Pink sapphire vs blue sapphire which holds value better as a Ceylon gem souvenir

Three Ceylon sapphire categories for buyers. (1) Classic Ceylon BLUE: the most internationally recognised and resaleable, fine cornflower-blue 1ct unheated certified runs roughly 800-2000 USD depending on saturation, clarity and cut. The market is deep, easy to value, and demand is steady globally. (2) PINK sapphire: less common, very pretty, but the market is narrower than blue, so resale can be slower; 1ct unheated pink certified runs 400-1200 USD. (3) PADPARADSCHA (the rare pinkish-orange "lotus blossom"): exceptionally rare and arguably the most prestigious Ceylon gem; a true unheated certified 1ct can run 3000-8000 USD or much more if exceptional. Investment-wise, blue and padparadscha hold or grow value most reliably; pink is a beautiful personal piece but appreciates slower. ALL purchases: insist on NGJA-registered dealer, independent lab certificate (GIA, NGJA, Gübelin, SSEF), and the tourist invoice for VAT-free export.
