0.45 CT DIAMOND SOLITAIRE RING

The clean lines of this solitaire

Modern solitaires often favour clean lines and unadorned geometry. This second-hand ring embodies this approach through its simplicity. At its centre sits a natural brilliant-cut diamond, estimated at 0.45 carats. Its clarity and even cut reflect light directly. The setting is crafted from solid 18K white gold, offering a cool, dense and timeless aesthetic.

Architecture and jewellery craftsmanship

The structure is distinguished by its substantial volume. The body of the ring forms a thick metal band with sharp edges. This heavy base contrasts with the open setting of the stone. The diamond is held in place by four straight, smooth prongs. This openwork design elevates the stone and allows light to penetrate the culet from multiple angles. The flat sides and even polish are testament to precise technical craftsmanship.

Why choose this second-hand solitaire ring

Purchasing a setting of this calibre second-hand is a practical choice. Standard contemporary designs often use less gold to optimise costs. This volume of material provides a stable fit on the finger and ensures high resistance to everyday wear and tear. The combination of a 0.45-carat diamond with this robust structure results in a piece that emphasises its physical and material value.

Contents and condition

This piece is available in size 50. The inside of the ring is engraved with ‘750’, confirming the alloy’s fineness, as well as a master’s hallmark. Our workshops have carried out a full polish followed by rhodium plating to ensure a uniform grey colour. The tension of the four prongs has been checked to ensure the stone is securely held. The ring is delivered in a The Swiss Collector presentation box.
