What Makes This Gemstone Special?

Color: This ruby displays a vibrant, fiery red tone—achieved through a traditional enhancement process that brings out the natural beauty of corundum with a faint red tint. The result is a rich, consistent color that evokes emotion and elegance.

Clarity & Character: Like all genuine rubies, this gemstone features natural inclusions, which give it a unique fingerprint and inner life. These characteristics are preserved and enhanced through a careful heat-and-oil treatment process.

Cut: Expertly faceted to highlight its depth and brilliance, maximizing the gem's light reflection and overall appeal.

About the Treatment

This gemstone has undergone a color enhancement process that combines heat and oil infusion, commonly used in Rajasthan, India. During this process, natural corundum with faint red tones is gently treated to enrich its color through absorption into surface-reaching fractures. While some of industry may categorize this under “dye-treated” or “color-infused corundum,” it's important to clarify: This is not a synthetic ruby. This is not a glass-filled or imitation stone. The base material is genuine corundum naturally formed with light red tint to sometimes colorless while having natural inclusions same as all the corundum family has. The enhancement process is similar in principle to those used for emeralds and rubies worldwide and is aimed at improving appearance.

Why Choose This Stone?

Striking Appearance at Great Value: Enjoy the rich look of a ruby without the premium price of untreated stones.

Ethical Transparency. Wonderful for jewelry setting. Perfect for mass producing Jewelry factories!!

Durability & Design Flexibility: With a Mohs hardness of 9, this stone is suitable for rings, pendants, and everyday wear and the color doesn’t come off.

Final Note —

This gemstone is part of a long-standing tradition in Rajasthan, India, where skilled artisans enhance naturally mined corundum to create accessible, beautiful stones with a ruby-like appearance. We are proud to offer these responsibly sourced and expertly treated gems to customers who value beauty and often are called Joban Rubies in Rajasthan, India and used in jewelries for decades.

Add a piece of timeless, fiery elegance to your collection today.

Automatic Bid

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.
