I am guessing that the seller uses one picture for a lot of similar sizes gems. I plan to use this one as a practice for gem cutting but was hoping for something a bit less irregular. Either way you can't really beat the price. The 2nd one I received was even better. It still was cloudy but was a lot more translucent and a much better shape. Its very pretty just not transparent. Review: Nice - Nice. ## Features - The color of a blue sapphire is more important than its clarity. Sapphires are rarely completely clean and even very expensive stones can be slightly included. Subtle differences in color can make great variations in valuations of fine gemstones. Fine loose gemstones of good color and clarity are always rare and valuable. Highly saturated medium or medium dark blue tones are best, blue sapphires which are too dark or too light are worth considerably less. - Color zoning is responsible for certain Sapphires having lighter and darker colors in different parts of a crystal. Some Sapphire gemstones may even be multicolored such as purple and blue. Sapphire is a tough and durable gem, and the only natural gemstone harder than Sapphire is Diamond. Despite this, Sapphire is still subject to chipping and fracture if handled roughly, and care should be taken to ensure it is properly handled. - Display a lighter and more intense color when viewed at different angles. Some pleochroic Sapphire is blue when viewed at one angle, and purple at a different angle. Color zoning, which forms from growth layers that build up during the formation of the stone, may also be present in certain Sapphires. - Our Expert gemologists verified this Blue Sapphire which passed many quality base tests and get stone certified through which we are completely assured of Top Quality Gemstone. Only after that, we deliver stones to you because we also, care about your loved ones. - Perfect For: Jewelers, Jewelry makers, Goldsmiths, Designers, Craftsmen, Collectors or a gift for the special one. Each and every stone is unique and you will receive ones similar to the image shown. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07MC4CHZM | | ASIN | B0D7YTFTYY | | Best Sellers Rank | #170,338 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #5 in Loose Gemstones | | Brand Name | GEMHUB | | Clasp Type | no-clasp-type | | Customer Reviews | 3.9 3.9 out of 5 stars (809) | | Date First Available | June 24, 2024 | | Department | Unisex Adult | | Gem Type | Sapphire | | Grade Rating | AAA | | Manufacturer | Hamlet e commerce | | Metal Stamp | Sterling silver | | Primary Stone Gem Type | Sapphire | | Ring Size | 4 | | Stone Clarity | SI1 | | Stone Color | blue | | Stone Cut | Very Good | | Stone Treatment Method | Heat-treated | | Stone Weight | 15 Carats | | Total Gem Weight | 15 carats | | Unit Count | 1 Count | ## Images ![Natural Blue Sapphire Rough Gemstones 8-200 Carats Raw Crystals and Healing Stones Loose Gemstone Necklace For Women And Men - Image 1](https://m.media-amazon.com/images/I/61KNISfSwBL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Where do these gemstones come from?** A: These gemstones come from all across the world from the thousands of mines present.
