Many think they\u2019re the same stone. Some even believe one is just a cheaper version.<\/p>\n<p>The truth is, these two stones differ in origin, structure, and market suitability. Read on as this\u00a0guide will clear up all the confusion.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong><b>An<\/b><\/strong><strong><b>\u00a0Overview<\/b><\/strong><strong><b>\u00a0of Zircon<\/b><\/strong><\/h2>\n<p>Zircon is a naturally occurring gemstone formed within the Earth\u2019s crust over millions of years. It has long held a place in gem history, but its use in modern jewelry is limited.<\/p>\n<h3>1.\u00a0<strong><b>Naturally Mined Gemstone<\/b><\/strong><\/h3>\n<p>Zircon is mined primarily in Australia and Cambodia.\u00a0Each stone formed over geological time periods. Its origin gives it an authentic, earth-derived appeal.<\/p>\n<h3>2.\u00a0<strong><b>Mainly Composed of Zirconium Silicate<\/b><\/strong><\/h3>\n<p>Zircon\u2019s chemical makeup is\u00a0mainly\u00a0zirconium silicate (ZrSiO4). The\u00a0composition remains stable for millions of years.<\/p>\n<h3>3.\u00a0<strong><b>Has a Mohs Scale of 6-7.5<\/b><\/strong><\/h3>\n<p>Zircon measures between 6 and 7.5 on the <a href=\"https:\/\/www.starharvestcn.com\/be\/News\/blog\/what-is-the-mohs-scale.html\/\" target=\"_blank\" rel=\"noopener\">\u0448\u043a\u0430\u043b\u0435 \u0446\u0432\u0451\u0440\u0434\u0430\u0441\u0446\u0456 \u041c\u043e\u0441\u0441\u0430<\/a>.\u00a0It is a medium-hard gemstone.<\/p>\n<h3>4.\u00a0<strong><b>Naturally-Occurring Radioactive Material<\/b><\/strong><\/h3>\n<p>Most zircon contains trace radioactive elements\u00a0including uranium and thorium.<\/p>\n<h3>5.\u00a0<strong><b>Comes in Different Colors<\/b><\/strong><\/h3>\n<p>Zircon shows up in many natural colors. However, achieving consistent color quality is challenging, as shades vary from stone to stone. Heat treatment can enhance or stabilize the color, but results are not always uniform.<\/p>\n<h3>6.\u00a0<strong><b>Generally Not Used for Jewelry<\/b><\/strong><\/h3>\n<p>Due to\u00a0its moderate hardness and radiation concerns, zircon is less favored in mainstream jewelry production. It is typically reserved for\u00a0collector\u00a0or decorative pieces where natural authenticity outweighs wearability.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong><b>An Overview of <\/b><\/strong><strong><b>Cubic Zirconia<\/b><\/strong><\/h2>\n<p>Cubic zirconia (CZ) was developed in laboratories during the 1970s\u00a0to emulate the look of diamonds. It offers\u00a0consistency, safety, and broad creative flexibility for jewelry brands.<\/p>\n<h3>1.\u00a0<strong><b>Man-Made Gemstone<\/b><\/strong><\/h3>\n<p>Cubic zirconia is fully synthetic. This means uniform quality, clarity, and size availability, important factors for jewelry brands to maintain standardized collections.<\/p>\n<h3>2.\u00a0<strong><b>Mainly Composed of Zirconium Dioxide<\/b><\/strong><\/h3>\n<p>Unlike natural zircon, cubic zirconia mainly consists of zirconium dioxide(ZrO2).<\/p>\n<h3>3.\u00a0<strong><b>Has a Mohs Scale of 8-8.5<\/b><\/strong><\/h3>\n<p>Cubic zirconia rates 8 to 8.5 on the Mohs hardness scale. It resists scratches and retains polish well.<\/p>\n<h3>4.\u00a0<strong><b>Extremely-Low Level Radiation<\/b><\/strong><\/h3>\n<p>Cubic zirconia contains virtually no radioactive material. Any trace amounts present are far below safety concerns. This makes it much safer than natural zircon.<\/p>\n<h3>5.\u00a0<strong><b>Come in Different Colors<\/b><\/strong><\/h3>\n<p>Cubic zirconia can be made in almost any color. Clear stones that mimic diamonds are most common. Other varieties like pink, blue, and yellow are popular too.<\/p>\n<h3>6.\u00a0<strong><b>Widely Used for Jewelry<\/b><\/strong><\/h3>\n<p>Cubic zirconia resists scratching, maintains its shine over time, and poses no safety concerns for wearers. Its affordability, brilliance, and size\/color availability make this jewelry gemstone a go-to option for brands focusing on accessible or trend-driven jewelry collections.
