Why Buy Diamond from GemSelect?

FAQs

What are loose diamonds, and why should I consider buying them?

Loose diamonds are individual diamond stones that are not yet set in jewelry. They provide greater flexibility, allowing buyers to choose their preferred setting, style, and design. Purchasing a loose diamond also gives you the opportunity to inspect its quality based on factors like clarity, color, and carat weight before it is mounted.

Where can I find certified loose diamonds for sale?

You can find certified loose diamonds at reputable online stores and authorized loose diamond dealers. Make sure to look for GIA loose diamonds, as GIA certification is a trusted standard for assessing a diamond's quality, including its cut, color grading, and clarity.

How do I determine the best loose diamond shapes and cuts?

Choosing the right shape and cut is important for maximizing a diamond's brilliance. Popular loose diamond shapes include round, princess, cushion, and oval. Each shape has its unique appeal, while the cut impacts the stone’s sparkle. A good loose diamond buying guide can help you understand the various options available.

Are natural loose diamonds better than lab-grown options?

Natural loose diamonds are formed over millions of years, while lab-grown diamonds are created in controlled environments. Both can be of high quality, but natural diamonds are often valued more for their rarity. When purchasing, ensure the stone is certified for authenticity, especially if you want a conflict-free loose diamond.

What should I know about loose diamond prices and wholesale options?

The price of a loose diamond depends on its carat weight, clarity, color grading, and cut. If you’re looking to save, consider loose diamond wholesale options, where you can find stones at lower prices. Wholesale purchases often provide better value, especially for bulk orders or custom jewelry projects.

How can I ensure I’m buying a high-quality loose diamond online?

To ensure you’re buying a high-quality stone, choose a reputable online loose diamond store that offers GIA certified loose diamonds. Review the diamond’s specifications, including its clarity, cut, and color grading, and ask for detailed certification documents.

Would have bought an indigo and selenite, but neither listed. But, you do offer quite a large assortment otherwise.

I like the site, it's easy to navigate. There are sometimes items I'm looking for that aren't there, but mostly I can find what I need.
