One electronically tested 14KT white gold ladies cast blue topaz and diamond ring with a bright polish finish. The featured blue topaz is supported by a lattice under gallery and diamond set shoulders, completed by a three millimeter wide band. Identified with markings of "14K". Condition is new, good workmanship. Containing: One prong set rectangular step cut natural blue topaz, measuring 20.20 x 15.50 x 9.00mm, 6% bulge factor, approximate weight of 31.63ct., clarity is eye clean, type I, dark, very slightly grayish, greenish blue color, (GIA gB 7/3), cut is good. Transmitting light with no distortion, transparent. Refractive index testing results of 1.61 to 1.62. This is a conclusive result for topaz. Graded in the setting. A deposit of a thin layer has been applied to the topaz to produce the intense color effect. The process utilizes a very high temperature treatment, diffusion of ions into the topaz, plus in some cases neutron bombardment has been used to create the color center. Diffusion processes causes the added ions to become part of the crystal surface with no distinct boundary. Do not put a gem treated in this manner into an ultrasonic cleaner. Sixty prong set round brilliant cut diamonds, measuring 1.60 - 1.40 x 0.90mm (depth est.) approximate total weight of 60 Stones = 0.83ct. Graded in the setting. Clarity: SI-1 to I-1. Color: G - I.
