Carateu was founded to make buying certified diamonds and fine jewelry feel clearer, calmer and more trustworthy for European buyers.
After years working in technology and finance, founder Raiha Buchanan left the fintech industry to study gemology in Surat, India, one of the world’s most important diamond hubs. Today, every certified diamond is independently reviewed in Stockholm before dispatch, combining gemological expertise with a more personal approach to guidance and service.

Common Questions
Is it safe to buy diamonds online in Europe?
Yes, buying diamonds online in Europe can be safe when you choose a seller that offers independent certification, transparent pricing, and EU-based fulfilment. At Carateu, all diamonds are graded by recognised laboratories such as IGI or GIA and are verified by our team before being shipped from Sweden. This ensures both quality and compliance with EU consumer protection laws.
Are there any extra import fees or duties I need to pay when buying from Carateu?
No. All diamonds from Carateu are shipped from within the EU. This means VAT is handled correctly from the outset and no import fees apply after purchase.
The price you see includes VAT, and you always pay the full amount at checkout with no unexpected customs or administrative charges.
What is the difference between lab grown diamonds and natural diamonds?
Natural and lab-grown diamonds are both real diamonds with the same physical, chemical, and optical properties. The difference lies in how they are formed: natural diamonds are created in the earth over millions of years, while lab-grown diamonds are produced in controlled environments using advanced technology.
At Carateu, it is always clearly stated whether a diamond is natural or lab-grown, so you can choose based on your preferences, budget, and values.
Which diamond certifications does Carateu offer on its diamonds?
Carateu works exclusively with diamonds certified by the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). These independent laboratories are internationally recognised and grade a diamond’s cut, colour, clarity, and carat weight according to established standards.
Are all purchases final?
Some products may be marked as final sale and are not eligible for return. This will always be clearly stated before purchase, so you know what applies before completing your order.
Where do Carateu’s diamonds come from, and how are they verified?
Carateu sources diamonds globally from trusted suppliers. Each diamond is independently certified and verified by either IGI or GIA, before being shipped from Sweden to customers within the EU.
