I would like to buy a pair of black diamond earrings. I found these on invaluable.com: https://www.invaluable.com/auction-lot/a-pair-of-solitaire-black-diamond-stud-earrings-9ad4fc491a Do you think these are genuine black diamonds? Price estimate is AUD 1400 – 1800. The auction finished a few hours ago. So, I missed this pair but there are other earrings that are almost an exact match. Authenticity issue is what bothers me…
Dear Ongesa,
No doubt, these are genuine black diamonds. They have all the typical visual characteristics a black diamond would normally have. Thus, no problem with that.
Let me elaborate on this further. The price is unreasonably high for this pair of earrings. This is a rather simple piece of jewelry. Color treated black diamonds are pretty cheap. It seems that the seller hasn’t mentioned anything about treatment in the description, but rest assured that they are color enhanced.
You can get black diamonds like these (or even better) at a price of $60 – $70 per 2.2 to 2.4 carat diamond (on ebay, for example). Mounting settings would cost you another $100 or so + 2 backs at roughly $ 20 per piece (this is what I found in no time; probably you could find an even better deal by investing some time).
So, let’s do the math: (70 x 2) + 100 + 40 + shipping (let’s say another $20) = $300. Mounting is very easy in this case. It should take an experienced jeweler less than 30 minutes. The cost depends on how expensive or inexpensive the jewelers in your hometown are. I’d say it’s maximum extra $50. So, the total cost would be $350.
They sold this pair of earrings for AUD 1200 on invaluable.com which translates into $ 828 + 30% buyers premium = $1076
This is something to consider, don’t you think so? 🙂 $1076 vs $350 😉
