Let’s Answer Your Lingering Questions

  • Are lab-grown diamonds as good as natural diamonds?

    Absolutely! Lab-grown diamonds are chemically and optically identical to natural diamonds. They possess the same exceptional qualities of clarity, color, and cut. The only difference is their clean origin, making lab-grown diamonds a more ethical and sustainable choice.Each lab -grown diamond is created in a conrolled environment,replicating the same natural processes that occur beneath the Earth's surface. Natural diamonds take millions of years to form deep within the Earth's crust and require significant effort and resources to mine. On the other hand, lab-grown diamonds can be produced in a matter of weeks, which significantly reduces the time and expenses involved in their creation resulting in lower prices. Mined diamonds require extensive environmental assessments, land excavation, and disruption of ecosystems. In contrast, lab-grown diamonds have a smaller environmental footprint, as their production occurs in a controlled environment with minimal impact on nature. The supply chain for natural diamonds involves mining, distribution, cutting, and polishing, each step adding to the overall cost. Lab-grown diamonds have a shorter and more direct supply chain, reducing the associated costs. Lab-grown diamonds offer more consistent quality and purity compared to mined diamonds, where the quality can vary significantly. This predictability allows for better pricing and cost control in the production of lab-grown diamonds.It's essential to note that while lab-grown diamonds are generally more affordable, they are not "cheap" in the sense of being of lower quality. Both natural and lab-grown diamonds can have excellent clarity, color, and brilliance, but lab-grown diamonds often offer better value for money due to their lower production costs.

  • How do I know the quality of the lab-grown diamonds you offer?

    Assessing the quality of a diamond involves considering the "Four Cs" (carat weight, cut, clarity, and color) along with other factors. Here's a step-by-step guide to help you evaluate the quality of a diamond: 1. Educate Yourself: Before purchasing a diamond, familiarize yourself with the Four Cs and their significance in determining a diamond's quality and value. There are numerous online resources and guides available to help you understand these factors. 2. Certificates and Grading Reports: Request a diamond grading report or certificate from a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI). These reports provide an unbiased and detailed assessment of the diamond's characteristics. 3. Carat Weight: Determine the size or carat weight of the diamond. Keep in mind that larger diamonds are generally rarer and more expensive, but the overall quality should also be considered. 4. Cut: Examine the diamond's cut grade, which directly impacts its brilliance and sparkle. Look for diamonds with excellent or very good cut grades for optimal light performance. 5. Clarity: Evaluate the diamond's clarity grade by examining it under proper lighting and using a loupe (a special magnifying tool). Aim for a diamond with minimal visible inclusions and blemishes, such as those in the SI (Slightly Included) range or higher. 6. Color: Assess the diamond's color grade by comparing it to a set of master stones under controlled lighting. Choose a diamond with a color grade that appears white or colorless to the naked eye, preferably in the near-colorless (D-F) range. 7. Shape: Consider the diamond's shape or cut style. Round brilliant cuts are the most popular, but other shapes like princess, emerald, oval, and others are available and may suit your preferences better. Remember, choosing a diamond is a personal decision, and it's crucial to find a balance between the Four Cs and your budget while prioritizing your preferences for size, sparkle, and overall appearance.

    Yes! We offer custom design services to help you create the perfect piece of jewelry within your desired budget. Simply provide us with the design and budget, and our expert team will work closely with you to craft a stunning piece that meets your specifications and budget.

    We offer a 15-day money-back guarantee. Simply contact our customer support team within 15 days of receiving your order, and we will guide you through the return process. Once we receive the returned item in its original condition, we will promptly issue a refund.

  • Can I consider purchasing a loose lab-grown diamond from you and having it set by a local jeweler?

    Yes.Purchasing a loose lab-grown diamond from us and having it set by a local jeweler offers you the chance of spending a lot less money on the stone ,while still being able to experiment with different settings in a brick and mortar store.

  • Can I request customized jewelry from you after I have purchased my loose lab-grown diamond?

    Yes,you can. For 90 days after your purchase,you can choose to create your dream jewelry with us instead of a local jeweler,in case the local prices for setting are still too prohibitive for you.

  • What is the process for growing a lab diamond?

    Lab-grown diamondLab-grown diamonds are created through two primary methods: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT). Both methods aim to replicate the natural diamond formation process, resulting in diamonds with similar physical and chemical properties as natural diamonds. Chemical Vapor Deposition (CVD) Method: The CVD method involves the following steps: a. Diamond Seed Preparation: A small diamond seed, usually a thin slice, is selected as the starting material. This seed acts as a foundation for the growth of the lab-grown diamond. b. Gaseous Precursors: A mixture of hydrocarbon gases (typically methane or other carbon-containing gases) and hydrogen is introduced into a chamber. c. Activation: The gases are then ionized or activated using a method such as microwave plasma or hot filament. This creates a highly reactive environment. d. Diamond Growth: The activated carbon and hydrogen atoms bond together on the diamond seed surface, gradually forming layers of carbon atoms. As more layers are added, the diamond grows in size. e. Cooling and Removal: The chamber is gradually cooled down, and the newly formed diamond is removed. The diamond is then cut and polished into the desired shape. High Pressure High Temperature (HPHT) Method: The HPHT method involves the following steps: a. Diamond Seed Preparation: Similar to the CVD method, a diamond seed is used as the starting material. b. High Pressure Environment: The diamond seed is placed in a pressurized environment along with a carbon source, typically graphite, and a metallic catalyst. c. High Temperature: The chamber is subjected to extremely high temperatures, usually above 1300 degrees Celsius (2372 degrees Fahrenheit). d. Diamond Growth: The combination of high pressure and temperature causes the carbon atoms from the graphite source to dissolve and deposit on the diamond seed, layer by layer. This process results in the growth of a larger diamond. e. Cooling and Removal: After the diamond has reached the desired size, the pressure is gradually released, and the diamond is allowed to cool. The grown diamond is then extracted from the chamber and subjected to cutting and polishing. Both CVD and HPHT methods can produce high-quality lab-grown diamonds with properties identical to natural diamonds.

  • What are the "Four Cs" of diamonds?

    The "Four Cs" of diamonds are a widely recognized grading system used to assess and describe the quality and value of a diamond. These four Cs are: Carat Weight: Carat is the unit of measurement used to weigh diamonds. One carat is equivalent to 200 milligrams. As the carat weight increases, the size of the diamond generally increases, which can affect its rarity and price. Cut: The cut of a diamond refers to the way it has been shaped and faceted. A well-cut diamond reflects light in a way that enhances its brilliance and sparkle. The cut grade is based on factors such as proportions, symmetry, and polish. Clarity: Clarity refers to the presence of internal or external flaws, known as inclusions and blemishes, respectively. These are formed during the diamond's natural growth process. The clarity grade ranges from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and/or blemishes visible to the naked eye). Color: The color grade of a diamond assesses the presence of any visible color. The most desirable diamonds are colorless, as they allow more light to pass through and result in greater brilliance. The color scale typically ranges from D (colorless) to Z (light yellow or brown). Beyond Z, diamonds are considered "fancy" and display more intense colors, such as blue, pink, or yellow. By considering these four Cs in combination, buyers and professionals in the diamond industry can evaluate and compare diamonds, ensuring they make informed choices about their purchases. Each of the four Cs plays a crucial role in determining the overall quality and value of a diamond.

  • What are the advantages of custom designed rings?

    Personalization: Custom-designed rings offer a high level of personalization, allowing customers to create a piece of jewelry that truly reflects their individual style and preferences. They can choose the metal, gemstones, setting style, and other design elements, ensuring a unique and meaningful piece. Perfect Fit: With custom-designed rings, customers can get a perfect fit that complements their finger size and shape. This helps in ensuring comfort and prevents the ring from slipping off or feeling too tight. Quality Craftsmanship: Custom-designed rings are often crafted by skilled artisans who pay meticulous attention to detail. This results in a higher level of craftsmanship and overall quality compared to mass-produced ready-made ring mountings. Exclusive Designs: Customers can have exclusive designs created for them, making their jewelry stand out from mass-produced options. This exclusivity adds sentimental value and makes the piece even more special. Involvement in the Design Process: Clients get to actively participate in the design process, collaborating with jewelers to bring their vision to life. This involvement fosters a sense of connection to the piece and enhances the overall buying experience. Unique Gemstone Selection: Those who opt for custom-designed rings can select from a wide range of gemstones, including rare and exotic options. This opens up a world of possibilities beyond the limited choices typically available in ready-made rings. Customized Engravings: Custom rings offer the option of personalized engravings, allowing customers to add names, dates, or meaningful messages that hold sentimental value. Timeless Appeal: Custom-designed rings are often timeless in style and can be passed down through generations as heirlooms, thanks to the thoughtful design and craftsmanship. Flexibility in Budget: Contrary to the misconception that custom-designed rings are always expensive, customers have the flexibility to choose materials and design elements that fit their budget. Jewelers can suggest alternatives to achieve the desired look while staying within the client's financial constraints.
