I am pleasantly surprised by the colors of the pendants, which more or less match the product image (although in sunlight, my citrine pendant appears more golden yellow than the orange-yellow in the product image, and the blue topaz is more of a watery sky blue, but not so pale that you can't tell it is a blue topaz). Some of the other reviewers mentioned the pendants being bigger than they expected, so I included some measurements for all five pendants. The width is measured for the widest point.

Garnet: 18x5mm; stone alone: 9x5mm
Citrine: 18x6mm; stone alone: 8x6mm
Amethyst: 16x8mm; stone alone: 8mm
Blue Topaz: 17x6mm; stone alone: 9x6mm
Peridot: 17x7mm; stone alone: 7mm

All except the peridot appear flawless to the eye, and even the wisp of inclusion in the peridot pendant is barely visible in sunlight (the color is a bit darker than shown in the product image, a brilliant apple green).  I got them for under 8 dollars per pendant, but even at full price, the quality of the pendants makes purchasing this set worth it.
