Beautiful flower, but as I'm sure other members will tell you, it's impossible to POSITIVELY identify a hybrid based on appearance. The best you should expect is a "looks like".
A picture of the whole plant and spike would be helpful in narrowing down the type, particularly whether a Laelia anceps hybrid like Lc. Hsin Buu Lady is a possibility. The flower is nearly as close a visual match to Ctt. Jewel Box types. But any identification of an unknown hybrid is almost always limited to "looks like" not "is".
