0.65 Ct. Purplish Blue Sapphire from Ceylon (Sri Lanka)

This pear shaped sapphire presents precise proportions and measured craftsmanship, weighing 0.65 carat, and measuring 6.05 x 4.04 x 3.36 mm, with a length to width ratio of approximately 1.50, and an overall depth percentage of approximately 66.6 percent, dimensions that yield a well balanced teardrop that sits elegantly in a variety of mounting styles. The cutting style is faceted, executed as a mixed brilliant cut, incorporating brilliant facets on the crown and carefully coordinated pavilion facets that maximize return of light while preserving color saturation. The mixed brilliant strategy here reduces the washed out appearance that can occur when color is too shallow, and it avoids the dead face up look that an overly deep pavilion can cause, so the design achieves a technical equilibrium between scintillation and hue. The excellent polish on all facet planes contributes to crisp facet junctions and lively facet contrast, and the precision of the cut is immediately evident in the symmetry of the outline and the even dispersion of light from crown to pavilion.

Color and clarity characteristics of this stone speak to both its origin and its optical behavior, the hue being purplish blue with an intense color intensity that reads strong and saturated under daylight and artificial light. Sourced from Ceylon, Sri Lanka, this sapphire exhibits the regional tendency toward bright, lively blue with violet inflection, a balance that is prized for face up presence in smaller calibrated sizes. The stone is heat treated, a stable and widely accepted enhancement that optimizes color and does not compromise structural integrity when the gem is set and worn normally. Clarity is graded as very very slightly included, evaluated at eye level, which indicates only minute internal features that do not interrupt transparency or diminish the gem s ability to return light, and these subtle inclusions often act as internal landmarks that attest to natural origin without impacting brilliance. Optical properties typical of corundum, including a refractive index in the range associated with sapphire and notable pleochroism, are managed by the cutter so that the mixed brilliant facet pattern presents the most desirable face up color while allowing flashes of lighter and deeper tones as the gem moves.

From a practical and longevity perspective this sapphire is a technically durable choice for everyday jewelry, corundum being second only to diamond in hardness with a Mohs rating of 9, a material characteristic that supports long term retention of facet sharpness and polish under normal wear. The combination of excellent polish, stable heat treatment, and the mixed brilliant cut ensures that its natural beauty will continue to captivate over the years, maintaining lively scintillation, controlled color saturation, and structural resilience. For mounting recommendations, precision set prong settings accentuate the pear silhouette and allow maximum light entry to the crown, while low bezel or partial bezel treatments protect the vulnerable point of the pear and are appropriate for active lifestyles without unduly sacrificing brilliance. For designs that emphasize perceived size and sparkle, a halo with well matched melee accent stones will enhance apparent diameter and create dynamic light play, while a solitaire three stone composition emphasizes the purity of the single center gem. Cleaning by warm soapy water and a soft brush is recommended for routine care, with professional ultrasonic or steam cleaning acceptable for heat treated sapphires after consultation, and routine inspections of the setting will preserve the piece for generations.

The Natural Sapphire Company presents this calibrated pear as a gem that combines measured cutting decisions with responsible sourcing information, a stone that exhibits technical attributes sought by knowledgeable buyers, including exact dimensional balance, a refined mixed brilliant faceting strategy, intense purplish blue color from Ceylon, and an eye level clarity that is very very slightly included. For collectors and clients who demand both quantifiable specifications and enduring aesthetic performance, this sapphire offers a rare intersection of optical engineering and natural charm, assuring that its presence in a commissioned piece will remain compelling and visually engaging through years of wear.
