Diamonfire Jewellery Guide
Diamonfire delivers the brilliance of diamonds without the prohibitive cost. Each piece features zirconia stones cut to 57 facets — the exact geometry of an ideal-cut diamond — laser-engraved for authenticity, and set in 925 sterling silver with triple precious metal plating.
At OD’s Jewellers, Diamonfire is the affordable fine jewellery alternative — combining brilliance, durability, and craftsmanship that rivals far higher-priced brands.

What Makes Diamonfire Different
57-Facet Ideal Cut
Each stone cut within the tolerance range of diamonds with 57 hand-polished facets. Light dispersion equal to that of a natural brilliant.
Triple Plating
Three-layer protection: rhodium, palladium, and platinum for silver-tone; 24ct gold for gold-tone. Exceptional tarnish resistance.
Laser Authentication
Every stone laser-engraved with the Diamonfire logo — permanent verification invisible to the naked eye, visible under magnification.
Family Heritage
Founded 1973 by Burkhard Müller in Rülzheim, Germany. Now second-generation family-managed with daughters Claudia and Anna-Maria.

3 | Craftsmanship & Innovation
The Ideal Cut Process
- 57 hand-polished facets matching brilliant-cut diamond geometry
- Cut within the tolerance range of diamonds
- Measured using diamond grading criteria (purity, proportion, colour)
- Estimated in carat equivalents
- Laser-engraved with Diamonfire logo for authenticity
Triple Plating System
Why Triple Plating Matters
Standard single-layer plating wears quickly. Diamonfire’s three-layer system (rhodium, palladium, platinum) provides exceptional durability and preserves brilliance far longer than standard plated jewellery. Gold-tone pieces use 24ct gold plating.
Presentation
Every piece arrives in a luxurious velvet-lined silk box with coordinating gift bag and certificate of authenticity confirming carat equivalent and quality specifications.
