One electronically tested 925 silver ladies cast & assembled blue topaz and white sapphire pendant with chain. The pendant features a blue topaz set within an elaborate botanical white sapphire ribbon bezel, completed by a hidden white sapphire set bail.

One prong set oval mixed cut natural blue topaz, measuring 21.50 x 17.00 x 12.10mm, approximate weight of 32.88ct., clarity is eye clean, type I, medium dark, moderately strong, very slightly greenish blue color, (GIA vslgB 6/4), cut is good. Transmitting light with no distortion, transparent. 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.

One hundred nine prong set round mixed cut natural white sapphires approximate total weight of 2.40ct., clarity is eye clean, colorless, very slightly grayish, white color, (GIA W 0/3), cut is good.
