Questions and answers

Which pair looks bigger in the ear?
The 2.0 ct pair. Each earring holds roughly 1 ct versus about 0.5 ct in the Blue Nile pair, so the stones read noticeably larger.
Is the Blue Nile pair worth the extra $880?
Only if brand backing and the stated F-G/VS2-SI1 grades matter more to you than size. On paper the eBay pair gives twice the weight for less than half the price.
Which has better diamond grades?
The Blue Nile page claims F-G color and VS2-SI1 clarity, but its own listing shows J and I2. The eBay pair is IGI certified at E-F/VS2-SI1 per the title, though its page says G-H/SI. Ask for the actual certificate before buying either.
Do both use screw backs?
Yes. Both are four-prong studs with screw backs. Reviewers of both mention back issues: hard to grip on the Blue Nile pair, one misaligned screw on the eBay pair.
Which is better for everyday wear?
The 1 ct Blue Nile pair is lighter and less likely to catch on clothing. The 2.0 ct pair is better for evenings and events where you want visible size.
Are the diamonds real?
Both use lab-grown diamonds, which are real diamonds with the same physical properties as mined ones. The eBay pair includes IGI certificates; the Blue Nile listing does not mention a report.
