1.04 ct Natural Heated Blue Sapphire – Marquise Cut | Sri Lanka (Ceylon)

A natural 1.04 carat blue sapphire in a marquise cut, from Sri Lanka (Ceylon), heat treated. Marquise-cut blue sapphire is an unusual combination — the pointed-oval outline is rare in colored stones because the two sharp tips are structurally vulnerable and lose weight relative to oval or cushion cuts. When well-executed, however, a marquise is the format that elongates the finger most dramatically of any cut shape, and the elongated face-up footprint makes the stone read significantly larger than its carat weight suggests.

Rarity Analysis

Blue is the most common sapphire color overall, but marquise is one of the least common cuts applied to blue sapphire because the pointed ends sacrifice rough yield that ovals and cushions preserve.

• Color: Medium-intense, saturated blue with no significant gray modifier — a solidly desirable tone, though not at the rarest "royal blue" hue position.
• Size: 1.04 ct is a practical center-stone weight, but marquise cutting typically yields smaller finished stones from the same rough than round or oval cuts — 1+ carat marquise blue sapphire is less commonly seen than 1+ carat oval.
• Treatment: Heat treatment is standard and disclosed for this stone, consistent with the overwhelming majority of commercial blue sapphire.
• Cut: The marquise shape itself is the standout rarity factor here — most cutters favor oval or cushion for blue sapphire rough to maximize both weight retention and market demand.
• Documentation: Certification and report details were not provided in this stone's product data; buyers should request current lab documentation if certification matters to their purchase.
• Combined effect: It's the uncommon pairing of a genuine marquise cut with even, medium-intense Ceylon blue at just over 1 carat — not the color alone — that makes this stone hard to source as a direct match.

Buying Guidance

A few practical points to weigh before purchasing this specific stone:

• Check the tips carefully before setting. Because marquise sapphires have two pointed ends, view the stone in person or via video to confirm symmetry and that there's no chipping at the points.
• Plan for V-tip prong protection. A marquise this size needs V-tip prongs to protect the pointed ends — factor that into your setting choice.
• Ask about certification directly. A lab report wasn't included in this listing's product data — if third-party documentation matters to you, request it before purchase.
• Weigh availability of this cut and size together. Marquise-cut blue sapphire above 1 carat is uncommon relative to oval or cushion cuts of the same weight, which affects both sourcing and price when comparison shopping.
• Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.

Why Choose this 1.04 ct Marquise Ceylon Blue Sapphire?

The marquise shape in blue sapphire at just over 1 carat gives strong visual impact without the weight of a 1.5+ carat oval. The elongated outline reads larger face-up than a round or cushion of the same weight, and in a solitaire ring setting it creates the finger-elongating effect that makes marquise the preferred choice for certain engagement aesthetics. Ceylon origin adds the provenance and color quality that defines fine blue sapphire.
