从Sri Lanka供应商批发进口5.20 Ct Ceylon Blue Sapphire -Untreated — FOB条款

This is a 5.20 carat Ceylon blue sapphire in untreated condition, offered by Gruhabands from Nugegoda, Sri Lanka. The stone originates from the alluvial gem deposits of Sri Lanka, historically known as Ceylon, which produces sapphires prized for their vivid blue colour and transparency. Being untreated means no heat, diffusion, or other enhancement processes have been applied, a distinction that commands premium valuation in the coloured gemstone market. The exact dimensions, cut proportions, and clarity grade are not stated in the source and must be requested from Gruhabands directly.

The sapphire is described as having a deep, vivid blue hue with expert cutting to maximise brilliance and clarity. In the trade, Ceylon blue sapphires typically range from cornflower to royal blue, with the most valued stones showing strong saturation without excessive darkness. Untreated material of this size and origin is increasingly scarce; standard industry practice involves heat treatment to improve colour and clarity in approximately 95 percent of blue sapphires on the market. A 5.20 carat unheated stone therefore represents collectible-grade material, though buyers should insist on independent laboratory certification to confirm the untreated status and geographic origin.

Primary applications include high-end jewellery manufacturing for rings, pendants, and earrings, as well as investment and estate portfolio acquisition. Buyers range from bespoke jewellers and luxury brands to private collectors and gem dealers. Gruhabands offers flexible minimum order quantities and trade terms including FOB and CIF, though exact MOQ, price per carat, and lead time are not specified and require direct confirmation. The supplier address is 525/2/1 Wijerama Junction, Nugegoda 10250, Western Province, Sri Lanka.

Gruhabands is based at 525/2/1 Wijerama Junction, Nugegoda 10250, in the Western Province of Sri Lanka. The supplier holds a harbor trust tier classification on the platform. The response rate is listed at 0.00 percent with zero average response hours, indicating no recorded inquiry responses; buyers should initiate contact through direct channels and assess responsiveness before proceeding. The company specialises in natural gemstones from Sri Lankan sources, with this listing representing an single-stone offering rather than a uniform production run.

The available profile does not state year of establishment, ownership structure, number of employees, annual turnover, nor export licence details. No membership in trade organisations such as the Colombo Gem and Jewellery Traders Association is confirmed. Buyers should request business registration documents, gem dealer licence, and references from previous international clients. The source description claims certified authenticity without naming the certifying laboratory; this is a critical verification point given the value differential between treated and untreated sapphires.
