Project description copywriting

My website has about 240 silver jewelry items that need descriptions. They just need short descriptions of around 40-50 words that describe the items briefly and includes some creative thoughts that makes the product more appealing. All descriptions have be uniquely written although some products are similar in material and designs. The only information that will be given is a picture of the jewelry. The collection includes ring, earrings and necklaces with sterling silver and different stones such as amethyst, carnelian, jade, agate, rose quartz and swarovski crystals. Winner of the project is expected to do some research on the underlining materials before writing the descriptions. The price for 10 descriptions is $2. So the entire project will amount to about $50. However, a test run will be done on 20 product before the whole project is awarded.
