Tertia is a charming presentation of three round brilliant lab-made diamonds, each set within their own curved four prong setting, with daylight crossover shoulders and a court profile band. Two choices of either a gentle graduation of side stones or a row of three beautiful 0.50 carat shining diamonds that are equal in size. Stone sizes include a 5.0mm centre man-made diamond with 4.0mm outers, or three 5.0mm man-made diamonds. Shank width is 2.4mm and sank depth is 1.5mm.
