The Art of Weight & Hallmark: Three Solid 18-Karat Gold Masterworks
Unlike plated or hollow imitations, a true High Jewelry timepiece commands between 186.5 and 282.4 grams on the balance. Inspect our three flagship Place Vendome vitrines below.
Rolex Day-Date 40 60th Anniversary Olive Green Dial 18K Everose Gold Reference 228235 — Hallmarked Edition

Metallurgical Density: Why Solid 18K Gold Cannot Be Faked on the Scale
In Place Vendome and Geneva salons, the first test of authenticity is gravimetric mass. Pure 24K gold has a density of 19.32 g/cm³, creating an 18K alloy density of 15.5 g/cm³—nearly double that of 316L/904L steel. Every creation in our archive is weighed on 4K video before your insured armored shipment is released.
