Highest bid in chat when the timer ends takes the stone  ·  @mineandgrown

How it works

Four steps, start to finish

Live selling sounds chaotic until you have done it once. Here is the whole process.

01

Join the auction

Follow the account so you get pushed the moment one opens. Three a day at 8 AM, 6 PM and 10 PM EST.

02

See it up close

Each stone goes under the loupe on camera with its report number on screen. Ask for any angle you want.

03

Bid in chat

Type your bid. Highest one when the timer ends takes the stone, and a secure payment link goes out right after.

04

It ships insured

Out within one business day, signature required, with thirty days to send it back for any reason.

The diamond guide

Four grades set the price. One sets the sparkle.

Know these before you bid and you will spend your money in the right place.

Cut

How well the stone was proportioned and polished. This is the one you notice from across a room, and nothing that goes up for auction grades below good.

Ideal to good

Color

Graded D through Z, colorless to warm. Judged face down against a white tray, not the way you will ever see it.

G through I is the value

Clarity

The size and position of inclusions inside the stone, viewed at ten times magnification.

VS2 and SI1 look clean

Carat

Weight, not size. Price jumps at every round number because that is where the demand piles up.

Buy just under
