Answers to the questions we hear most about 925 sterling silver, lab-grown diamonds and shopping with us.
925 sterling silver
What is 925 silver?
925 sterling silver is 92.5% pure silver and 7.5% copper. The copper gives the silver strength so it holds its shape for everyday wear.
Does silver jewellery tarnish?
Silver can darken over time, especially in humid weather. Regular cleaning brings the shine back. See our care guide.
Can I get my jewellery engraved?
Yes. Engraving is available on most pieces.
How do I find my ring size?
Use our ring size guide to measure at home, or get measured in-store at Banani.
Lab-grown diamonds
Is a lab-grown diamond a real diamond?
Yes. A lab-grown diamond is chemically, physically and optically identical to a mined diamond. Only its origin is different.
How is a lab-grown diamond different from moissanite?
Moissanite is a different mineral (silicon carbide) with a rainbow-like sparkle. A lab-grown diamond is diamond, with the same hardness and fire as a mined one.
Does it come with a certificate?
Yes. Every lab-grown diamond comes with its own certificate.
What metal are the lab-grown pieces set in?
Our current lab-grown diamond pieces are set in 925 sterling silver.
