{"type":"firestarter.listing","listing":{"id":"lst_Vvx4eOVX","product_name":"1.5ct Marquise Lab Diamond Three Stone Ring","category":"Rings","description":"The marquise shape is a timeless and elegant cut that shows off how a lab diamond really sparkles. The marquise center stone is set with petal prongs and is accented by two pear-shaped lab diamonds to create a three-stone motif and an open marquise design on each side of the band. A gorgeous engagement or statement ring.\nThe filigree pattern does not go completely around the chevron band, to make resizing and engraving possible.\nStyle tip: This ring pairs perfectly with our Open Filigree Chevron Diamond Band.\nRing comes with an Automic Gold ring box.\nWe can customize this ring with any design and any natural or lab-created stone. Contact us for a custom piece.\nNeed help deciding between Platinum and White Gold?
