About Luc Yen:
Nestled in the mountainous regions of northern Vietnam, Luc Yen has gained global prestige among gem dealers and collectors for its ethically sourced, naturally vibrant rubies. Unlike mass-produced stones, Luc Yen rubies are often hand-mined by local communities, resulting in gems that carry not just beauty, but authenticity and provenance.

Unheated rubies of this size and origin are becoming increasingly rare in the global market, making this piece a worthy addition for serious collectors, bespoke jewelry designers, or investors in fine gemstones.

Why are users outbidding themselves?
When a bid is placed, this is the maximum amount a person is willing to bid for the product. Our system will then automatically bid on behalf of the bidder, incrementally increasing the bid up to the maximum to maintain their position as the highest bidder.
When there is an icon indicating 'Automatic Bid', it means our system is actively placing bids for the bidder based on their maximum bid. This may appear as if bidders are outbidding themselves, but it's simply a result of the system updating the bid to reflect the bidders maximum limit.
