The gold plate reflects light in the same way as the diamond facets, creating a combined light-return effect that reads as a larger stone than 0.15ct in a conventional setting.

An \u003cstrong\u003eillusion diamond necklace\u003c\/strong\u003e at 0.15ct solves this: the mirror-polished gold plate surrounding the stone extends the visible light-catching surface area, making the pendant read as a substantially more prominent piece at the neckline.\u003c\/p\u003e\u003ch2\u003eRound Brilliant — Illusion Setting at 0.15ct\u003c\/h2\u003e\u003cp\u003eThe Round Brilliant cut at 0.15ct returns the maximum proportion of light for its crown diameter. In an illusion setting, this optimised light return combines with the reflective gold plate to create a unified light-catching effect. The result is a pendant that reads as more significant than a solitaire at the same carat weight.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eHow does an illusion setting make a diamond look larger?\u003c\/h3\u003e\u003cp\u003eAn illusion setting uses a mirror-polished gold plate beneath and around the diamond. The polished gold surface reflects incoming light in the same way as the diamond facets — from a normal viewing distance, the eye cannot distinguish the gold reflections from the diamond reflections. The visual result is a stone that appears larger than its actual carat weight.\u003c\/p\u003e\u003ch3\u003eIs 0.15ct a real diamond in an illusion pendant?\u003c\/h3\u003e\u003cp\u003eYes — the diamond in an illusion setting is a real natural or lab-grown stone. The illusion technique applies to the setting, not the stone. The diamond is set in a mirror-polished gold plate that amplifies its apparent size; the stone itself is unchanged.\u003c\/p\u003e\u003ch3\u003eWhat chain length works with an illusion pendant?\u003c\/h3\u003e\u003cp\u003eA 16 or 18 inch chain positions the pendant at the collarbone, which is the standard position for a pendant of this size. The solid gold chain and bail are included and proportioned for the pendant.\u003c\/p\u003e","brand":"Qutahia Jewellery","offers":[{"title":"Yellow Gold \/ 14ct \/
