The worth and quality of your diamond are guaranteed by a diamond certificate from the International Gemological Institute (IGI), American Gem Society (AGS), or Gemological Institute of America (GIA). The three gold standards for diamond grading are GIA, AGS, and IGI. Their reports go into detail about each diamond's salient features.

The Global Gemological Research Association Institute specially offers the reports for our Moissanite Gemstone. Our selected Moissanite Stone or Moissanite Jewelry comes with a GRA Certificate.

The Gemological Institute of America's (GIA) industry-grade criteria are known as the Four Cs: Carat (size), Color, Clarity, and Cut. These characteristics are used to specifically grade each diamond.

A diamond's cut determines how effectively it returns light to the viewer's eye. A well-cut diamond appears brilliant and fiery, while poorly cut stones look dark and lifeless. Well-cut diamonds often appear larger than stones of the same carat weight.

Every loose diamond and diamond engagement ring that we send comes with an independent lab report from the GRA, GIA, AGS, or IGI. A certified gemologist can review this report and compare it to the special qualities of your diamond.

Natural moissanite is extremely rare and found in limited quantities (e.g., meteorites). Most moissanite sold today is lab-created, offering ethical and affordable alternatives to diamonds.

Moissanite has a higher refractive index, giving it more "fire" (colorful sparkle) than diamonds. It is slightly less hard (9.25 vs. 10 on the Mohs scale) but is highly durable for everyday wear.

Yes. Lab-created moissanite typically costs 80-90% less than diamonds of similar size and quality.

Moissanite is highly scratch-resistant and retains its brilliance indefinitely with proper care. Clean it regularly with mild soap and water.

Lab-grown moissanite avoids mining-related environmental and ethical concerns, making it a sustainable choice.

Yes, moissanite rings are worth it! They are affordable, durable (9.25 Mohs), eco-friendly, and have brilliant sparkle. Unlike diamonds, moissanite has more rainbow fire and is lab-created, making it an ethical choice.

Absolutely! Many people choose moissanite for engagement rings due to its beauty, durability, and affordability.

Yes, moissanite rings can last a lifetime, just like diamonds. Moissanite is highly durable, ranking 9.25 on the Mohs hardness scale, second only to diamonds (which rank at 10). This makes it scratch-resistant, chip-resistant, and suitable for everyday wear.

You can clean moissanite with warm water, mild soap, and a soft brush. Jewelry cleaners and ultrasonic cleaners are also safe to use.

The choice between lab-grown and natural diamonds from Caratina hinges on your goals. Both types are conflict-free and have different diamond gradings. Lab-grown diamonds are a great option for those looking to stretch their budget. You can get up to 30% more diamond size at the same price point. On the other hand, natural diamonds are remarkable products of nature and the classic choice.

Lab-grown diamonds, despite being produced within a laboratory setting, are most definitely real diamonds. Scientists initiate the process with a diamond seed, which is a tiny fragment of chemicals. Subsequently, this seed is subjected to specific temperatures and pressures. These conditions mimic those found deep beneath the Earth's surface, allowing the diamond to grow in a similar manner. As the diamond grows, a carbon coating plays a crucial role in facilitating its crystallization process.

Lab-grown and natural diamonds are identical but differ in origin, rarity, and price. Lab diamonds are cheaper and eco-friendly, while natural ones hold value better.

Yes, Caratina will provide an appraisal and/or a laboratory certificate.

Yes, lab-grown diamonds are generally considered more ethical than natural diamonds. They are conflict-free, as they don’t involve harmful mining practices, exploitative labor, or environmental destruction.

Not at all! Lab-grown diamonds are exactly as robust and scratch-resistant as mined diamonds since they share all of their physical and chemical characteristics, so they will never cloud.

Common chemicals in perfume, hair spray, soap, and lotion will make rhodium tarnish permanently. Stay away from chlorine and other bleaches, including swimming pools. Rhodium-plated jewelry will turn quickly if it meets those chemical substances.

For regular cleaning, it is recommended that you use our signature jewelry polishing cloth that is infused with a special jewelry cleaner. You can also use a soft, 100% cotton cloth. It is recommended that you have one cleaning cloth for gold and a separate one for silver. DO NOT use silver liquid cleaner to clean rhodium-plated jewelry. It is too harsh and can dull or harm the rhodium plating.

Maintain the beautiful shine by polishing gold plated and rose gold plated jewelry with a soft cloth. Dampen the cloth with lukewarm soapy water and rub the cloth gently on jewelry. Rinse with clean water and pat dry with a soft cloth. If jewelry requires extra cleaning, soak it for 5 to 10 minutes before rubbing.

Do not use silver polishing liquids, silver dips, ultrasonic cleaning or a tumbler.

To keep tarnishing to a minimum, it is strongly advised that you store your silver jewelry in a dry and air-tight area, such as a jewelry box or zip-lock bag. Keep your jewelry pieces from rubbing against other items when you are not wearing them. Although silver jewelry is scratch resistant, it isn't scratch proof.
