Splendid Seven-Diamond Riviera/Veretta Ring This magnificent ‘veretta’ (or Riviera) ring model with seven stones is a triumph of light and timeless elegance. Ideal for celebrating an important anniversary or an unforgettable milestone, the timeless design maximizes the brilliance of the gems, creating a continuous ribbon of light around the finger. It showcases high‑jewelry craftsmanship. The solid white‑metal setting (likely 18k white gold or platinum) uses a raised U‑shaped prong setting. This architectural technique leaves the diamond sides free, allowing light to pass through the stones from every angle and maximizing their fire and brilliance. Inside the shank there are also elegant factory engravings and the hallmarks that attest to authenticity. Technical Details and Carat Calculation To calculate the total carat weight, we base it on the diameter of the stones. A round brilliant-cut diamond with a diameter of 4 mm has an estimated standard weight of about 0.24–0.25 carats. Multiplying this value by the number of gems (7) yields: 0.25 ct × 7 stones = 1.75 total carats (estimated). Here is the summarized technical sheet: Type: Seven‑stone Veretta / Riviera ring. Gems: 7 natural round brilliant-cut diamonds. Stone Size: 4 millimeters in diameter for each gem. Estimated Total Carat Weight: ~1.75 ct overall. Total Jewelry Weight: 5.4 grams (a substantial weight that lends solidity and prestige to the setting). Finger Size: 13 (Italian standard size). Setting Style: Shared prongs, designed to enhance luminosity. This ring is a true “statement piece”: the generous size of the 4 mm diamonds combined with the 5.4-gram weight makes it a jewel of absolute prestige, with a bold and luxurious presence, yet always refined.
