How Can We Help?

Almost all diamonds graded by GIA, IGI and HRD are laser-inscribed on the girdle with a unique identification number.

Every diamond purchase comes with a certificate from an independent laboratory: GIA, IGI or HRD.

Yes. You can buy our loose diamonds without a setting.

Yes, absolutely. 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”, the US government agency responsible for consumer protection) has placed lab grown diamonds on an equal footing with mined diamonds, recognising both as genuine diamonds.

Yes, lab grown diamonds are graded and certified to the same standards as natural diamonds by the leading international institutes in the industry. These institutes issue certificates that clearly distinguish lab grown diamonds from natural ones, usually with a different background colour and a certificate number beginning with "LG", while the description states "LABORATORY GROWN DIAMOND".

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

Certainly! There is a significant difference between lab grown diamonds and diamond simulants. Simulants such as cubic zirconia or moissanite are synthetic crystals with a different chemical composition from diamonds and a different crystal structure. As a result, they differ from diamonds in durability, brilliance and appearance. Lab grown diamonds, on the other hand, are not imitations: they are real diamonds with the same chemical composition as natural diamonds. They therefore have the same brilliance and hardness as diamonds mined from the earth.

No. Just as with natural diamonds, the lab grown diamonds on sale vary in quality. Although they are produced in controlled environments, every stone has its own unique quality characteristics. To ensure transparency and reliability, every diamond comes with an international gemmological certificate and a video showing its distinctive features.

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

Natural diamonds are valuable because of their rarity. Lab grown diamonds, however, have value in terms of beauty and durability. Lab diamonds bring lasting brilliance to every kind of jewellery. Because lab diamonds have no inherent rarity, they are priced lower than natural diamonds.

There are several reasons to choose lab grown diamonds: Ethics: lab grown diamonds are considered an ethical choice, as they do not involve mining, which can be associated with problems such as child labour and environmental damage. Sustainability: producing diamonds in a laboratory requires fewer natural resources than mining, reducing environmental impact and contributing to sustainability. Controlled quality: lab grown diamonds are produced in controlled environments, which allows greater control over the quality and purity of the diamond. Accessible price: lab grown diamonds tend to be more affordable than natural diamonds, offering high-quality jewellery at a more accessible price. Personalised options: because lab grown diamonds can be produced on demand, there are more options for tailoring the diamond's characteristics to the customer's preferences. In short, lab grown diamonds offer an ethical, sustainable and high-quality alternative to natural diamonds, making them an attractive choice for many conscious buyers.

Lab grown diamonds suit a wide range of jewellery, just like natural diamonds. Popular options include: Engagement rings and wedding rings: lab diamonds are an excellent choice for engagement rings and wedding rings, offering beauty, brilliance and durability without the high cost associated with natural diamonds. Earrings: lab grown diamonds can be used to create stunning earrings, classic or modern depending on the design and style you prefer. Necklaces and pendants: a lab diamond can be the perfect centrepiece for a necklace or pendant, adding a touch of elegance and sophistication to any outfit. Bracelets: lab grown diamonds can be set in precious tennis bracelets that add a touch of luxury to the wrist. In short, lab grown diamonds lend themselves to a wide range of jewellery, offering the elegance and beauty of natural diamonds at a more accessible price.

Lab diamonds are most commonly made using one of two processes: chemical vapour deposition (CVD) or high pressure, high temperature (HPHT). Both methods produce rough diamonds which, once cut, are identical to natural ones.

Buying lab grown diamonds can be considered a good investment, depending on the customer's priorities when it comes to jewellery. These diamonds offer the same optical and chemical properties as natural diamonds, but at a much lower cost. However, it is important to bear in mind that their appreciation in value over time may differ from that of natural diamonds, and will depend on various factors such as the market and current trends.

No. Even an experienced gemmologist cannot identify lab grown diamonds from their inclusions alone, even after careful analysis under the microscope, except in rare cases where the inclusions are typical and characteristic of how the crystal formed. Specialist equipment is needed for accurate identification.

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

Because lab-made 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 diamonds significantly more affordable than natural ones. Lab grown diamonds also offer other advantages, such as ethical and environmental considerations.

Lab grown diamonds and lab grown diamond jewellery can be insured. Although Bon Gioielli does not offer insurance policies directly, it provides its customers with a gemmological appraisal and a certificate of authenticity for the product purchased. This detailed documentation allows customers to give their personal or home insurer all the information needed to ensure adequate cover.

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 are diamonds created in a controlled environment inside a laboratory. They are genuine diamonds, with the same durability and beauty as natural diamonds. The main difference is that lab grown diamonds are produced artificially over weeks or months, rather than forming naturally over millennia deep within the earth.
