Frequently asked questions & answers

How do I best care for my Infina ring?
To preserve the beauty of your Infina ring, we recommend cleaning it regularly with a soft cloth and avoiding contact with strong chemicals. Store it in a jewelry box when not in use.
All our rings are made from 100% recycled gold. You can choose between yellow gold and white gold, in the caratage that suits you best. 18 carat gold offers a rich, deep tone with a high gold content, while 14 carat gold offers a slightly lighter shade with extra durability for everyday wear. White gold is always delivered with rhodium plating for a clear, white finish that highlights the diamond's brilliance. If you are unsure which metal is best for you, you can read more in our metal guide.
At Coliène, you can freely choose between natural and lab-grown diamonds. Both are real diamonds with identical chemical composition, hardness, and brilliance—the difference lies in how they were created. Natural diamonds have been formed over millions of years deep within the earth, while lab-grown diamonds are created in a controlled environment with the same result. All diamonds we offer are conflict-free and certified. Lab-grown diamonds often offer a lower price for the same size and quality. If you want to know more about the four Cs and what determines a diamond's quality, we recommend our diamond guide.
The shank is the band of the ring — the part that encircles the finger and gives the ring its shape and character. We offer shanks in several outer profiles, from classic round to straight and modern.
The width affects the expression: a narrower shank gives a delicate and feminine impression, while a wider shank has more presence. All our shanks have a rounded or domed interior for maximum comfort throughout the day.
If you want to understand more about profiles, widths, and profile height, our shank guide is available.
Ring size indicates the inner circumference of the ring in millimeters — the system we at Coliène use. The most common women's sizes are between 48 and 54, and the most common men's sizes are between 60 and 66. If you are unsure of your size, we recommend ordering a free ring sizer that will be sent to your home. You can also use a ring you already own and measure it using our size guide. If the size is incorrect, we offer a free resizing service.
Personalize your ring with an engraving on the inside of the band. You can choose text, a date, initials, or a symbol — entirely according to your wishes. Engraving is included free of charge on all our rings and is done by hand with care. The text is discreetly placed on the inside and does not affect the ring's fit or appearance. If you order a ring with engraving, please note that the delivery time may be extended by a few extra business days.
