About the price index Bague Marquise Yvonne Léon
The **Marquise Ring** by **Yvonne Léon** is part of the house's signature aesthetic: a contemporary jewellery piece with graphic lines, inspired by vintage codes and designed to be worn daily as well as a statement piece. Its immediately recognisable marquise silhouette often showcases coloured stones, diamonds, or combinations of yellow, white, or rose gold, which enhances its appeal on the pre-owned market. Its resale interest stems from the brand's growing notoriety, the clarity of the design, and sustained demand for identifiable rings that are easy to wear and collect. The value varies greatly depending on the condition, the presence of the case or certificate, the size, the rarity of the reference, as well as the type of materials and stones. Versions in excellent condition, lightly worn, or from a sought-after series, trade significantly above more common models.

Reading the Bague Marquise Yvonne Léon price guide
The range observed for Bague Marquise Yvonne Léon runs from €1,000 to €12,000, with a median of €4,500 — a 12× gap between entry-level examples and the most sought-after ones. That spread is normal: on this model, condition, material and year weigh more heavily than the reference itself.
In practice, a piece below the median usually shows accepted signs of wear or a common configuration; above it you find rare colours, precious hardware and complete sets with the original box and invoice.
What pushes the Bague Marquise price guide up
- Gemmological certificate and perfectly legible hallmarks
- Original stones, setting never reworked
- Box, warranty and invoice from the maison
- Identifiable collection, still catalogued or archived
Selling a Bague Marquise Yvonne Léon at the right price
We offer two options on this model. Outright purchase, settled within 72h once the piece is authenticated, suits anyone who wants an immediate exit. Consignment aims for the top of the range: the piece is photographed, promoted and sold with a commission that decreases with your membership card.
Signed jewellery keeps a floor value tied to metal weight and stone quality; the maison's signature and the presence of the certificate add the decisive resale premium.
