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.

Good to Know

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.
• Ask for a personal video if you would like to see the stone in motion before finalizing the purchase.
