This auction also showed instability in foreign exchange and gold markets, making both sellers and buyers sensitive in their movements. Considering future trends, it seems that selling early across all product categories might be the right timing.
Price weakness was observed, and it seems better to identify the selling timing early. A concurrent exhibition in Hong Kong showed similar trends, suggesting a prolonged global downturn. Nevertheless, high-quality VS1/VS2 class diamonds with good color commanded high prices. Diamonds below 0.3 carats have low demand, so transactions with controlled purchase prices are advisable. Melee diamonds and fancy color diamonds saw some high-value trades.
Overall trading was more active than for diamonds. However, colored stones with noticeable inclusions traded at lower prices, so stones with visible flaws or those showing a declining trend due to differences in filling treatment materials require caution. Buyers showed a strong tendency to seek good stones, leading to high-value trades for rare items.
Little fluctuation was seen due to exchange rates. Rolex watches with guarantees commanded high prices. Omega, similar to the previous auction, showed a trend of high-value trades, and accessories are also highly valued, so caution is needed. Accessories are also important for brand jewelry.
