Some Orrefors items may only feature a discreet etching or marking to indicate authenticity, while others may be signed with the Orrefors logo or the designer's name.

The best color diamond is generally considered to be the colorless or white diamond. These diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). In the diamond industry, colorless diamonds with a higher grade (closer to D) are highly valued due to their rarity and desirability. Colorless diamonds allow more light to pass through, creating a dazzling sparkle and enhancing the overall brilliance of the stone. They are often more expensive compared to diamonds with visible color. However, it's important to note that diamond color preference is subjective and some individuals may prefer fancy colored diamonds like vivid yellows, pinks, or blues, which are also highly sought after and can be quite valuable.
No, not all pieces of Sevres porcelain are marked with a signature. While many Sevres porcelain pieces are indeed marked, it is not a guarantee that every item will bear a signature. The presence of a mark depends on various factors such as the time period, the specific artist or designer, and the intended use of the piece. Sevres porcelain, produced in the famous French royal porcelain factory in Sevres, has been highly regarded for its exquisite craftsmanship and quality since the 18th century. The factory initially used distinctive marks to identify and authenticate their creations. These marks often included monograms, symbols, or specific inventory numbers. However, not all pieces were marked, especially those created during the early years of the factory's production when marking was less standardized. It is important to note that the absence of a mark does not necessarily indicate a piece is not genuine. Sevres pieces without marks may still exhibit characteristics such as the factory's unique style, refined techniques, and exceptional quality that can help identify them as authentic.
