Antiques and Jewelry
For the inveterate antiquer, a handheld magnifier is a must-have item (and a highly appreciated gift). The antique world abounds with tiny detail - engraver's marks on silver, factory and artist markings on ceramics, cracking and crazing of glazes, real (or fake?) wormhole patterns in furniture, wear and patina on plated and gilded surfaces... the serious antiquer always needs a closer look.
For this activity, a medium-power magnifier is best - a Zeiss D12-AR is an excellent choice for viewing ceramics and furniture, while a Zeiss D16-AR is better for close inspection of gold and silver pieces, and costume jewelry. For higher-power viewing of semi-precious stones in jewelry, the ZeissD12+24 multi-lens pocket loupe is an excellent companion magnifier, while for appraising fine gemstones, the Zeiss D40 10-power pocket loupe is the standard of the trade.
