Frequently asked questions
Is the diamond real? Yes, it is a lab-grown diamond: the same physical, optical and chemical properties as a mined diamond, produced with CVD / HPHT technology.
Is it certified? Yes, every ring includes a laboratory certificate (IGI).
Which gold is used? 18 kt / 750 gold, available in white, yellow or rose. The colour of the metal does not affect the price.
How do I choose the size? The reference measurement is the inner circumference in mm; conversions and instructions are in the Size guide.
The images are renderings faithful to the real specifications of the piece. The images show the 3 ct version; other carat weights appear proportionally smaller or larger. Other carat weights can be requested by writing to us.
Each AREPO piece is made to order. This keeps the collection essential and lets us check every jewel before it reaches you.
Allow roughly 2–3 weeks from order to delivery: after crafting, every piece passes a second quality control in Switzerland, then AREPO packaging and tracked shipping. Selected best-sellers may be kept in stock in Switzerland for faster dispatch.
Diamonds are accompanied by an IGI certificate. IGI is the world's leading laboratory for lab-grown diamonds; every report carries a unique number you can verify on igi.org.
The certificate states the 4Cs — cut, colour, clarity and carat — and confirms that the diamond is lab-grown.
