0.52 Ct. Ruby from Ceylon (Sri Lanka)

This transparent 0.52 carat oval red ruby from The Natural Ruby Company is a finely balanced combination of color, cut, and clarity, suited for a discerning buyer. The stone measures 6.06 by 4.14 by 2.34 millimeters, and is fashioned in an elegant oval with a mixed brilliant cut that blends step and brilliant faceting to optimize face up color and scintillation. The clarity is graded slightly included at eye level, indicating small internal characteristics that are visible under close inspection but do not compromise the gem transparency or visual appeal. The color presents a vivid intensity, a pure red with lively saturation that reads well in various light conditions, and the polish is excellent, producing crisp facet junctions and a bright surface finish. The stone has been heat treated, a widely accepted and stable enhancement in trade that improves color and clarity while preserving the natural origin and structure of the corundum.

From a gemological perspective the slightly included clarity grade signals that the stone retains natural character, with internal features that confirm its authenticity and origin while remaining attractive to the eye. Evaluated at eye level means the inclusions are observed without magnification, but in this example they are minor and do not create significant windowing or dead areas. The mixed brilliant cut contributes to both light return and color concentration, by distributing flashes of white light across the pavilion facets while retaining depth of hue in the crown. The measured depth proportion of approximately 46 percent, calculated from the stone proportions and average diameter, places the gem in a balanced range for oval cuts, avoiding an overly shallow spread that would wash out color, and avoiding excessive depth that would reduce apparent size. The excellent polish further enhances visual performance by allowing maximum reflection and minimal surface disruption.

The provenance from Ceylon Sri Lanka adds meaningful context and value for educated buyers, because Sri Lankan rubies are known historically for their brightness and attractive tone. The geology of Sri Lanka produces chromium bearing corundum that often displays a vivid, slightly lighter red spectrum compared with some other origins, producing lively saturation that reads brilliantly in moderate sizes. Collectors and connoisseurs value origin information because it links the material to well documented mining and cutting traditions, regional characteristics, and established market preferences. Stones from Ceylon command respect in the gem trade for their combination of appealing color, good clarity, and classical appearance, and this ruby exemplifies those attributes. At The Natural Ruby Company we place emphasis on provenance and responsible sourcing, and we provide clear disclosure regarding treatments and origin to support buyer confidence.

For the buyer looking to invest in or set a high quality colored gemstone, this 0.52 carat Ceylon ruby represents a compelling option. The vivid color and excellent polish translate into strong face up presence, making the stone suitable for a center in a fine ring, a refined pendant, or as the focal point in a bespoke piece. The heat treatment is a standard and accepted enhancement when fully disclosed, and it preserves structural integrity while improving visual qualities, therefore maintaining marketability and long term value. Buyers may wish to request independent gemological documentation if a full origin and treatment report is required for insurance or resale purposes, and The Natural Ruby Company can assist with guidance on third party laboratories. Care recommendations include avoiding sudden temperature extremes and harsh chemicals, and having the setting checked periodically by a professional jeweler to protect the stone and its mounting. Overall this ruby combines credible origin, responsible disclosure, and strong aesthetic performance, offering a balance of rarity and practicality that educated buyers will appreciate.
