Tiffany & Co. is known for their high-end jewelry but today they’ve launched an “Everyday Objects” line that transforms everyday items into expensive objects. One of the more notable items are the $1500 Building Blocks that look like your favorite construction toys. The blocks are made out of sterling silver and American walnut and have various shapes like 2×2 and 2×3. One of the bricks that LEGO does not produce are 2x5s which this set has four of, one of which is complete sterling silver.
If money is no object then you may be interested in the Tiffany & Co. Everyday Objects Building Blocks. Of course, engraving is a little extra but since you’re already dropping $1500 on it, a little bit more is nothing. I can think of a number of LEGO sets that I can drop this amount of money on.
