Lacy and geometric with a filigree bar and W-shaped detail in the setting, the Kobelli Solitaire W Head Ring offers an icon of old and new. Tradition in the subtle curves tucks under the center; modern design incorporates W shapes to the prong setting. At Kobelli, social responsibility and genuine authenticity is at the core of every piece. The bridge hoists the 6.5mm round moissanite in solid 14-karat gold. Four double prongs secure the stone in place with a W-shaped profile where the head joins on both sides of the engagement ring. The ring in the photos is a size 5.
