Size and Weight
-- Gems are always measured in Millimeter (mm), 1 inch = 25.4 mm
-- Dimensions are given as length x width x depth, except for round stones which are diameter x depth
-- Select gems by size, not by weight! Gem varieties vary in density, so carat weight is not a good indication of size

The picture are greatly enlarged to show details and stone size may vary slightly from piece to piece. It is the equivalent to viewing the stone under magnifying glass or microscope. We can see flaws visible that aren't visible to the naked eye.
Color may not appear as exactly in real life due to variation between computer monitors. The more important it is the gemstones and diamonds reflect 100 percent of the light falling on it back to the eye. So because of the camera, it give a harsh black reflections that we see on the photos. I try to take photos that show the true color and structure (shape and imperfections) of my stones. In certain cases, it is not easy. If you not sure feel free to convo me if you have questions.
It is absolutely genuine and natural. I guarantee that my gemstones are 100% authentic and accurately represented in my listings.
I offer a 10-day, money back, as long as your item is in its original condition.
This stone will be shipped fully insured.
