Quality & Certification

Every Lana & Lona jewelry piece is crafted in accordance with Ukrainian state standards and undergoes official quality control. We use only precious metals and gemstones and guarantee the authenticity of every piece we create.

Official Quality Control

Each piece bears:

— an official state hallmark, confirming the purity of the precious metal (585 or 750);

— the manufacturer’s registered mark, officially issued by the Ministry of Finance of Ukraine, confirming our registered production and the brand’s legitimate operations.

All Lana & Lona jewelry undergoes official state assay control, and our studio operates in full compliance with Ukrainian legislation.

Diamond Certification

For jewelry featuring diamonds, we provide certificates confirming their origin and key characteristics.

International certificates are provided by:

— GIA — for natural diamonds from 0.25 ct;

— IGI — for laboratory-grown diamonds from 0.30 ct.

For other diamond jewelry, a quality certificate or gemological report is provided depending on the type and characteristics of the gemstone.

What the Certificate Confirms

A diamond certificate provides an independent assessment of the stone and confirms:

— authenticity;

— carat weight;

— color;

— clarity;

— cut quality;

— other key characteristics that determine its quality and value.
