lab-grown diamonds are not centuries old. Extreme pressure and temperature conditions formed natural diamonds billions of years ago. By contrast, lab-grown diamonds are extremely new and made by replicating similar conditions in a controlled environment over a few weeks.
This can be done via two different methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). These technologies allow business owners to mass-produce diamonds, thus lowering their prices and making them more affordable.

Are lab-grown diamonds real?
Yes! Lab-grown diamonds are classified as real diamonds. This does not include diamond simulants such as cubic zirconia. Although many people question their validity, lab-grown diamonds are made from the same materials as mined diamonds, giving them similar characteristics. These qualities make it difficult to spot the difference between a lab-grown and mined diamond with the naked eye.

Features to look for in a lab-grown diamond
Whether lab-grown or natural, there are certain features that one should carefully consider when buying a diamond, as they impact its overall quality and price. These are:

Carat
The word ‘carat’ is used to measure the weight of the diamond, where one carat is defined as one-fifth of a gram (0.20 grams). It also relates to the size of the diamond.

Clarity
This is used to refer to the purity of the diamond. During the formation process, diamonds can develop several blemishes or flaws, such as foreign particles or cloudiness, that could lower their value. A diamond graded flawless (FL) is considered the most desirable and precious.

Color
Nitrogen can cause discoloration during the diamond formation process, making it appear yellowish. A flawless or perfect diamond is completely colorless. The color is graded on a scale from D to Z, where D marks the most colorless and valuable varieties.

Cut
The ‘cut’ refers to the stone’s shape, geometry, and finish. Since synthetic stones are more consistent than natural diamonds, they are considered easier to cut, maximizing their fire, brilliance, and scintillation.

Wear and tear of lab-grown diamonds
Diamonds are the hardest element found in nature. Since the chemical makeup for lab-grown and natural diamonds is the same, they also have the same physical strength. As a result, they do not chip or wear away any faster than natural diamonds. They neither change or lose color over time nor their shine or sparkle. These factors make them quite durable and an ideal choice for daily use.

What is the depreciation value of lab-grown diamonds?
On average, lab-grown diamonds cost around 30-40% less than mined diamonds. These prices have been dropping over the past few years because lab-grown diamonds do not have a high resale value.

Right after the purchase, the value of lab-grown diamonds may drop to 10% of their price or even lower (this value is around 30% for natural diamonds). However, since these values keep fluctuating, resellers may be able to get a reasonable price for their lab-grown diamonds in the secondary market.

Sustainability and ethics of lab-grown diamonds
Apart from price, the most significant selling point for lab-grown diamonds is the ethics and sustainability factors. There has been a long history of issues with natural diamonds due to the extreme working conditions. Coupled with mining practices that damage the environment, this has led to a massive paradigm shift, resulting in more people opting for lab-grown variants.
However, although lab-grown diamonds have a smaller ecological footprint, one must insist on questioning their origin. This is because lab-grown diamonds are being mass-produced in several parts of the world without considering the overall energy use.

If sustainability is a major concern, buyers must ask the following questions before buying diamonds:

Were the diamonds produced in the country?
Were there any carbon offsets during the production process?
Where are the diamonds cut, cleaned, and polished?
Do they come with sustainability certification?
Can their supply chain be traced?
Is there proof of a “net zero” impact during their growth?

Are lab-grown diamonds truly rarer than natural diamonds?
Neither natural nor lab-grown diamonds are considered rare anymore. A common choice for most engagement rings and other jewelry pieces, diamonds have long been dethroned from being the ‘rarest’ jewel. However, if rarity is an important factor behind one’s choice, one may want to look at colored diamonds, like red, pink, blue, and green diamonds. These diamonds are incredibly expensive and are mined in different parts of the world.

To conclude, although lab-grown diamonds have been around for a few decades, they are only now receiving their due credit and being celebrated for their design, form, and process. Thanks to their accessible price point and sustainability factor, they also align well with the mindset of the younger generations.

Important things to know about kidney problems

Important things to know about kidney problems

Kidney diseases are some of the most common and life-threatening conditions that affect patients worldwide. These diseases lead to kidney function failure over time. It can be caused by various factors, including environmental toxins, genetic predispositions, and unhealthy lifestyle choices. Kidney disease can lead to severe health complications such as acute renal failure (ARF), chronic kidney disease (CKD), or chronic renal failure (CRF). A healthy kidney is a sign of a healthy body and lifestyle. The function of the kidney The kidney is an essential organ that performs many functions in the body. It filters the blood, removes waste products and excess water from the body, and helps maintain a person’s balance of electrolytes like sodium and potassium. Kidneys help maintain their normal levels of salt concentration which is essential for the proper functioning of every cell tissue in the body because, without adequate amounts of salt, no cells can function properly. The kidney also plays a vital role in regulating blood pressure and volume by keeping them at appropriate levels through urine production. The kidneys also regulate fluid balance in your body by removing excess water from urine and adding extra water into the urine when necessary for your body tissues not to be dehydrated.  Kidney failure is when a person’s kidneys cannot function properly due to disease or injury; this condition can be fatal if left untreated.
Modifying homes for people with poor vision

Modifying homes for people with poor vision

One of the top reasons for low vision and blindness in people over 55 is macular degeneration. Macular degeneration causes loss of vision due to damage to the macula in the retina of the eye. It can be difficult for people with this condition to live in inaccessible homes. So, to ensure ease of maneuverability for people with macular degeneration or similar conditions, here are 13 tips to make a home low-vision friendly. Use clear and contrasting colors for walls The key to making a low-vision-friendly home is using light and dark colors. Dark colors can be complex for those with low vision, but if used intelligently, it can make all the difference. The answer lies in how light reflects off certain surfaces. If you have a bright yellow wall with black trim around it, then any space adjacent to it will be illuminated by daylight coming through windows above them. Contrasting shades like white or black help keep things cooler by reflecting out more heat than they receive from direct sunlight. Place essential items in your line of sight Ensure that important items, such as mobility aids, phones, and other necessities, are within your line of sight and not obscured by something else in the room.
Key things to know about macular degeneration

Key things to know about macular degeneration

Macular degeneration is an eye disorder that affects the macula, a tiny part of the retina that provides sharp central vision. The most common kind of this disease is age-related macular degeneration (AMD), which affects many people in our country over 60 years. While there is no cure for macular degeneration, several treatments and lifestyle changes help manage the symptoms and improve your vision so that it does not interfere with everyday life. What are the types of macular degeneration? There are two common types of the condition: Wet or exudative macular degeneration This is the more common type. It occurs when the tiny blood vessels in front of your retina get damaged and leak fluid into your eye, causing swelling, redness, and dampness. The condition can affect your central vision and cause blurry patches in the center. Central vision is the area you see directly in front of you. Dry or atrophic macular degeneration Also known as senile macular degeneration, this condition occurs when the retina does not receive sufficient oxygen due to damage from aging; it results in a breakdown of the central part of the retina (the photoreceptors). What causes this eye disorder? The risk factors include genetics and lifestyle ailments, such as high blood pressure, high cholesterol levels, and diabetes.

Nasal polyps – Symptoms, causes, and management

Nasal polyps can be a symptom of an underlying condition or occur independently. The visible signs and symptoms of nasal polyps include congestion, runny nose, loss of smell, and pressure or pain around your eyes and cheeks. A deviated septum may contribute to nasal polyps. However, they can also occur in people who do not have this condition, such as athletes who blow their noses frequently during exercise routines. Read on to learn more about nasal polyps. What are nasal polyps? Nasal polyps are small, soft growths that develop in the lining of the nasal passages and sinuses. They are also sometimes called nasal tumors or nasal corking. They are not cancerous, contagious, or caused by allergies. Nasal polyps may also be associated with other conditions like chronic rhinosinusitis (CRS), allergic rhinitis (AR), chronic sinusitis (CS), and asthma. Nasal polyps typically develop before the age of 40, and they do not usually cause symptoms until they grow larger or become inflamed or infected.  However, large nasal polyps can block airflow through your nose. If this happens, you may experience sinusitis, headaches, and a stuffy or runny nose. You may also experience difficulty breathing through one nostril at a time if large polyps block the other nostril completely.

Afib – Types, causes, symptoms, and management

Atrial fibrillation (Afib) occurs when the usually stable and regular electrical impulses in the heart’s upper chambers (atria) begin firing chaotically, causing them to quiver or twitch (fibrillate). This can cause blood accumulation and clotting in the atria. These clots can reach the lungs through the blood vessels and cause pulmonary embolism or can reach the brain, resulting in a stroke. Let’s look at the forms, signs, and causes of Afib and its treatment options: Types of atrial fibrillation Afib can be classified as one or more of these: First-diagnosed Afib: Regardless of symptoms or the number or length of episodes, this refers to individuals diagnosed for the first time with Afib. Asymptomatic Afib: This condition is also called silent Afib, given the lack of signs or symptoms. A random electrocardiogram (ECG) could reveal asymptomatic atrial fibrillation. Paroxysmal Afib: Two or more episodes of the conditions that spontaneously resolve within a week are categorized as paroxysmal Afib. Persistent Afib: This refers to two or more episodes of atrial fibrillation that last seven days or more. Long-term persistent Afib: If the condition persists for more than a year, it is referred to as long-term persistent Afib. Permanent Afib: This is a chronic condition that cannot be managed using common treatment options.

How to reduce sugar intake and manage blood sugar

It is a known fact that too much sugar can be devastating for your health. When blood sugar is high, the body produces more insulin, which can lead to several health complications, including prediabetes and diabetes. So, you must cut down on sugar. Choosing healthy snacks and increasing fiber and probiotic intake can help. Moreover, regular exercise is essential. Here are a few tips to lower sugar intake and manage blood sugar levels naturally. Avoid carbohydrates A high intake of carbohydrates has a substantial impact on blood sugar levels. The body breaks down carbohydrates into sugars like glucose, which enters the blood. While the body requires glucose for energy, an excess can be harmful. As the amount of glucose increases, so does the amount of insulin produced by the body, leading to a greater risk of lifestyle disorders. Some foods with an abundance of carbs to stay away from are potato chips and donuts. Control your portion size If you are dealing with frequent blood sugar spikes, monitoring portion size can help. When you eat a large meal, blood glucose increases suddenly. To avoid this, eat smaller meals. You can opt for five to six small meals per day instead of two or three large ones.

11 management options to keep anxiety at bay

People with anxiety disorders regularly and excessively experience fear and panic in everyday situations. If unchecked, anxiety can impair normal functioning and degrade the quality of life. One must consult a health expert if anxiety is affecting their social life. But first, ensure that any physical health issues are ruled out before consulting them. Most individuals with anxiety disorders need medication or therapy, but coping strategies and lifestyle decisions can also be helpful. Stop and take a breath When you experience an anxiety episode, take a moment to think about what is making you feel uneasy. Usual anxiety symptoms include concerns about a recent or distant event. For example, you can worry that something wrong will happen to you in the future. Or, you can still be upset about something that has already happened in the past. But, whatever your concerns, most anxiety issues stem from not focusing on the present. The next time you feel nervous and get distracted from the present moment, sit down and take some deep breaths to reclaim your composure. You can regain balance and return to the present moment by pausing and taking a few deep breaths. If you have the time, consider advancing this practice by experimenting with breathing techniques.
