Yellow sapphires
Yellow sapphires are not in common use, but they are to be seen as center stones of larger brooches and pendants. They should be bright, free from flaws, and the color should be a clear, strong yellow. Many stones are much flawed, and these are of very little value. Fancy color diamonds earrings should be carefully distinguished from topaz, although values are about the same.
Cabochon stones are not in great demand, and they are seldom of fine quality. Star sapphires, however, reach $140 (£50) a carat and more if over five carats and if they show a distinct clear star and the background is blue. Their value is greatly reduced if the star is not central and if it is indistinct. The body color must be blue to make the stone of fine quality, and specimens having these essential factors are rare. Generally, the fancy yellow pendants background is grey or too light in color, and these ordinary stones fall in value to only a few shillings per carat.
