Lupron is not a contraceptive, however, and it is possible for pregnancy to occur during the first few weeks of therapy. Non-hormonal birth control should be used to prevent pregnancy. Suitable forms of contraceptives include condoms, diaphragms with contraceptive jelly, and non-hormonal IUDs.
VVS is great clarity to have if you donât want to pay for Flawless or Internally Flawless diamonds. The G.I.A. (Gemological Institute of America) grades clarity using six main categories: Flawless (FL), Internally Flawless (IF), Very, Very Slightly Included (VVS), Very Slightly Included (VS), Slightly Included (SI), and Included (I).
So, if VVS is a better clarity grade, where does VS clarity have an edge? The answer is simple: price. A VS-clarity diamond will usually be cheaper than a comparable VVS-clarity one, and the difference can be as big as a couple of thousand dollars. Of course, a superior cut or color can make a VS diamond more expensive than a VVS stone, so you should also evaluate other quality characteristics.
