Peridot belongs to the forsterite-fayalite mineral series which is part of the olivine group. It is one of the idiochromatic gems, meaning its color comes from the basic chemical composition of the mineral itself, not from minor impurities, and therefore will only be found in shades of green. In fact peridot is one of the few semi-precious gemstones found in only one color.
They have highly sensitive blood tests that can detect the pregnancy hormone (hCG) a few days earlier around day 3 to 4 after implantation. Again, some women have had positive urine tests as early as 2 to 3 days after implantation and others have had to wait up to a few weeks.
You should wait to take a pregnancy test until the week after your missed period for the most accurate result. If you donât want to wait until youâve missed your period, you should wait at least one to two weeks after you had sex. If you are pregnant, your body needs time to develop detectable levels of HCG. This typically takes seven to 12 days after successful implantation of an egg.
