What Is Moissanite?<\/h2>\n

Moissanite is a distinct <\/span>gemstone <\/span>from diamond<\/span>. Originally discovered in a meteor crater in 1893,\u00a0<\/span>it<\/span> is composed of silicon carbide. Natural moissanite is extremely rare, so all moissanite\u00a0<\/span>used in jewelry<\/span> today is lab-created.<\/span><\/span>\u00a0<\/span><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.24.0″ _module_preset=”default” text_font_size=”16px” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]

Is Moissanite a Real Diamond?<\/h2>\n

While moissanite is sometimes chosen as an alternative to diamonds\u00a0<\/span>for<\/span> its brilliance and lower cost, it is not a diamond, nor is it considered a diamond simulant. It has its own set of unique characteristics.<\/span><\/span>\u00a0<\/span><\/p>\n

Lab-grown diamonds are actual diamonds\u2014chemically, <\/span>physically<\/span> and optically identical to mined diamonds. The only real difference is their origin: lab-grown diamonds are produced in controlled, high-tech laboratories using advanced methods. Learn more about<\/span> the<\/span> specific characteristics<\/span> <\/span>of lab-grown diamonds<\/span> in our <\/span>buying <\/span><\/a>guide<\/a>.<\/span><\/span>\u00a0<\/span><\/span><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.24.0″ _module_preset=”default” text_font_size=”16px” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]

Moissanite vs. Diamond Sparkle<\/h2>\n

The most noticeable difference between moissanite and a lab-grown diamond is how they handle light. This comes down to their brilliance and fire. Learn more about diamond brilliance and fire and why they matter for your purchase in our guide.<\/span>\u00a0<\/span><\/p>\n

Lab-grown diamonds display exceptional brilliance<\/span>, with a refractive index of 2.42. This high refractivity allows them to reflect abundant white light, giving them that classic, crisp sparkle.<\/span>\u00a0<\/span><\/p>\n

Moissanite has an even higher refractive index, ranging from 2.65 to 2.69. This means it is technically more brilliant than a diamond.<\/span>\u00a0<\/span><\/p>\n

Fire is where the visual difference between the two becomes most apparent. Moissanite is “doubly refractive,” meaning it splits light into two rays, creating a fiery, rainbow-like effect. Diamonds, on the other hand, are “singly refractive.” While they still produce fire, it\u2019s more evenly balanced with their white light brilliance. In a moissanite vs diamond comparison, moissanite will show more colorful flashes, whereas a lab-grown diamond will display a more classic balance\u00a0of white and colored sparkle.<\/span>\u00a0<\/span><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.0″ _module_preset=”default” width=”837.1%” custom_margin=”-31px|auto||auto||” custom_padding=”47px|||||”][et_pb_column _builder_version=”4.24.0″ _module_preset=”default” type=”4_4″][et_pb_image src=”https:\/\/www.borsheims.com\/blog\/wp-content\/uploads\/2025\/09\/CLRTY-R150RB-Y-A-jpeg.jpg” _builder_version=”4.24.0″ _module_preset=”default” hover_enabled=”0″ sticky_enabled=”0″ alt=”Clarity Diamond Signature Lab-Grown Round Diamond Solitaire Engagement Ring in Yellow Gold” title_text=”CLRTY-R150RB-Y-A-jpeg” align=”center” width=”67.6%”][\/et_pb_image][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.0″ _module_preset=”default” custom_margin=”-93px|auto||auto||”][et_pb_column _builder_version=”4.24.0″ _module_preset=”default” type=”4_4″][et_pb_text _builder_version=”4.24.0″ _module_preset=”default” text_font_size=”16px” hover_enabled=”0″ sticky_enabled=”0″]

Is Moissanite as Durable as a Diamond?<\/span><\/h2>\n

When choosing a stone for everyday wear, such as an engagement ring, durability is a key factor. The Mohs Scale of Hardness measures a mineral’s resistance to scratching.<\/span>\u00a0<\/span><\/p>\n

Diamonds, whether natural or lab-grown, are the hardest known mineral, scoring a perfect 10 on the Mohs scale. <\/span>Their exceptional hardness makes them extremely resistant to scratches and abrasions, making them a perfect choice for a lifetime of wear.<\/span>\u00a0<\/span><\/p>\n

Moissanite is the second-hardest gemstone used in jewelry, scoring 9.25 on the Mohs scale. While not as hard as a diamond, it\u2019s still more scratch-resistant\u00a0than other popular gemstones like sapphires and rubies (which score a 9). <\/span>You can be confident that a moissanite stone will stand up to the rigors of everyday life. <\/span>\u00a0<\/span><\/p>\n[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}” custom_margin=”-9px|auto||auto||”][et_pb_column type=”4_4″ _builder_version=”4.24.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.24.0″ _module_preset=”default” text_font_size=”16px” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]
