Questions, answered
How do I know my ring size at home?
Wrap a strip of non-stretching paper around the base of your finger, mark where it overlaps, and measure the distance in millimeters. Match that number to the circumference in our size tool. For the best fit, measure at the end of the day when hands are warmest.
Which metal suits me best?
It depends on your undertone. Cool skin undertones glow in silver and white gold; warm undertones look rich in yellow gold; neutral skin flatters both equally well.
How is my jewelry box melt value calculated?
Melt value calculates the pure weight of precious metal (grams × karat purity) multiplied by current spot market rates. It represents raw scrap metal value without retail markups.
Can I wear my jewelry in the shower?
It is best not to. Soap film dulls diamonds, and chlorinated water erodes gold plating and weakens silk pearl strands. Solid gold and platinum tolerate moisture better than silver or vermeil.
