2.37 Ct. Topaz from Ceylon (Sri Lanka)

This sky blue topaz from The Natural Gemstone Company is a standout choice for anyone seeking a refined and wearable center stone, one that delivers clarity, elegance, and excellent value. We present a transparent 2.37 carat emerald cut sky blue topaz with precise dimensions of 9.01 x 7.03 x 4.51 mm, a very light color intensity, and a clarity grade described as very very slightly included when evaluated at eye level. The stone is beautifully finished with an excellent polish, which elevates the clean, glassy appearance typical of topaz while allowing its soft sky blue hue to read clearly under natural light. Sourced from Ceylon Sri Lanka and enhanced by irradiation to achieve its alluring blue tone, this gem offers the natural origin story collectors and designers appreciate, while remaining accessible compared to rarer blue gems. Compared with synthetic alternatives and common simulants, this natural topaz offers genuine gemological attributes, including the subtle internal character that signals authenticity, and the stable color enhancement that modern irradiation treatments provide.

The emerald cut shape is a particularly compelling advantage when planning custom jewelry, because its long, rectangular step facets emphasize clarity and create a sophisticated, architectural look. Unlike brilliant cuts which hide inclusions behind scintillation, the emerald cut showcases the stone itself, making it well suited for a topaz with very very slight inclusions and excellent polish. The proportions of this stone, nine point zero one by seven point zero three by four point five one millimeters, are ideal for a timeless solitaire engagement ring, a refined three stone setting, or an elegant pendant that hangs with presence without overwhelming the wearer. In comparison to round or oval cuts of similar carat weight, an emerald cut often appears larger face up, giving more visible surface area for the color to display and for custom design features to interact with light. Compared with aquamarine which may show paler tones at similar sizes, and compared with blue sapphire which often commands a premium for deep saturation, this sky blue topaz represents a balanced option for those seeking clarity, cool color, and affordability, while still preserving the sense of luxury a custom piece deserves.

For custom settings the dimensions and step cut of this topaz open many creative directions while ensuring practical wearability. The stone is perfectly proportioned for classic prong mounts which maximize light entry and allow the step facets to reflect broad flashes, and it also performs beautifully in low profile bezel settings which protect the girdle and are ideal for daily wear. The rectangular shape lends itself to east west rings for a modern twist, and its face up size makes it a striking center for a halo where smaller diamonds or sapphires can amplify the overall presence. The depth of four point five one millimeters offers a balanced pavilion that refracts light without causing the stone to sit too high, which is often a concern with deeper cuts. Compared with similar carat stones in round or cushion cuts, this emerald cut topaz will read as elongated and elegant on the finger, benefiting designers who want to emphasize clean lines and vintage inspired geometry. For earrings and pendants the nine by seven millimeter footprint fits standard mounting templates, allowing clients to mix and match stones from The Natural Gemstone Company for coordinating sets with consistent proportions.

When advising clients and designers we emphasize provenance, treatment disclosure, and the ways these factors inform final design choices. Origin from Ceylon Sri Lanka brings a narrative of classic gem localities while the irradiation enhancement is a common, stable treatment used to bring out blue tones in natural topaz, a process that has been industry accepted for decades. The clarity grade very very slightly included indicates the stone is essentially eye clean in most mounting styles, which makes it particularly well suited to an emerald cut where transparency and step facet interplay are focal points. The excellent polish ensures crisp facet junctions and a clean table reflection, attributes that contribute directly to perceived value when compared with lower quality stones or mass market imitations. At The Natural Gemstone Company we pair this gem with design consultation to recommend metal type and setting style, whether your client desires the cool contrast of platinum, the warm halo of yellow gold, or the modern clarity of white gold. This topaz provides a superior balance of value, appearance, and design flexibility when compared with many alternatives, and it stands as an intelligent choice for craftsmen and clients aiming to create heirloom quality custom jewelry.
