0.65 Ct. Topaz from Ceylon (Sri Lanka)

This listing describes a transparent blue topaz, emerald cut shape, weighing 0.65 carat, with dimensions of 6.03 x 4.02 x 2.91 mm. The stone originates from Ceylon Sri Lanka, and it displays an intense color intensity that is evenly distributed across the pavilion and crown. Clarity is graded as very very slightly included, evaluated at eye level, indicating that the gem appears effectively eye clean with only minimal internal features visible under close inspection. The emerald cut emphasizes the stone s inherent clarity and color, and an excellent polish produces crisp facet junctions and strong light return along the long step facets. This blue topaz has been treated by irradiation to achieve its saturated hue, a common and stable enhancement for topaz when handled within appropriate care parameters. The Natural Gemstone Company presents this gem with full disclosure of treatment and origin, and with attention to cut proportions that balance brilliance and color.

Durability characteristics make this blue topaz well suited for regular wear, while also defining simple precautions to maintain its condition. Topaz rates eight on the Mohs hardness scale, which gives it substantial resistance to surface abrasion and scratching in everyday environments. That level of hardness means the gem can withstand contact with many common materials, and it will retain a polished surface when worn as a ring, pendant, or earrings. At the same time, topaz has a distinct cleavage plane, which can make it susceptible to chipping or splitting if subjected to a sharp blow along that plane. For this reason, settings that offer greater protection at the girdle and corners are recommended, and care should be taken to avoid hard impacts. The irradiation treatment used to produce the intense blue color is stable under normal light exposure and ordinary daily conditions, however exposure to high temperatures during repair work or to aggressive chemical environments can affect color stability and the integrity of the stone. For routine cleaning, warm water with a mild detergent and a soft brush or cloth is the preferred method. Avoid steam cleaning and avoid prolonged exposure to strong acids, alkalis, or bleach. Periodic professional inspection of the setting is advised to ensure prongs remain secure and to limit the risk of accidental contact that could stress the cleavage direction.

Practical considerations for jewelry design and daily wear focus on protective yet aesthetically appropriate mounting options and on the stone s dimensional suitability for a variety of pieces. The 6.03 x 4.02 x 2.91 mm emerald cut in a 0.65 carat weight is proportioned to work beautifully as a center stone in a refined solitaire ring, a secure bezel or partial bezel setting, asymmetric or halo designs that support the corners, or as a pair of matched stones in classic stud or drop earring configurations. The emerald cut s broad facets and long lines present the intense blue color in a calm, architectural manner, making the gem particularly effective where color saturation and clarity are the primary visual attributes. The excellent polish enhances facet contrast and contributes to a lively surface appearance even in softer lighting. For customers seeking a durable gemstone for daily wear, this sample balances practical resilience and visual strength, provided routine precautions are observed. The Natural Gemstone Company can supply additional information on setting recommendations and care guidelines to ensure that the gem performs well as a wearable piece over many years, maintaining both its polished finish and its vivid blue character.
