1.60 Ct. Sky Blue Topaz from Brazil

This transparent 1.60 carat oval sky blue topaz presents precise proportions, with dimensions of 8.29 by 6.26 by 4.08 mm, a length to width ratio of approximately 1.32, and a measured depth of roughly 56 percent of the average diameter. The stone has been fashioned in a mixed brilliant cut that combines a brilliant facet pattern on the crown with modified step and brilliant facets on the pavilion, a configuration that enhances both return of white light and internal scintillation. The table facet is well centered, the girdle appears proportionate for secure setting, and the excellent polish yields crisp facet junctions and minimal surface abrasion under loupe inspection. Color is graded as medium intensity sky blue, exhibiting even saturation across the stone that benefits from the cut geometry to deliver lively dispersion without overpowering tone. Clarity is evaluated as very very slightly included at eye level, with only minute pinpoint inclusions that do not interrupt face up transparency, preserving clean windowing and strong light performance for precision settings and fine jewellery mounting.

From a treatment and provenance perspective this topaz originates from Brazil and has undergone irradiation enhancement to produce its sky blue hue. Irradiation is disclosed openly as a stable, industry standard treatment for topaz that, when conducted in licensed facilities and followed by appropriate post treatment handling, yields durable color suitable for everyday wear. For the conscious collector who values traceability and ethical sourcing, The Natural Gemstone Company provides documented provenance and due diligence information on request, and we partner with suppliers who adhere to responsible mining practices, fair labor standards, and community reinvestment measures. The combination of exacting lapidary craftsmanship, transparent treatment disclosure, and documented origin makes this stone appropriate for a curated, ethically minded collection, serving both technical connoisseurs who prioritize cut and optical performance, and conscientious buyers who require clear sourcing and treatment transparency.
