1.75 ct Natural Heat-Treated Blue Sapphire – Round Cut | GIA Certified | Sri Lanka (Ceylon)

A natural 1.75 ct Round Cut Blue Sapphire from Sri Lanka (Ceylon), heat treated, accompanied by GIA Report #2243032036. This stone's dimensions (6.57 - 6.78 x 5.07mm) place it as a well-proportioned round brilliant that reads full face-up, with the classic Ceylon medium-intense blue that has anchored the sapphire trade for centuries. The GIA report confirms the Ceylon origin, weight, dimensions, and treatment status, giving buyers independent documentation behind every claim on this listing.

Rarity Analysis

This is a classic, well-executed Ceylon blue sapphire — GIA-documented and heat treated to the accepted industry standard. It is not a one-in-a-thousand phenomenon stone, and we won't describe it as one. What it does offer are real, verifiable differentiators worth understanding before you compare it to other listings:

• Ceylon Origin, GIA-Confirmed
  Sri Lanka has been the benchmark source for fine blue sapphire for over 2,000 years, and GIA Report #2243032036 independently confirms this stone's Ceylon origin rather than relying on seller claims alone.
• Round Brilliant in a Colored Stone
  Round is the most demanding cut to execute well in sapphire, since it sacrifices carat weight to maximize brilliance and even color return — most Ceylon rough is cut into ovals and cushions instead.
• Eye-Clean Clarity
  GIA grades this stone Eye Clean, meaning no inclusions are visible to the unaided eye — a meaningful quality threshold, not every heat-treated Ceylon sapphire on the market clears it.
• Fully Disclosed, Stable Treatment
  Heat treatment here is standard, permanent, and disclosed on the GIA report itself — there is no ambiguity about what has or hasn't been done to this stone.
• Documented, Not Just Described
  Every specification on this page — weight, dimensions, origin, treatment — is independently verifiable against GIA Report #2243032036, not just a seller's word.

Buying Guidance

A few practical points to weigh before buying this stone, or any round-cut Ceylon blue sapphire in this size range:

• Confirm the Lab Report Matches the Stone
  Always check that the GIA report number (2243032036) and its stated measurements match the physical stone before you buy — we encourage you to review the report alongside the listing.
• Heat Treatment Is the Market Norm
  The vast majority of commercially available blue sapphire is heat treated; this is standard practice and does not diminish value when properly disclosed, as it is here.
• Round Cuts Favor Certain Settings
  A round brilliant sapphire works well in solitaire, halo, and three-stone settings; if you have a specific ring style in mind, confirm the 6.57–6.78mm diameter suits your setting's head size.
• Compare Price Per Carat, Not Just Total Price
  At $2,816.00 for 1.75 ct, this stone runs roughly $1,609.14 per carat — a useful figure to benchmark against other GIA-certified Ceylon sapphires of comparable size and clarity.
• Ask About Setting Compatibility
  If this stone is destined for an engagement ring, discuss prong height and metal choice with your jeweler before setting — Mohs 9 hardness makes it durable, but proportions still matter for security.
