CVD diamonds, or chemically-grown diamonds, are becoming increasingly popular in the jewelry industry. These stones are physically, chemically, and optically identical to mined diamonds, with one key difference— they are grown in a laboratory rather than being mined from the earth.
HPHT diamonds, or high-pressure, high-temperature diamonds, are a relatively new type of diamond on the market. While traditional diamonds are formed naturally over time, HPHT diamonds are created with an artificial process in a laboratory. This process involves using extreme heat and pressure to simulate the natural diamond-forming process and create these beautiful stones.
So why are CVD and HPHT diamonds attractive to buyers? Well, for starters, they can be more affordable than their mined counterparts. Because these stones are grown in a lab, the cost of producing them is lower. This allows companies to price them more competitively, making them more affordable for consumers.
In addition to being affordable, CVD and HPHT diamonds also boast superior clarity and color. This is because the production process involves carefully-controlled growing conditions. These conditions ensure a higher level of clarity and color consistency than what can be achieved with mined diamonds.
HPHT Diamonds are becoming increasingly popular as a real alternative to mined diamonds. Since HPHT diamonds form in a laboratory, they come in a variety of shapes, sizes, and colors. This makes them a great choice for anyone looking to create a unique and personalized piece of jewelry. They tend to have slightly different optical properties than traditional mined diamonds and can be found in a variety of colors, such as yellow, blue, pink and more. HPHT diamonds are especially common in the luxury jewelry market, as they are often of higher quality than mined diamonds.
Lastly, CVD and HPHT diamonds are often seen as being more ethical than mined diamonds. It’s estimated that one-third of all diamonds are mined in high-conflict areas, potentially contributing to child labor, human rights violations, and environmental devastation.
All in all, CVD and HPHT diamonds are a great option for anyone looking for a beautiful, high-quality diamond at an affordable price. With their superior clarity and color, ethical sourcing, and lower cost, these stones are becoming increasingly appealing to buyers in the jewelry industry.
What are some of the main differences of CVD vs. HPHT lab diamonds?
The difference is in how it is grown and created.
CVD diamonds (chemically vapor deposited diamonds) are grown in a lab using a technique that involves the decomposition of gaseous carbon into small crystalline particles that stick to a substrate, while HPHT diamonds (High Pressure High Temperature diamonds) are grown by mimicry of the processes which occur in nature, recreating the natural high pressure and high temperature conditions.
CVD diamonds typically have lower color grades than HPHT diamonds, whereas HPHT diamonds often have a natural, pleasing yellow hue. CVD diamonds are generally less expensive than HPHT diamonds.
