FAQ

It's very easy. Just let us know what gem or jewelry you're after and send us the inquiry to our email at info@laboratory-diamonds.com. We'll get back to you with instructions as soon as possible.

To keep our prices as low as possible and avoid paying fees to payment gateways, we offer our customers the option of direct bank transfer. For example, if you wish to order a lab-diamond or ring from us, we will send you a proforma invoice containing all payment-related information. Once we receive payment confirmation or the payment reaches our account, we consider your order placed and begin work on the setting.

Customers from the USA are not subject to import taxes. For customers from Australia, there is an approximate 17% tax for orders above 1000 AUD. Customers from Europe are also exempt from import taxes. Import taxes apply to customers from all other countries based on their destination. We can help you determine the amount; just let us know.

HPHT = High Pressure & High Temperature CVD = Chemical Vapor Deposition Lab-grown diamonds are cultivated in laboratories using two growth methods - HPHT and CVD. In this article, we won’t focus directly on the growth methods themselves, but rather on what should matter to you as a customer when choosing a lab-grown diamond and why. This is our subjective opinion based on our experience. CVD Method We recommend choosing the CVD method for smaller stones that are not certified (IGI, GIA). Lab-grown diamonds produced using the CVD growth method are detected as "diamond" on testers, while small HPHT stones are detected as "moissanite." It can then be challenging to prove whether the stones are moissanites (SiC - silicon carbide) or lab-grown diamonds. The set stone would have to be removed from the jewelry, which is, of course, an unwanted intervention that could destroy the already made piece. On the other hand, it is essential to be cautious and request confirmation from sellers of natural diamonds that the set diamonds are not lab-grown. Lab-grown diamonds are indistinguishable from natural ones, and if they are already set in jewelry, the customer has no way to differentiate them. You can’t tell the difference between natural and lab-grown diamonds even when they’re not set in jewelry, so it relies on the manufacturer’s trustworthiness regarding the diamonds they use. The only difference between small natural and lab-grown diamonds is the price. Small natural diamonds do not have certification or markings on the girdle, which all larger certified lab-grown diamonds have. HPHT Method For larger certified lab-grown diamonds, on the other hand, we recommend choosing the HPHT growth method. From our perspective, these are lab-grown diamonds that achieve higher quality compared to lab-grown diamonds produced by the CVD method. CVD lab-grown diamonds often achieve a lower color grade (G-H) and are then "enhanced" by using the HPHT method by one or two grades – a G-H lab-grown diamond produced by the CVD method can be improved to a higher color grade through the HPHT process. Additionally, HPHT is a method that closely mimics the conditions under which natural diamonds form deep underground. However, what can be confusing is that lab-grown diamonds produced using the HPHT method can be detected as "Moissanite" on testers. This is due to the presence of tiny metallic particles that affect the testers. On the other hand, these lab-grown diamonds have a unique number on the girdle that matches the certificate number you receive with the lab-grown diamond. Customers can then quickly and easily verify information about the color, clarity, cut, and other properties either directly from the certificate or on the IGI website (Verify Your Report - IGI). Here, you can also download the certificate in PDF format at any time. The certificate also states whether the stone may contain additional treatments (in the case of the CVD method) or that it contains no additional treatments (HPHT). This information is listed at the bottom under the basic information about the lab-grown diamond. Summary: For small uncertified stones, we recommend the CVD method. For larger certified stones, we recommend HPHT lab-grown diamonds
