2.30 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exquisite 2.30 carat oval blue sapphire from Ceylon Sri Lanka presents an immediately measurable set of proportions and cutting characteristics that will appeal to the technically minded collector and jeweller. The stone measures 8.74 by 6.62 by 3.94 millimetres, yielding a depth ratio of approximately 51 percent when calculated against the average of the length and width, a proportion that balances internal light return with face up size. The oval outline is classic and well balanced, offering an ideal platform for both prong mounted solitaire designs and low profile bezel settings. The mixed brilliant cut indicates a hybrid approach to facet architecture, combining a brilliant facet schema on the crown with an optimized pavilion design, implemented to enhance scintillation while preserving colour saturation. The Natural Sapphire Company offers this particular example with documentation of origin and enhancement, heat treated, reflecting standard trade practice and ensuring a stable, permanent improvement to tone and transparency.

From a cutting and finish perspective the gem exhibits meticulous lapidary execution. The crown presents a traditional brilliant facet arrangement with well proportioned star and kite facets that reduce windowing and promote dynamic light return. The pavilion is governed by a mixed schema that moderates facet angles to concentrate blue body colour without sacrificing fire. Facet junctions are sharp and the girdle profile is consistent, which contributes to the reported excellent polish. This high level of polish supports crisp facet reflections, so that under direct lighting the stone yields pronounced scintillation and pinpoint white flashes, while under diffuse lighting it displays even, velvety colour. The oval outline has been cut to minimise bow tie effect, and any remaining dark zone across the centre is shallow and does not materially interrupt the visual performance when the gem is set in standard ring and pendant orientations.

Optically the sapphire is described as transparent with a clarity grade of very slightly included, evaluated at eye level, a condition that is explicit in trade terms and meaningful for valuation. In practical viewing the stone reads as clean at a glance, with minor internal characteristics confined to discrete areas and not impairing the path of light through the crown to the eye. These inclusions serve as natural fingerprints confirming the gem origin, and they do not affect structural integrity or wearability. The colour is assessed as medium intense, a balance that places the tone between light and deep, and yields excellent versatility, allowing the blue to appear lively under both incandescent and daylight spectral conditions. The hue leans to pure blue with a touch of violet that is characteristic of many Ceylon sapphires, producing a vivid but not overly dark presentation. Pleochroic behaviour is present in the predictable manner for corundum, with subtle shifts in blue saturation as the stone is rotated, which enhances its three dimensional colour interest when mounted.

This sapphire is inherently versatile and is engineered by its proportions and cut to function across a broad spectrum of jewellery applications. In daily wear the medium intense tone and very slightly included clarity make it well suited to protective bezel or low profile prong settings, which preserve the gem while allowing practical use. For formal applications the oval mixed brilliant cut delivers strong table reflections and scintillation that complement high contrast settings, such as three stone white diamond shoulders or halo arrangements, and the slightly violet leaning blue plays especially well against cooler white metals while retaining warmth in yellow gold settings. Heat treatment is documented and applied in a controlled manner to stabilise colour and clarity, a practice that is widely accepted and that ensures long term colour stability. When you select this sapphire through The Natural Sapphire Company you receive not only this precisely described item, but also the benefit of provenance, craftsmanship insight, and fitting recommendations from specialists who understand facet geometry, colour grading, and setting compatibility for long term enjoyment.
