It is the same construction across this family of rings, and the reason the stone reads first and the setting second.

That hardness is the practical argument for a sapphire engagement ring: it takes daily wear better than almost anything else. Our \u003ca href=\"https:\/\/aquamarise.com\/blogs\/journal\/sapphire-engagement-rings\"\u003ecomplete guide to sapphire engagement rings\u003c\/a\u003e covers the wider case.\u003c\/p\u003e\n\u003cp\u003eThis stone is lab-grown, which means identical chemistry and hardness to mined corundum with a saturated violet-purple that would be scarce and expensive in nature. The center measures 6 × 8 mm and is set north–south so its length runs along the finger — the most elongating orientation, as our \u003ca href=\"https:\/\/aquamarise.com\/blogs\/journal\/marquise-engagement-rings-the-most-elongating-shape\"\u003eguide to marquise engagement rings\u003c\/a\u003e sets out.\u003c\/p\u003e\n\u003cp\u003eThe cut is what sets it apart. Rather than the standard brilliant faceting, the crown is carved as a fantasy cut — concave facets radiating from a single point so light breaks into a starburst across the face of the stone. It is a labor-intensive style, rarely seen at this size, and it gives the stone a sense of internal movement as the hand turns.\u003c\/p\u003e\n\u003ch2\u003eMetal and Stones\u003c\/h2\u003e\n\u003cp\u003eThe ring is solid 925 sterling silver throughout, finished in \u003ca href=\"https:\/\/aquamarise.com\/blogs\/journal\/what-is-black-ruthenium\"\u003eblack ruthenium\u003c\/a\u003e — a platinum-group metal that settles to a deep gunmetal rather than a flat black, holding just enough reflectivity for the leaf veining to read as texture.\u003c\/p\u003e\n\u003cp\u003eThe two marquise side stones are lab-grown purple sapphire in a lighter, cooler violet, chosen to step down in tone from the center rather than match it. The twelve white accents — ten heart cut across the shoulders, two round brilliant at the points of the center stone — are cubic zirconia.
