1.70 ct Natural Unheated Green Sapphire

A natural 1.70 carat light green sapphire, completely unheated. Light green sapphire is the softer, lower-saturation end of the green corundum range — a tone that reads with a quiet, airy freshness rather than the bold presence of vivid or deep green. At 1.70 carats unheated, this stone has sufficient weight for center stone applications, and the light saturation creates a soft, delicate character that pairs naturally with pale settings and minimalist design.

Rarity Analysis

A few factors are worth weighing honestly when considering how this stone fits into the broader sapphire market:

• Green is a Less Common Commercial Color: Blue and pink/padparadscha tones dominate the sapphire market; green sapphire in general sees far less commercial supply and demand, which gives it a distinct position rather than a mainstream one.
• Unheated Status is a Real Factor: The large majority of sapphire on the market today is heat-treated to improve color and clarity. A genuinely unheated stone, disclosed as such, is a meaningfully smaller subset of available material.
• Light Saturation is a Character, Not a Rarity Claim: The soft, low-saturation tone of this stone is an aesthetic choice, not evidence of greater scarcity — deep or vivid green sapphire is not less available because it's more saturated, and this lighter tone shouldn't be marketed as rarer than it is.
• Clarity is Ordinary for the Category: This stone is Slightly Included — our own assessment, not a lab grade — minor inclusions visible under magnification. That is typical for natural untreated sapphire and is not a scarcity factor either way.
• Documentation: Weight, dimensions, round shape, green color and the absence of heating are recorded on AGCL Report #M260346. Origin is our own assessment — the AGCL report does not address geographic origin, so Madagascar is a seller representation rather than an independently verified finding.
• Combined Value: Together, the unheated status and the green color category give this stone real, honest value — without needing to lean on clarity, documentation depth, or a lab-verified origin it doesn't have.

Buying Guidance

• Verify Unheated Status Independently: If treatment history matters to your purchase, ask for or request a lab report confirming unheated status before buying.
• Ask Us About Anything Not Documented: The shape, cut, dimensions, treatment and lab report are all listed below. Origin is our own assessment rather than a lab finding — if that distinction matters to your purchase, reach out and we'll be clear about exactly what is and isn't documented.
• View Against Different Backdrops: Light green sapphire reads differently depending on background and setting metal — it can look fresher against white metals and warmer against yellow gold. Viewing the stone against a few different backdrops before deciding will give you a truer sense of how it will look in your setting.
• Consider the Aesthetic, Not Just the Specs: This is a soft, quiet color position rather than a bold one — make sure that's the look you want before committing.
• Try Before You Buy: Where possible, view the stone in hand (or ask for additional photos/video in different lighting) before finalizing your purchase.
