19.69 Ct. Topaz from Ceylon (Sri Lanka)

One beautiful transparent 19.69 carat oval Swiss blue topaz, with dimensions of 19.64 by 14.73 by 9.95 millimeters, offers a commanding presence that outshines many stones of similar color on the market, and its mixed brilliant cut maximizes scintillation and lively fire in a way that many standard step or simple brilliant cuts do not. This gem is eye clean when evaluated at eye level, with vivid color intensity and an excellent polish, which together deliver a clarity and surface finish that make the color read pure and saturated without the visual distractions often found in lower grade material. Compared with aquamarine alternatives at this size, this Swiss blue topaz delivers a more vivid blue tone at far better value per carat, and compared with blue sapphire options it offers a larger apparent size and brighter flash for clients seeking bold, wearable blue at a fraction of the price. Enhanced by irradiation to achieve its desirable hue, this topaz presents stable color when properly cared for, and its combination of size, cut, and polish positions it as a superior choice for statement rings, dramatic pendants, or a striking center stone in a bespoke piece.
