A 1/3 carat blue diamond is tension-set in this 14k white gold solitaire ring, from Apples of Gold Jewelry. What makes tension-set rings and engagement rings unique is that the precious metal holds the stone in place without the use of prongs, leaving the surface of the blue diamond visible to the eye, as compared to traditional settings which cover over a portion of the diamond.
The band of the 14k white gold ring measures approx. 2.2mm at the widest point and tapers to 1.4mm at bottom. The head height is approx. 4mm tall and the ring weighs approx. 4.2 grams of 14k solid white gold.
The blue diamond solitaire center-stone is a minimum of 0.33 carats.
Also available in 1/2 carat or 1 carat sizes, shown below.
