Materials & FAQ
Every POLKI diamond piece is created with integrity — combining advanced innovation with the timeless art of fine jewellery.
Our lab-grown diamonds are real diamonds, identical in composition, brilliance, and durability to those mined from the earth. Each stone is cultivated under controlled laboratory conditions using sustainable methods that mirror the natural process of diamond formation.
This commitment allows us to offer true beauty — responsibility and transparently.
Every POLKI diamond above 0.3 carats is accompanied by an independent gemological certificate, issued by leading institutions such as the International Gemological Institute (IGI) or the Gemological Institute of America (GIA).
The certificate includes detailed analysis of the diamond's:
Carat weight
Color
Clarity
Cut
Growth method and unique identification number
Each certificate corresponds to the exact diamond set in your piece and can be verified through the issuing institute's online database.
All POLKI creations are crafted in either 18K or 14K gold and stamped accordingly to indicate purity. Each finished piece is carefully inspected to ensure it meets international standards for fine jewellery craftsmanship and hallmarking.
POLKI ensures full transparency for every material used:
Moissanite stones are sourced for their superior brilliance and clarity.
Freshwater and mother-of-pearl elements are genuine and individually selected for luster and tone.
Stainless-steel designs are made with premium-grade steel, chosen for durability and refined finish.
Each piece is an authentic expression of the brand’s philosophy — honest materials, enduring craftsmanship, and conscious beauty.
Your certificate of authenticity will be enclosed with your order where applicable.
For bespoke creations, a digital record of gem origin and material specification will be archived within POLKI's internal registry for verification upon request.
At POLKI, authenticity is not a label — it is a principle.
Every creation represents a union of artistry, science, and sincerity, ensuring that the beauty you wear is as genuine as the story behind it.
