Ring is a type of item in Harvest Moon 3D: A New Beginning. It can be purchased from the General Store for 30,000G, after the player has reached a blue heart color with a marriage candidate. It can be used by the player to ask a marriage candidate to date them.
The player can show a marriage candidate to propose dating the character. The marriage candidate will only accept the ring if they are at a blue heart color or higher and if they are proposed to on Saturday or Sunday on a sunny day, between 8:00 am and 11:00 pm. The proposal time is different for the Witch Princess and Soseki since they get up at different times than other characters. Both must be proposed to on a sunny Saturday or Sunday, but the Witch Princess will only accept between 2:00 pm and 3:00 am, and Soseki will only accept between 9:00 am and 10:00 pm.
If the character accepts the ring, then they will start to date the player, which in addition allows the player to see their green and yellow heart events.
A marriage candidate can also propose dating to the player, in certain circumstances. This occurs when the player has given the character at least 100 gifts, have at least 25,000FP with the character, and have a ring in their rucksack. When those conditions are met and the player walks into the character's house, or shop in the case of Yuri, on a sunny Saturday or Sunday, then the character will reveal their feelings for the player and ask them if they want to date them.
If the player accepts then they will give the character their ring and they will start dating, which in addition allows the player to see their green and yellow heart events.. However if the character does not accept the character's proposal, then the player will lose 3,000FP with the character and the character will gain 5 anger points. After a reverse proposal has been rejected, then the character can not be proposed to or preform a reverse proposal until the player has given them a total of 130 gifts, including gifts given before the reverse proposal, and it has been at least 7 days since the player refused the character's reverse proposal.
