If you are looking for an <a href=\"https:\/\/fashiongold.lt\/kategorija\/suzadetuviu-ziedai\/\" target=\"_self\" rel=\"noopener noreferrer\">engagement ring<\/a>, planning to invest in gemstones, or simply interested in jewelry, you will find all the most important information in one place.<\/p>\n<p>In this article, we will discuss what a diamond is, the differences between natural, lab-grown, and artificial diamonds, how to distinguish them, the main diamond quality criteria, how their price is determined, what certificates are available, and how to properly care for diamonds. You will learn why it is important to know these differences so you can make the right decision when choosing a diamond \u2013 whether for a piece of jewelry or as an investment.<\/p>\n<p><strong>Important:<\/strong> From the very beginning, we clearly distinguish the terms \u2013 a <em>natural diamond<\/em> is formed in nature, a <em>lab-grown diamond<\/em> is grown in a laboratory but is identical to a natural one, and an <em>artificial diamond<\/em> (imitation) is a stone that only looks like a diamond but does not possess its properties (e.g., moissanite or cubic zirconia).<\/p>\n<p><strong>Next, we will discuss:<\/strong><\/p>\n<ul>\n<li>What a diamond is and what makes it special<\/li>\n<li>Key differences between natural, lab-grown, and artificial diamonds<\/li>\n<li>How to distinguish these types<\/li>\n<li>Diamond quality criteria (4Cs)<\/li>\n<li>Certificates and their significance<\/li>\n<li>Diamond prices and investment aspects<\/li>\n<li>Care tips<\/li>\n<li>Frequently Asked Questions<\/li>\n<\/ul>\n<h2>What is a diamond?<\/h2>\n<p>A diamond is one of the oldest and hardest minerals on Earth. This gemstone fascinates not only with its brilliance but also with its unique properties that make it special in jewelry. It is also important to mention that the cutting and shape of diamonds determine their sparkle and value.<\/p>\n<p>Gemstones can be chosen from various types, and their quality, certification, and exceptional value provide jewelry not only with beauty but also with investment value. The rarity of the gemstone, its symbolic meaning, and high quality further emphasize its importance in jewelry. It is important to know that brilliants are diamonds of an exceptional cut, characterized by special sparkle and often considered the highest quality diamonds in jewelry.<\/p>\n<p><strong>Transition sentence:<\/strong> Next, we will discuss how diamonds differ from other gemstones and what types exist.<\/p>\n<h2>How does a diamond differ from other gemstones?<\/h2>\n<p>Diamonds are considered special because their hardness on the Mohs scale reaches 10 points. This means they are resistant to daily wear.<\/p>\n<p>In addition, diamonds stand out for their value, purity, and unique properties, which clearly distinguish them from other gemstones.<\/p>\n<h2>How to distinguish a natural, lab-grown, and artificial diamond?<\/h2>\n<p>One of the most frequent questions is how to recognize whether a diamond is natural, lab-grown, or artificial (imitation)?<\/p>\n<ul>\n<li><a href=\"https:\/\/fashiongold.lt\/en\/natural-diamonds\/\" target=\"_self\" rel=\"noopener noreferrer\"><strong>Natural diamond<\/strong><\/a> \u2013 formed in nature over millions of years, it has a unique internal structure and inclusions that are impossible to replicate exactly in a laboratory.<\/li>\n<li><a href=\"https:\/\/fashiongold.lt\/en\/grown-diamonds\/\" target=\"_self\" rel=\"noopener noreferrer\"><strong>Lab-grown diamond<\/strong><\/a> \u2013 grown in a laboratory, but has the identical chemical composition, crystal structure, and properties as a natural diamond. They cannot be distinguished by the naked eye \u2013 special equipment and certificates are required for that.<\/li>\n<li><strong>Artificial diamond (imitation)<\/strong> \u2013 this is a stone that only looks like a diamond but does not have its properties. The most common examples are: moissanite (a synthetic gemstone visually similar to a diamond but with a different chemical composition) and cubic zirconia (CZ, a synthetic crystal visually resembling a diamond but much softer and cheaper).<\/li>\n<\/ul>\n<p><strong>Important:<\/strong> Only certificates (e.g., <a href=\"https:\/\/fashiongold.lt\/en\/patarimai\/how-to-read-a-gia-certificate\/\" target=\"_self\" rel=\"noopener noreferrer\">GIA<\/a>, HRD, IGI) and professional expertise can reliably determine a diamond&#8217;s origin.<\/p>\n<h2>What is the difference between a diamond and a brilliant?<\/h2>\n<p><img decoding=\"async\" src=\"https:\/\/fashiongold.lt\/wp-content\/uploads\/2026\/01\/3917b5af-6377-40a8-844e-733cf5077dfa.png\" alt=\"On the left side, a raw diamond is shown, on the right \u2013 a polished brilliant, illustrating the difference between a diamond and a brilliant\" \/><\/p>\n<p><strong>Brilliant<\/strong> \u2013 this is a diamond processed with a round cut with 57\u201358 facets, which highlights the stone&#8217;s brilliance and beauty. Thus, every diamond can become a brilliant if it is given the proper shape and cut.<\/p>\n<p>Various diamond shapes also exist \u2013 such as oval, square, or heart-shaped cuts, which influence the appearance and value of the diamond.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/fashiongold.lt\/wp-content\/uploads\/2026\/01\/fca59ad9-fbe2-4842-a4fe-a9427b57e358.png\" alt=\"Four diamonds of different shapes \u2013 cushion, heart, round brilliant, and pear cut \u2013 arranged in a row on a white background, clearly visible cut facets\" \/><\/p>\n<h2>Natural diamonds<\/h2>\n<h3>How natural diamonds are formed<\/h3>\n<p>Natural diamonds form deep within the Earth over millions, and sometimes even billions, of years. Extremely high pressure and temperature cause a simple carbon atom structure to turn into one of the hardest minerals on Earth. Due to this unique process, a natural diamond is not just a gemstone but a true miracle of nature.<\/p>\n<h3>Where natural diamonds are found<\/h3>\n<p>These stones are found in very limited deposits \u2013 mainly in Africa, Russia, Canada, and Australia. Since their resources are limited and decrease over time, natural diamonds are becoming increasingly valued.<\/p>\n<h3>What makes natural diamonds special<\/h3>\n<p>Furthermore, a natural diamond is unique \u2013 each has its own internal structure, inclusions, or color nuances that become like a &#8220;fingerprint&#8221; of the stone. This means that no two identical natural diamonds exist.<\/p>\n<p>Natural diamonds not only symbolize luxury and eternal love but are also often considered an investment, as high-quality stones with international certificates maintain or even increase their value.<\/p>\n<h2>Lab-grown diamonds<\/h2>\n<p><img decoding=\"async\" src=\"https:\/\/fashiongold.lt\/wp-content\/uploads\/2026\/01\/4a2b7995-143e-4ffe-a3a8-f154935694de.png\" alt=\"Lab-grown diamonds are grown over several weeks by replicating the natural process in a laboratory\" \/><\/p>\n<h3>How lab-grown diamonds are grown<\/h3>\n<p>Lab-grown diamonds (<em>Lab Grown Diamonds<\/em>) are grown over several weeks by replicating the natural process. They have the same chemical composition, crystal structure, color, and clarity as natural diamonds; only their origin is not deep within the Earth but in special laboratories.<\/p>\n<p>There are two main growing technologies:<\/p>\n<ul>\n<li><strong>HPHT (High Pressure High Temperature)<\/strong> \u2013 natural conditions (high temperature and pressure) in which a diamond forms are replicated.<\/li>\n<li><strong>CVD (Chemical Vapor Deposition)<\/strong> \u2013 a diamond is &#8220;grown&#8221; from a gas plasma, layer by layer, until a crystal is formed.<\/li>\n<\/ul>\n<h3>Certification of lab-grown diamonds<\/h3>\n<p>Lab-grown diamonds are also certified in IGI or HRD laboratories, so their quality is determined according to the same criteria as natural ones. Visually, it is impossible to distinguish them from natural ones with the naked eye \u2013 this can only be done by specialized equipment.<\/p>\n<h3>Advantages of lab-grown diamonds<\/h3>\n<p>These diamonds are considered more environmentally friendly because their extraction does not require mass mining, which impacts nature. Eco-friendliness and ethical choice are among the main reasons why lab-grown diamonds are rapidly gaining popularity among young buyers.<\/p>\n<h3>&#8220;Artificial diamonds&#8221; \u2013 a common mistake<\/h3>\n<p>Often people call laboratory-grown diamonds &#8220;artificial diamonds,&#8221; but this is not an accurate description. A lab-grown diamond is a real diamond \u2013 having the identical chemical composition, crystal structure, optical and physical properties as a natural diamond. The only difference is its origin is a laboratory, not nature.<\/p>\n<p><strong>Artificial diamond (imitation)<\/strong> \u2013 these are synthetic or imitation stones that only look similar to a diamond but do not have its properties. For example:<\/p>\n<ul>\n<li><strong>Moissanite<\/strong> \u2013 a very sparkly synthetic gemstone, visually similar to a diamond but with different chemical properties.<\/li>\n<li><strong>Cubic Zirconia (CZ)<\/strong> \u2013 a popular imitation, a synthetic crystal visually resembling a diamond but much softer and cheaper.<\/li>\n<li>Other synthetic crystals or glass imitations.<\/li>\n<\/ul>\n<p>Therefore, using the term &#8220;artificial diamond&#8221; for a lab-grown diamond is a mistake because it misleads the buyer. In international practice, they are called Lab Grown Diamonds, Laboratory-Created Diamonds, or Man-Made Diamonds \u2013 all these terms mean they are real diamonds, just obtained in a different way.<\/p>\n<p>\u2705 Important for the buyer to know: if you see the phrase &#8220;artificial diamond&#8221; in documents or a seller&#8217;s description, always clarify whether it refers to a lab-grown real diamond or a synthetic imitation. This will help avoid a false impression and ensure you get what you are looking for.<\/p>\n<h2>Certified diamonds<\/h2>\n<p>Certified diamonds are evaluated in independent laboratories such as GIA (Gemological Institute of America), HRD (Hoge Raad voor Diamant \u2013 Antwerp Diamond Council), or IGI (International Gemological Institute). Quality is determined by four criteria \u2013 color, clarity, weight (carats), and cut. A certificate ensures that the stone is real and has a clear market value. The GIA certificate is considered the most reliable international standard.<\/p>\n<p>Interestingly, the same diamond may be evaluated differently in different laboratories \u2013 for example, a G color in one place might become an H color, and VS1 might become VS2. This is normal, as each laboratory applies its own standards.<\/p>\n<p>\ud83d\udc49 <strong>Tip:<\/strong> rely on the GIA certificate as the most reliable source, but don&#8217;t forget to evaluate the diamond in person \u2013 its sparkle, proportions, and overall impression.<\/p>\n<h3>Lithuanian Assay Office \u2013 a guarantee of reliability<\/h3>\n<p>In Lithuania, international certificates (GIA, HRD, IGI) are not mandatory, but every diamond must be checked at the Lithuanian Assay Office, which evaluates according to CIBJO (World Jewellery Confederation) standards. Since they often check stones that are already set, the evaluation is stricter and may differ from international laboratories, allowing up to a 20% margin of error. Such differences are normal, as this institution primarily protects the buyer&#8217;s interests.<\/p>\n<p>Therefore, a diamond purchased in Lithuania has a double guarantee \u2013 an international certificate and confirmation from the Assay Office, providing greater security and transparency.<\/p>\n<h2>Diamond shape<\/h2>\n<h3>Most popular diamond shapes<\/h3>\n<p>A diamond&#8217;s shape can be round, oval, princess (square), emerald, or heart. You can also choose the diamond shape you like best based on your personal preferences.<\/p>\n<p>The popularity of these shapes depends on fashion trends, and they are evaluated based on quality criteria such as symmetry, proportions, and light reflection.<\/p>\n<p>A properly chosen diamond shape is extremely important for rings, especially engagement or wedding rings.<\/p>\n<h2>Diamond color<\/h2>\n<h3>Diamond color scale<\/h3>\n<p>Color determines the stone&#8217;s value \u2013 from D (whitest) to Z (with a yellowish tint).<\/p>\n<p>It is also important to mention that all color nuances, such as hue, tone, and saturation, determine the stone&#8217;s beauty and value.<\/p>\n<h2>Diamond clarity<\/h2>\n<h3>Diamond clarity classification<\/h3>\n<p>Clarity (the clarity indicator) describes how many inclusions a stone has. The fewer there are, the more valuable the diamond.<\/p>\n<h2>Diamond weight &#8211; carats<\/h2>\n<h3>Carat \u2013 the unit of diamond weight<\/h3>\n<p>The weight of brilliants must be coordinated with the budget, as each additional carat (1 carat = 0.2 grams) significantly increases the price. A carat is the unit of weight used to measure diamonds.<\/p>\n<h2>Diamond prices<\/h2>\n<p>Diamond prices can differ tenfold depending on whether they are natural or lab-grown. Size (carat) is one of the main factors determining diamond price differences. The price of each diamond is determined according to four criteria \u2013 the 4Cs: color, clarity, cut, and carats. The 4Cs is the international diamond quality evaluation standard.<\/p>\n<p>The price of a 1ct brilliant is often higher than the price of a 1 carat diamond because a brilliant is a specially processed diamond whose cut shape highlights the stone&#8217;s beauty, clarity, and color.<\/p>\n<p>Investing in diamonds should be done according to your needs and budget, but it is most worthwhile to choose brilliants with a GIA or other recognized certificate, as this ensures their authenticity and quality.<\/p>\n<p><strong>The comparison table will help you quickly understand the main differences between a natural, lab-grown, and artificial (imitation) diamond \u2013 this is especially relevant when choosing a diamond for jewelry or investment.<\/strong><\/p>\n<h3>Comparison: Natural Diamond
