Square Pink Tourmaline & Diamond Halo Necklace

A 4 by 4 mm square-cut natural pink tourmaline held in claw prongs (Stuller specifies a three-prong claw mount), inside a continuous diamond halo whose outer edge is softened to a cushion. Square stone, rounded halo: the contrast between the two outlines is what gives a 7.76 mm pendant more presence than its size suggests.

A square cut sends light back in four broad quadrants rather than scattering it, so the colour stays even across the table. The halo of natural diamonds supplies the sparkle around the edge that the cut itself does not.

Choose 16 inch or 18 inch. Each length is its own finished necklace on a solid gold cable chain, so you are buying the length you pick.

The cornered halo is the dressier cousin of a plain solitaire: a first anniversary, a graduation, a piece bought to mark something specific.

The pink tourmaline is natural. Where the design carries diamonds, the accent diamonds are natural too, never lab-grown or simulated, and are supplied to a published colour and clarity spec.

Gemstone and diamond carat weights are nominal totals and are approximate; actual weight may vary slightly from the stated figure. Millimetre measurements are nominal and vary piece to piece within normal manufacturing tolerance.
