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.
• Eye-Clean Clarity: No visible inclusions under normal viewing conditions, which is a favorable but not unusual clarity grade for sapphire.
• What This Listing Doesn't Specify: This listing does not state a cut/shape, an origin, or a certifying lab and report number. That's simply how this stone is currently documented, and we'd rather say so plainly than talk around it.
• Combined Value: Together, the unheated status, the green color category, and eye-clean clarity give this stone real, honest value — without needing to lean on documentation depth or origin claims 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 Directly About Cut, Origin, or Certification: This listing doesn't specify a shape/cut, an origin, or a certifying lab. If any of those details matter to you, reach out to us directly — we're happy to answer what we can and be clear about what 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.
