This Platinum Diamond Three Stones Engagement Ring Mounting features two 0.33ct round diamonds (each) on the sides and is available in Platinum, 18k or 14k yellow, rose or white gold and various sizes. This three stone diamond ring mounting can also be custom built to your specifications with diamond quality of your choice. It might accommodate from 0.33ct to 1.50ct center stone and from 0.33ct to 1.25ct side diamonds (each). In this current configuration it will accommodate a 0.33ct round center stone (not included). If you need it to accommodate a larger stone please contact us for a quote as the price might be higher (the mounting might be heavier and we might have to use larger side stones to match the larger center stone). Please note: it will take us 3-5 business days to make this ring for you so please plan accordingly. Please contact us at 212-398-3123 if your size or desired option is not listed.
