At 1.10 carats, this round sapphire crosses the 1-carat threshold that makes it practical as a center stone in engagement rings and pendant solitaires — a weight with sufficient face-up surface to display blue sapphire's color at wearing distance. The round brilliant cut returns the highest light of any shape, making the blue vivid and active under any lighting condition.\u003c\/p\u003e\u003cdiv style=\"border: 2px solid #5b2c6f; border-radius: 10px; padding: 20px 24px; margin: 28px 0; background-color: #f9f5fc;\"\u003e\n\u003ch2 style=\"color: #4a235a;\"\u003e\u003cspan role=\"text\"\u003e\u003cstrong\u003eExpert Opinion\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003e\"Round blue sapphire just above the one-carat mark is one of the most dependable specifications we carry. It's the shape and weight combination that fits off-the-shelf settings without custom work, and at 1.10 carats it still reads as a genuine center stone rather than an accent.
