Pre-owned 10K yellow gold three-stone ring featuring a striking blue gemstone that tests as topaz on a Presidium gem tester and other standard testing methods. The stone shows a vivid blue hue and is believed to have undergone color-enhancement treatment, most likely through irradiation and gentle heat, though other treatments cannot be ruled out. The gem is bright, eye-clean, and well-cut with excellent brilliance.
It is accented by two clear white topaz side stones in a classic three-stone setting, all securely prong-mounted in solid 10K gold. The ring is hallmarked “10K” and “THAILAND” inside the band, weighs 3.65 grams, and measures size 7 US.
This piece was acquired from an estate; no papers or lab certification are included. It remains in excellent pre-owned condition with light wear consistent with age. A beautiful and timeless gold topaz ring with graceful color and sparkle.
