This is a contemporary espresso or Turkish coffee cup manufactured by Güral Porselen, a prominent Turkish ceramics company. The item is crafted from fine bone porcelain, characterized by its stark white color, translucent quality, and smooth, glazed finish. The cup features a spherical body with a small, rectangular-profile handle attached to the side. On the underside of the base, there is a clear manufacturer's backstamp in black ink which reads 'GÜRAL PORSELEN' below a stylized 'G' logo. Smaller text beneath the brand name indicates it is 'FINE BONE PORCELAIN' and mentions 'Transparent - High Quality Limited Edition.' The construction appears precise with thin, elegant walls typical of high-quality bone china. The condition shown is excellent, with no visible chips, cracks, or staining, and the glaze retains a high-gloss luster. Based on the branding and style, the piece likely dates from the late 20th century to the present day, representing modern mass-produced but high-standard tableware. The uncolored, minimalist aesthetic suggests it may be part of a professional hospitality line or a contemporary home set designed for versatility.

I have virtually examined this fine bone porcelain espresso/demitasse cup produced by Güral Porselen. The item exhibits the characteristic translucent quality and 'high-white' brilliance associated with premium bone china. The backstamp is clear and consistent with modern production marks from Güral’s high-end hospitality and retail lines. Based on the visual evidence, the condition is mint/excellent, showing no signs of crazing, rim chips, or utensil marks. The handle attachment appears seamless, indicating high-standard quality control. Market-wise, Güral Porselen is a respected global manufacturer, particularly in the hotel and catering industries. However, because this is a contemporary, mass-produced item rather than an antique or a designer-signed piece, its value is driven by utility and brand prestige rather than rarity. Similar individual pieces sell within the $15–$25 range on the secondary market, though they are most commonly traded in sets of six, which generally fetch $80–$120. The 'Limited Edition' mark on the base suggests a specific production run, but in the current tableware market, this does not significantly inflate value over standard high-quality bone porcelain. While the hallmarks and finish are consistent with authentic Güral Porselen, a definitive authentication cannot be made through images alone. In-person examination would be required to verify the specific gravity of the porcelain and check for 'ping' resonance to ensure structural integrity. Furthermore, official provenance or original retail documentation would assist in confirming the specific line and production year. Scientific testing (X-ray fluorescence) could verify the bone ash content if the material's composition were in doubt.
