After breaking several sales records at auction last year, colored diamonds might be one of the best investment gifts for Valentine’s Day. The One and Only One, a group of seven U.S. jewelers, is offering several rare stones from $2 million to $10 million. Standouts include a 10.2-carat canary-yellow diamond cocktail ring; a pair of earrings featuring a 2.23-carat and a 2.35-carat green diamond surrounded by pink and white diamonds; and the six-strand Majestic Pink Bracelet, composed of 204 square-cut marquise pink diamonds totaling 43.34 carats.
