A Rare Untreated Color Change Sapphire of Exceptional Brilliance

This 1.57 carat natural color change sapphire is a true collector’s gemstone — a rare no-heat specimen with a beautifully sharp octagon cut and remarkable brilliance. Certified by AIG, this sapphire displays a vivid and dynamic shift in color, revealing two distinct personalities depending on the lighting.

Untreated color-change sapphires of this quality are highly sought after, and examples with this clarity and fire are becoming increasingly difficult to find.

Color: A Dynamic Transformation of Hue & Light

This gemstone reveals a vibrant, lively color shift, showcasing one rich hue in daylight and transforming into another expressive tone under warm indoor lighting.

Its color change is:

  • Strong and noticeable

  • Cleanly distributed across the gem

  • Enhanced by its high clarity and balanced saturation

This dual-hue behavior gives the sapphire a magical, ever-changing character—like owning two gemstones in one.

Cut & Brilliance: Octagon Precision

The octagon cut has been expertly executed to:

  • Maximize brilliance

  • Sharpen the color shift

  • Produce crisp internal reflections

  • Enhance the face-up presence

Each facet works in harmony with the color-change effect, creating a gemstone that glows and comes alive with every movement.

Why This Sapphire Is Exceptional

  • AIG Certified (No Heat): Fully natural color, untouched and unenhanced — extremely desirable among collectors

  • Strong Color Change: A vivid, lively shift that greatly increases rarity and value

  • Superb Clarity: Clean internal appearance allows both hues to shine brightly

  • Octagon Cutting: Elegant shape that enhances both brilliance and color distribution

  • Durability: Mohs hardness 9 — perfect for jewelry of all types

At Drewelryshop, we curate gemstones that offer both visual elegance and true rarity. This 1.57 carat no-heat color-change sapphire stands out as a gem with exceptional personality and collectible value.

A treasure for connoisseurs and lovers of unique gems — available exclusively at Drewelryshop.

Why are users outbidding themselves?

Automatic Bid icon
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.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
