What is the ideal cut, color, and clarity one should choose for a 1 carat diamond?

For a dazzling 1 carat diamond, the ideal factors are an Excellent or Very Good cut for most visual impact, a G-H or above color for a bright appearance, and VS1 or VS2 clarity at the least for an eye-clean look.

Should one choose an eye-clean 1 carat diamond?

Yes, you should prioritize an eye-clean (gems without inclusions visible to the naked eye) 1 carat diamond while making a purchase. It ensures the best value and top-tier beauty. For instance, you will often find eye-clean but affordable 1 carat diamonds in SI1 or SI2 clarity grade.

What is the difference in the price of 1 carat natural diamond and 1 carat lab diamond?

On average, a 1 carat lab-grown diamond can cost 60–80% less than a natural one of similar quality. Both are real diamonds, but the difference lies in origin, rarity, and price point.

Why do some 1 carat diamonds cost more than others?

The price of any diamond depends on the 4Cs, i.e., cut, color, clarity, carat, shape, and lab certification. A well-cut 1 carat diamond with higher color and clarity grades and of round brilliant shape will naturally be more expensive than those with lower color, cut, clarity, and fancy shapes.

Are there hidden costs?

No. We offer transparent pricing with no hidden fees. The listed price includes certification, secure packaging, and insured shipping within the US.

What is the return policy on 1 carat diamonds?

At Fascinating Diamonds, every 1 carat loose diamond purchase is backed by a 30-day return policy. If you aren’t satisfied with your purchase, we will accept it within the given return window, provided the purchased item is in its original condition and with certification.

How long will it take to receive it?

For 1 carat diamond orders within the USA that are in stock, your package will be shipped within 3-5 business days. If you select paid fast shipping, it will reach you within 1-3 business days. If you choose a setting and customize the design, you will receive your order within 10-14 business days.
