There is something honest about natural colour. No two stones are ever quite the same.
This earrings is made in solid 14K White Gold, not plated and not gold-filled. The colour runs the whole way through, so it will not wear thin at the edges or change tone over the years. It is the balance most people want: rich enough to read unmistakably as gold, hard enough to wear every day.
It is set with lab-grown sapphires. Lab-grown stones are chemically, physically and optically identical to mined sapphires, with the same hardness and the same fire, which means you can wear noticeably more carat for the same money.
The details you actually notice when you wear it: a polished finish, around 1.28 g of metal, so it has real weight in the hand rather than feeling hollow.
Use the options above to choose your metal - the photo updates to match whichever you pick. Every combination is the same solid metal and the same standard of finish.
Given as a gift, this is the kind of piece that gets remembered.

Delivery and care
Please allow 2 to 3 weeks for delivery. Each piece is prepared, inspected and shipped by us personally. To keep it looking its best, store it away from harder stones and clean it now and then with warm water, a drop of washing-up liquid and a soft brush.
Every piece is inspected here before it ships. We do not send anything we would not wear ourselves.

Craftsmanship & Materials
Craftsmanship & Materials
Gemtastic is an independent fine-jewelry studio in Brooklyn Park, Minnesota. Pieces we make ourselves are cast and hand-finished at our own bench. Every piece is checked over by hand in our workshop before it goes out. Metal and stone specifications are stated on each product page — if a detail you need is not there, ask us and we will measure it.
Shipping & Returns
Shipping & Returns
Free insured shipping on orders of $250 or more. Below $250, insured shipping is $9.95. Either way your piece ships insured and tracked, in packaging that does not advertise its contents. We ship to United States addresses only. If a package is delayed, lost, or arrives damaged, contact us and we will handle the carrier claim and the resolution with you directly.
You have 7 days from delivery to contact us if a piece is faulty, has a manufacturing fault, arrived damaged in transit, or is materially different from how it was described. We will repair, replace, or refund it, and you pay no restocking fee on our mistake.
Return shipping is paid by you, including on a confirmed fault. Send the piece back insured and tracked — we will tell you how before you ship anything.
A fault is the only ground for a return.
Because we size and prepare each order to the person, we do not accept a return for change of mind. The piece must be unworn and in its original condition. Seven days is short — please inspect your piece the day it arrives.
Full terms, including when a 25% restocking fee applies, are in our Refund Policy.
