The most popular cuts for sapphires are oval, square and pear. These are commonly used for all types of jewelry like rings, pendants and earrings. The sapphire is formed with a hexagonal crystalline structure. This enables it to be cut into a variety of shapes that are durable even with regular wear. Sapphires are also available in all other popular shapes like marquise, heart, antique-cushion and round.<img src="https://sourcing-media.hktdc.com/product-original/Biron%C2%AE-20Lab-grown-20Blue-20Sapphire-20Square-20Shape/43c2746ee8824b0aa2bc531918f3e3cd" style="width: 300px;" class="fr-fic fr-dib" data-productmediaid="43c2746ee8824b0aa2bc531918f3e3cd" data-relationshipid="c704a0941f5441bc95deb2b168ee393b">Customized shapes and cuttings are available on order basis.&nbsp; Square Shape: This beautifully unique shape is nearly identical to the emerald-cut, except that it is square which maximizes sapphire’s clarity.<img src="https://sourcing-media.hktdc.com/product-original/Biron%C2%AE-20Lab-grown-20Blue-20Sapphire-20Square-20Shape/cb20d1f1671a4d749854671a6735c1b0" style="width: 300px;" class="fr-fic fr-dib" data-productmediaid="cb20d1f1671a4d749854671a6735c1b0" data-relationshipid="8f03398dae7f4f808811ba937a4ec77e"><table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse;width:472pt;" width="629"><tbody><tr height="21" style="height:15.75pt;"><td colspan="2" height="21" style="border-right:1.0pt solid black; height:15.75pt;width:472pt;" width="629"><div style="text-align: center;">Product Description</div></td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Product Name</td><td style="border-top:none;border-left:none;">Biron® Lab-grown&nbsp;<span style="color: rgb(65, 65, 65); font-family: Roboto, 微軟雅黑體, &quot;Microsoft JhengHei&quot;, 微軟正黑體, Arial, sans-serif; font-size: 18px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">Blue Sapphire&nbsp;</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Gemstone Type</td><td style="border-top:none;border-left:none;">Lab-grown</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Species</td><td style="border-top:none;border-left:none;">Corundum</td></tr><tr height="25" style="height:18.75pt;"><td height="25" style="height:18.75pt;border-top:none;">Chemical Composition</td><td style="border-top:none;border-left:none;">Al2O3&nbsp;Aluminum Oxide</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Mohs' hardness</td><td style="border-top:none;border-left:none;">9</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Refractive Index</td><td style="border-top:none;border-left:none;">1.762-1.788</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Double Refraction</td><td style="border-top:none;border-left:none;">-0.008</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">Dispersion</td><td style="border-top:none;border-left:none;">0.018(0.011)</td></tr><tr height="21" style="height:15.75pt;"><td height="21" style="height:15.75pt;border-top:none;">S.G.(Density)</td><td style="border-top:none;border-left:none;">3.95-4.03</td></tr><tr height="22" style="height:16.5pt;"><td height="22" style="height:16.5pt;border-top:none;">Crystal System</td><td style="border-top:none;border-left:none;">Trigonal</td></tr></tbody></table><img src="https://sourcing-media.hktdc.com/product-original/Biron%C2%AE-20Lab-grown-20Blue-20Sapphire-20Square-20Shape/45e4ed2123564fd9a3e7f0aa70072ee4" style="width: 615px;" class="fr-fic fr-dib" data-productmediaid="45e4ed2123564fd9a3e7f0aa70072ee4" data-relationshipid="d157e310f4ce41d89b4c19d25494fd5c"><img src="https://sourcing-media.hktdc.com/product-original/Biron%C2%AE-20Lab-grown-20Blue-20Sapphire-20Square-20Shape/6cb26eb8600645dcbe1db35cf5204656" style="width: 621px;" class="fr-fic fr-dib" data-productmediaid="6cb26eb8600645dcbe1db35cf5204656" data-relationshipid="ffc136aa9149440e85feaff2e2174760"><img src="https://sourcing-media.hktdc.com/product-original/Biron%C2%AE-20Lab-grown-20Blue-20Sapphire-20Square-20Shape/33209ce09f5546dda1a3257234b11aad" style="width: 618px;" class="fr-fic fr-dib" data-productmediaid="33209ce09f5546dda1a3257234b11aad" data-relationshipid="e4c23bbaa5fe413a9a53ce0a27f869fb">

Whether it is a necklace or a bracelet covered with rubies, emeralds, sapphires and alexandrites, these bright stones continue to be loved for their beauty and the style they bring to jewellery pieces. &nbsp;Unfortunately, the rarity and price of many of these gemstones make their purchase out of reach for most people. Today, scientists are able to grow precious gems which are identical physically, chemically and optically to natural gems in a controlled laboratory environment which enables color to come out richer and more even.<img src="https://sourcing-media.hktdc.com/product-original/Created-20Emerald-20Rough-20Colombian-20Colour/f069fe5cab7f40cc967374905d223005" style="width: 561px;" class="fr-fic fr-dib" data-productmediaid="f069fe5cab7f40cc967374905d223005" data-relationshipid="c82f6a9fa7b34da4990d2bac31dba9d0">Lab-grown gemstones are the stunning, ethical and affordable alternative to earth-mined gems. By recreating the earth's natural process in a controlled laboratory environment, we are able to create rubies, emeralds, alexandrites, and sapphires that are higher in quality and more beautiful than most earth-mined equivalents and make them much more accessible to buyers. The more expensive and hard-to-find natural gems in jewellery, such as emerald, ruby, sapphire &amp; alexandrite are the favourite lab-grown stones. They are not gem imitations; lab-grown gemstones are real. They are grown in a laboratory, but are identical physically, chemically and optically to natural gems. An imitation gemstone, which is also man-made such as cubic Zirconia (CZ), does not follow nature’s recipe, so it is completely different physically, chemically and optically from the natural gem it copies. <img src="https://sourcing-media.hktdc.com/product-original/Created-20Emerald-20Rough-20Colombian-20Colour/788f1e0b7a2349bfb12a9d6901b8a941" style="width: 514px;" class="fr-fic fr-dib" data-productmediaid="788f1e0b7a2349bfb12a9d6901b8a941" data-relationshipid="022029f98d034f80ada8a1153ecdeedd">Biron® has lab-grown rough stones for emerald, ruby, blue sapphire, padparadscha and alexandrite.
