Blue rutile includes types with crocidolite, and another type, so-called tourmalinated quartz, which has inclusions of indigoite tourmaline needles. There may be other minerals as my knowledge is not yet established, and dumortierite in quartz, which is popular in the market, can be considered as blue rutile because it is quartz with blue needles, but currently, there are mainly the above two types circulating in the market. Blue rutile containing tourmaline needles is characterized by the needles being more clearly visible compared to the crocidolite type. Tourmaline has such a wide variety of colors that there are almost no colors that don't exist. Therefore, theoretically, there should be as many cases of it being incorporated into quartz as there are colors. In fact, black rutile containing well-known black tourmaline is common, as is green rutile containing green tourmaline. Rare examples like pink tourmaline in quartz and watermelon tourmaline in quartz have also been confirmed. I think the rarity is directly correlated to the rarity of the tourmaline inside. Therefore, quartz containing indigoite tourmaline is quite limited in number. Please consider it as it is rare to have inclusions with a clearly visible blue color.
