The best of both worlds, our Door Knocker Studs are both stud and hoop. Featuring a 0.5 ct rose-cut diamond on a post closure, the Door Knocker Studs also host a 5.1mm, forward facing gold hoop. Modern and versatile, they’re a style all their own (for when you can’t decide what to wear).

Each diamond is individually graded and accompanied by a Diamond Foundry certificate.

• Each earring measures 5mm in diameter
• .50ct average diamond weight per earring (.48ct minimum diamond weight)
• 1.0ct total diamond weight for the pair
• Made from 18k solid gold in DTLA
• Double notch earring posts for added security

DIAMOND COLOR: H+

DIAMOND CLARITY: SI1+

DIAMOND CUT: VERY GOOD+

Gold:  All of our Black Label pieces are made from 18k solid gold, a durable gold with a higher purity grade that’s made to last. Containing more gold content than its 14k counterparts, 18k solid gold can withstand daily use but it still a precious metal with high gold content. Handle with care so that your piece retains its shine.
Diamond Foundry: 

Sustainably grown through technology in Silicon Valley, Diamond Foundry is supplying a closed door industry with a traceable, sustainable, real alternative to mined diamonds. All diamonds are D-H color and SI+ quality.

Diamond Foundry

The team of Silicon Valley engineers uses solar technology to recreate the environment in which diamonds grow— creating a completely sustainable, traceable and transparent process in Northern California. The result is a real diamond; identifiable by the traditional 4 C’s (cut, carat, color, clarity), without the environmental damage or questionable ethics of the traditional industry.

DIAMOND CUT

Round Rose Cut

An exciting, reverse take on a traditional diamond cut, the Round Rose cut dates back to the 1800’s. It features a flat bottom and dome-like shape that narrows into a single apex, and offers an enthralling, eye catching alternative to a more classic cut.
