Lab Grown Diamonds

Yes, indeed. The main difference between the two lies in their origin. While a mined diamond comes from a mine, a lab-grown diamond, like those sold by Bon Gioielli, has a guaranteed and controlled laboratory origin. Since 2018, the Federal Trade Commission (FTC) has equated lab-grown diamonds with mined ones, recognizing both as genuine diamonds.

Yes, lab-grown diamonds are classified and certified to the same standards as natural diamonds by the best international institutions in the industry. These institutes issue certificates that clearly distinguish lab-grown diamonds from natural ones, usually through a different background color and a certificate number starting with “LG,” while the description mentions “LABORATORY GROWN DIAMOND.”

Since lab-grown diamonds are chemically and optically identical to natural diamonds, they will offer the same longevity and durability. Lab-grown diamonds guarantee a brilliance that lasts a lifetime.

Certainly! There is a significant difference between lab-grown diamonds and diamond simulants. Diamond simulants, such as cubic zirconia or moissanite, are synthetic crystals with different chemical compositions from diamonds and have a different crystalline structure. Consequently, they exhibit variations in durability, brilliance, and appearance compared to diamonds. On the other hand, lab-grown diamonds are not imitations but are actually diamonds with the same chemical composition as natural diamonds. Therefore, they maintain the same brilliance and hardness as mined diamonds.

No, like natural diamonds, there are variations in quality among lab-grown diamonds available for sale. Despite being produced in controlled environments, each gemstone will have its own unique characteristics in terms of quality. To ensure transparency and reliability, each diamond is accompanied by an international gemological certificate and a video illustrating its distinctive features.

No, lab-grown diamonds will not become cloudy over time, unlike diamond simulants. These diamonds will not cloud, yellow, or change color over the years. This is because lab-grown diamonds are identical to natural diamonds both in terms of chemical composition and optical properties.

Natural diamonds have value due to their rarity. But lab-grown diamonds have value in terms of beauty and durability. Lab-grown diamonds provide lasting brilliance to all types of jewellery. Since lab-grown diamonds do not have intrinsic rarity, they are priced lower than natural diamonds.

There are several reasons to choose lab-grown diamonds:
  1. Ethics: Lab-grown diamonds are considered an ethical choice as they do not involve mining, which can be associated with issues like child labor and environmental damage.
  2. Sustainability: Lab-grown diamond production requires fewer natural resources than mining, reducing environmental impact and contributing to sustainability.
  3. Controlled quality: Lab-grown diamonds are produced in controlled environments, allowing for greater control over the quality and purity of the diamond.
  4. Affordable price: Lab-grown diamonds tend to be more affordable than natural diamonds, offering high-quality jewellery options at a more affordable price.
  5. Customization options: Since lab-grown diamonds can be produced on demand, there are more options available to customize the diamond’s characteristics according to customer preferences.
In summary, lab-grown diamonds offer an ethical, sustainable, and high-quality alternative to natural diamonds, making the choice of these jewels attractive to many conscious buyers.

Lab-grown diamonds suit a wide range of jewellery, just like natural diamonds. Some popular options include:
  1. Engagement rings and wedding bands: Lab-grown diamonds are an excellent choice for engagement rings and wedding bands, offering beauty, brilliance, and durability without the high cost associated with natural diamonds.
  2. Earrings: Lab-grown diamonds can be used to create stunning earrings, which can be both classic and modern, depending on the desired design and style.
  3. Necklaces and pendants: A lab-grown diamond can be the perfect centerpiece for a necklace or pendant, adding a touch of elegance and sophistication to any outfit.
  4. Bracelets: Lab-grown diamonds can be incorporated into precious tennis bracelets that add a touch of luxury to the wrist.
In short, lab-grown diamonds lend themselves to being used in a wide range of jewellery, offering the elegance and beauty of natural diamonds at a more accessible price.

Lab-grown diamonds are most commonly made through one of two processes. They are made using either chemical vapor deposition (CVD) or high pressure high temperature (HPHT) methods. Both these methods produce rough diamonds that once cut will be identical to natural ones.

Purchasing lab-grown diamonds can be considered a good investment depending on the buyer’s priorities regarding jewellery. These diamonds offer the same optical and chemical properties as natural diamonds but at a much lower cost. However, it is important to keep in mind that the appreciation in value over time may be different from natural diamonds and will depend on various market factors and trends.

No, even an experienced gemologist cannot distinguish lab-grown diamonds, after careful microscopic analysis, based solely on inclusions, except for rare exceptions where inclusions are typical and characteristic of crystal genesis. Specialized machinery is required for accurate identification.

Yes, lab-grown diamonds sparkle just like natural diamonds. This is because lab-grown diamonds have the same optical and chemical qualities as natural diamonds.

Since lab-grown diamonds can be produced on a large scale, they do not have the same rarity as natural gems. This difference in rarity is reflected in the price, making lab-grown diamonds significantly more accessible than natural ones. Additionally, lab-grown diamonds offer other advantages, such as ethical and environmental considerations.

Yes, jewellery insurance is available for lab-grown diamonds and jewellery containing these gems.

Lab-grown diamonds can be cleaned in the same way as natural diamonds. The best method is to use an ultrasonic cleaner.

Lab-grown diamonds, also known as laboratory-grown diamonds, are diamonds that are created in a controlled environment within a laboratory. They are authentic diamonds, with the same characteristics of durability and beauty as natural diamonds. The main difference is that lab-grown diamonds are artificially produced over weeks or months, instead of forming naturally over millennia deep within the earth.

When looking to purchase lab-grown diamonds, it’s essential to turn to trusted jewelers. Here at Bon Gioielli, we are committed to adhering to the highest standards for all our lab-grown diamonds and jewellery. We offer a wide selection of lab-grown diamonds, certified with the best certification processes available on the market. Our goal is to make the experience of buying lab-grown diamonds easy and stress-free, providing transparent certifications for each diamond and ensuring exceptional customer service.

During the resizing process, small adjustments will be made by adding or removing small amounts of metal to make the ring fit the size you require.
