Premium prices can still be demanded for fine, top gem quality Pakistan Peridot. The U.S. has also become a major source for Peridot since the world's largest known deposit is on the San Carlos Apache reservation 80 miles west of Phoenix, Arizona, but this material rarely cuts gems above 10 carats.
Implantation takes place when a fertilized egg is embedded into the inner wall of the uterus. This occurs about one week after your ovulation, although this may range from 6 to 12 days. It will take another 3 to 4 days (approximately 9 to 16 days post-ovulation) for your blood test to become positive. After 2 to 3 days an early urine test for pregnancy or a Home Pregnancy Test (HPT) may turn positive. In many women this test will be positive after they miss a period, which is approximately one week after the implantation of the fertilized egg. Although some manufacturers of home pregnancy tests say that the test gives positive results before you miss a period, only about a quarter of expectant women test positive two days before they miss a period, and less than half on the day before expected period.
Methods of confirming a positive pregnancy test after implantation bleeding.

It can be detected by an immunoassay (analysis of a blood serum, taken from a vein in special laboratories).
