FAQs

What are loose blue diamonds?

Loose blue diamonds are unmounted, natural gemstones known for their stunning blue color and rarity. These gems are often used to create custom jewelry, such as engagement rings, or kept as investment pieces.

Are GIA-certified blue diamonds better?

Yes, GIA-certified blue diamonds are highly recommended as they guarantee the gemstone's authenticity, quality, and details like cut, clarity, and carat weight. Choosing GIA-certified loose blue diamonds ensures you’re purchasing a genuine and valuable stone.

What makes fancy blue diamonds unique?

Fancy blue diamonds are prized for their vivid blue color and are rarer than traditional diamonds. Their unique hues, combined with exceptional clarity and cuts, make them a favorite choice for collectors and jewelry designers.

Can I use loose blue diamonds for engagement rings?

Absolutely! Loose blue diamonds are perfect for custom engagement rings. Their natural beauty and versatility allow you to choose the ideal cut and setting for a unique and meaningful design.

How do I care for my loose blue diamonds?

To maintain the brilliance of your loose blue diamonds, clean them regularly with a soft cloth and mild soap. Avoid exposing them to harsh chemicals and store them separately to prevent scratches on the surface.

Are loose blue diamonds a good investment?

Yes, loose blue diamonds, especially rare or GIA-certified stones, are considered excellent investments due to their rarity and increasing market demand. Their natural beauty and timeless appeal make them valuable assets.

What factors determine the value of a loose blue diamond?

The value of a loose blue diamond depends on its color intensity, clarity, cut quality, and carat weight. Rare fancy blue diamonds or those with vivid blue hues often command higher prices.

Are there different cuts available for loose blue diamonds?

Yes, loose blue diamonds come in various cuts, including round, princess, emerald, and cushion. Each cut enhances the stone's brilliance and highlights its natural blue color.

What is the difference between natural and treated blue diamonds?

Natural blue diamonds derive their color from boron within the stone, while treated diamonds undergo processes like irradiation to achieve a blue hue. Natural blue diamonds, such as those in our collection, are more valuable and sought after.

Where can I buy high-quality loose blue diamonds?

You can find high-quality loose blue diamonds, including rare fancy blue diamonds and GIA-certified options, from trusted gemstone dealers. Look for vendors offering a wide selection of cuts, sizes, and colors to suit your needs.

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

Site is easy to navigate - details on cut, polish, and finish work and techniques were helpful. 3d view or wireframe diagram of stones would be nice.

I was looking for a small gift for a friend- the process is the same as every other time and was very simple, and she even got her gift early! On the downside, there's no way to easily keep track of multiple Shipping Addresses, so if I want to send a gift to Friend A and to Friend B, I have to overwrite everything and it's a fair bit clunky in that regard.
