Plenty of rainbow titanium jewelry leans on bright purples and pinks. This oval goes the other way. The base tone is platinum, a cool silvery grey, and the rainbow only shows up in flashes at the edges when the stone moves. It is the version for people who want titanium oxide colors without shouting about them.
That quiet look comes from the thin metallic layer on the surface. Light bounces through it and you get a soft metal color change as you turn the stone, from steel to a hint of blue, gold or violet. If you have seen faceted rainbow titanium crystal pendant necklace silver designs and liked the idea but wanted something smoother, this cabochon gives you the same family of color in a calmer shape.
Oval is the most flexible outline in the range. It sits well in a ring, drops neatly from rainbow coloured titanium earrings, and links easily into a bracelet. One of the sizes is long and slim, which makes it good for narrow pendants and bar-style bangles. The back is flat, so the stone rests evenly in a bezel or on a tray.
