The beads in the promos show a beautiful cerulean blue color similar to Sleeping Beauty turquoise with very little to no matrix visible. That is not the color of the beads I received. The ones I got are a typical common turquoise color with thin black matrix on every bead. I do give allowances due to photography lighting & device screens but the color differences are too apparent. It may seem trivial, given the price, but was counting on a close color match to the promos for a specific project. I can still use them for another purpose as they are pretty & nice quality. Also more information is needed in the ''Details'' section as not certain if these are dyed howlite, magnesite, synthetic or actual stabilized turquoise.
